2. INSTALLATION

2.1 Wiring Guidelines to Minimise the Effects of EMI

The inverters are designed to operate in an industrial environment where a high level of Electro-Magnetic Interference (EMI) can be expected. Usually, good installation practices will ensure safe and trouble-free operation. However, if problems are encountered, the following guidelines may prove useful. In particular, grounding of the system 0V at the inverter, as described below, may prove effective. Figure 1 illustrates how an RFI suppression filter should be installed.

(1)Ensure that all equipment in the cubicle is well earthed using short, thick earthing cable connected to a common star point or busbar. It is particularly important that any control equipment that is connected to the inverter (such as a PLC) is connected to the same earth or star point as the inverter via a short, thick link. Flat conductors (e.g. braids or metal brackets) are preferred as they have lower impedance at high frequencies.

The return earth from motors controlled by the inverters should be connected directly to the earth connection (PE) on the associated inverter.

(2)Wherever possible, use screened leads for connections to the control circuitry. Terminate the ends of the cable neatly, ensuring that unscreened wires are as short as possible. Use cable glands whenever possible.

(3)Separate the control cables from the power connections as much as possible, using separate trunking, etc. If control and power cables cross, arrange the cables so that they cross at 90?? if possible.

(4)Ensure that contactors in the cubicle are suppressed, either with R-C suppressors for AC contactors or ???flywheel??? diodes for DC contactors,fitted to the coils. Varistor suppressors are also effective. This is particularly important if the contactors are controlled from the relay on the inverter.

(5)Use screened or armoured cables for the motor connections and ground the screen at both ends via the cable glands.

(6)If the drive is to be operated in an Electro-magnetic noise-sensitive environment, the RFI footprint filter kit should be used to reduce the conducted and radiated interference from the inverter. For optimum performance, there should be a good conductive bond between filter and metal mounting plate.

On no account must safety regulations be compromised when installing inverters!

2.2 Mechanical Installation

Ideal Installation

2.3 Electrical Installation

The electrical connectors on the MICROMASTER are shown in Figure 3. Connect the cables to the power and control terminal blocks in accordance with the information supplied in sections 2.3.1 - 2.3.4. Ensure that the leads are connected correctly and the equipment is properly earthed as shown in Figure 3.

CAUTION

The control, power supply and motor leads must be laid separately. They must not be fed through the same cable conduit/trunking.

Use screened cable for the control lead. Use Class 1 60/75oC copper wire only (for UL compliance). Tightening torque for the power (mains input and motor) terminals is 1.1 Nm.

To tighten up the power/motor terminal screws use a 4 - 5 mm cross-tip screwdriver.

2.3.1 Power and Motor Connections - Frame Size A

Ensure that the power source supplies the correct voltage and is designed for the necessary current (see section 7). Ensure that the appropriate circuit-breakers/fuses with the specified current rating are connected between the power supply and inverter (see section 7).

Connect the power and motor connections as shown in Figure 3.

WARNING

Isolate the supply before making or changing connections.

Ensure that the motor is configured for the correct supply voltage. Single/three phase 230 V

MICROMASTERS must not be connected to a 400 V three phase supply.

When synchronous machines are connected or when coupling several motors in parallel, the inverter must be operated with voltage/frequency control characteristic (P077= 0 or 2).

2.3.2 Power and Motor Connections - Frame Size B

The terminal arrangement for frame size B is identical to frame size A (see Figure 3). However, before the wires can be connected to the terminal blocks, you must lower the terminal access panel and secure the cables to the gland plate.

Refer to Figures 3 and 4. Proceed as follows:

1.Insert the blade of a small screwdriver into slot A on the side of the inverter and press in the direction of the arrow. At the same time, apply finger pressure to clip B on the other side of the access panel and press in the direction of the arrow.

This will release the access panel, which will then swing down on its rear-mounted hinges.

2.Remove the gland plate by applying pressure to release clips C and D in the direction of the arrows.

3.Secure each cable to the correct hole in the gland plate, ensuring that the exposed wires are long enough to reach the terminal blocks.

4.Before refitting the gland plate, feed the control wires (if used) through hole 1 and the mains input and motor wires through hole 2. IT IS MOST IMPORTANT THAT THE MOTOR AND CONTROL WIRES ARE

KEPT APART.

5.Refit the gland plate. Ensure that the release clips snap into position.

6.Connect the wires to the terminal blocks as shown in Figure 3. (See section 2.3.4 for information about connecting the control wires.)

7.Close the terminal access panel.

2.3.3 Power and Motor Connections - Frame Size C

The terminal arrangement for frame size C is identical to frame size A (see Figure 3). However, before the wires can be connected to the terminal blocks, you must lower the fan housing and secure the cables to the gland plate.

Refer to Figure 5 and proceed as follows:

1.While supporting the fan housing with one hand, insert the blade of a screwdriver into slot A on the underside of the inverter and press upwards to release the securing tab. Lower the fan housing, allowing it to swing out to the right on its side-mounted hinges.

2.Applying pressure to the gland plate release clips B and C in the direction of the arrows. Swing the plate out to the left on its side-mounted hinges,

3.Secure each cable to the correct hole in the gland plate, ensuring that the exposed wires are long enough to reach the terminal blocks.

4.Connect the wires to the terminal blocks as shown in Figure 3. (See section 2.3.4 for information about connecting the control wires.) IT IS MOST IMPORTANT THAT THE MOTOR AND CONTROL WIRES

ARE KEPT APART.

5.Swing the gland plate back into the base of the inverter. Ensure that the release clips snap into position.

3. FRONT PANEL CONTROLS & BASIC OPERATION

3.1 Front Panel Controls

CAUTION

The digital frequency setpoint has been set at 5.00 Hz in the factory. This means that, it is not necessary to enter a frequency setpoint via the button or parameter P005 in order to test that the motor turns following a RUN command.

All settings must only be entered by qualified personnel, paying particular attention to the safety precautions and warnings.

The parameter settings required can be entered using the three parameterisation buttons (P, and ???) on the front panel of the inverter. The parameter numbers and values are indicated on the four digit LED display.

3.2 Basic Operation

Refer to section 5 for a full description of each parameter.

3.2.1 General

(1)The inverter does not have a main power switch and is live when the mains supply is connected. It waits, with the output disabled, until the RUN button is pressed or for the presence of a digital ON signal at terminal 5 (rotate right) or terminal 6 (rotate left) - see parameters P051 - P053.

(2)If output frequency is selected to be displayed (P001 = 0), the corresponding setpoint is displayed approximately every 1.5 seconds while the inverter is stopped.

(3)The inverter is programmed at the factory for standard applications on Siemens four-pole standard motors. When using other motors it is necessary to enter the specifications from the motor???s rating plate into parameters P081 to P085 (see Figure 10). Note: Access to these parameters is not possible unless P009 has been set to 002 or 003.

P084

P083 P082 P085

Figure 10: Typical Motor Rating Plate Example

Note: Ensure that the inverter is configured correctly to the motor, i.e. in the above example delta terminal connection is for 220 V.

3.2.2 Initial Testing

(1)Check that all cables have been connected correctly (section 2) and that all relevant product and plant/location safety precautions have been complied with.

(2)Apply mains power to the inverter.

(3)Ensure that it is safe to start the motor. Press the RUN button on the inverter. The display will change to 5.0 and the motor shaft will begin to turn. It will take one second for the inverter to ramp up to 5 Hz.

(4)Press the STOP button. The display will change to 0.0 and the motor slow to a complete stop within one second.

3.2.3 Basic Operation - 10 Step Guide

The basic method of setting up the inverter for use is described below. This method uses a digital frequency setpoint and requires only the minimum number of parameters to be changed from their default settings. It assumes that a standard Siemens four-pole motor is connected to the inverter (see section 3.2.1 if a different motor type is being used).

Step /Action

1. Apply mains power to the inverter.

The display will alternate between the actual frequency (0.0 Hz) and the requested frequency setpoint (5.0 Hz default).

2. Press the parameterisation button.

3. Press the button until parameter P005 is displayed.

4. Press P to display the current frequency setpoint (5 Hz is the factory default setting).

5. Press the button to set the desired frequency setpoint (e.g. 35 Hz).

Button Display

6. Press P to lock the setting into memory.

7, Press the ??? button to return to P000.

8. Press P to exit the parameterisation procedure.

The display will alternate between the current frequency and the requested frequency setpoint.

9. Start the inverter by pressing the RUN button.

The motor shaft will start to turn and the display will show that the inverter is ramping up to the setpoint of 35 Hz.

Note

The setpoint will be achieved after 7 seconds (35 Hz/50 Hz x 10 s *). If required, the motor???s speed (i.e. frequency) can be varied directly by using the ??? buttons. (Set P011 to 001 to enable the new frequency setting to be retained in memory during periods when the inverter is not running.)

10. Switch the inverter off by pressing the STOP button.

The motor will slow down and come to a controlled stop (takes 7 s **).

*Default ramp-up time is 10 s to reach 50 Hz (defined by P002 and P013).

**Default ramp-down time is 10 s from 50 Hz (defined by P003 and P013).

4. OPERATING MODES

4.1 Digital Control

For a basic startup configuration using digital control, proceed as follows:

(1)Connect control terminal 5 to terminal 8 via a simple on/off switch. This sets up the motor for clockwise rotation (default).

(2)Apply mains power to the inverter. Set parameter P009 to 002 or 003 to enable all parameters to be adjusted.

(3)Check that parameter P006 is set to 000 to specify digital setpoint.

(4)Set parameter P007 to 000 to specify digital input (i.e. DIN1 (terminal 5) in this case) and disable the front panel controls.

(5)Set parameter P005 to the desired frequency setpoint.

(6)Set parameters P081 to P085 in accordance with the rating plate on the motor (see Figure 10).

Note: In many cases, when default factory parameters are used, the default stator resistance set in P089 will generally suit the default power rating set in P085. Should the inverter and motor ratings differ greatly, it is recommended that the stator resistance of the motor is measured and entered manually into P089. Continuous Boost (P078) and Starting Boost (P079) are dependent on the value of Stator Resistance - too high a value may cause overcurrent trips

(7)Set the external on/off switch to ON. The inverter will now drive the motor at the frequency set by P005.

4.2 Analogue Control

For a basic startup configuration using analogue voltage control, proceed as follows:

(1)Connect control terminal 5 to terminal 8 via a simple on/off switch. This sets up the motor for clockwise rotation (default).

(2)Connect a 4.7 k?? potentiometer to the control terminals as shown in Figure 6 or connect pin 2 (0V) to pin 4 and a 0 - 10 V signal between pin 2 (0V) and pin 3 (AIN+).

(3)Apply mains power to the inverter. Set parameter P009 to 002 or 003 to enable all parameters to be adjusted.

(4)Set parameter P006 to 001 to specify analogue setpoint.

(5)Set parameter P007 to 000 to specify digital input (i.e. DIN1 (terminal 5) in this case) and disable the front panel controls.

(6)Set parameters P021 and P022 to specify the minimum and maximum output frequency settings.

(7)Set parameters P081 to P085 in accordance with the rating plate on the motor (see Figure 10).

(8)Set the external on/off switch to ON. Turn the potentiometer (or adjust the analogue control voltage) until the desired frequency is displayed on the inverter.

?? Siemens plc 1997G85139-H1750-U049-B

4.3 Stopping the Motor

Stopping can be achieved in several ways:

???Cancelling the ON command or pressing the OFF button (O) on the front panel causes the inverter to ramp down at the selected ramp down rate (see P003).

???OFF2 - operation causes the motor to coast to a standstill (see parameters P051 to P053).

???OFF3 - operation causes rapid braking (see parameters P051 to P053).

???DC injection braking up to 250% causes a rapid stop (see P073).

4.4 If the Motor Does Not Start Up

If the display shows a fault code, refer to Section 6.

If the motor does not start up when the ON command has been given, check that the ON command is valid, check if a frequency setpoint has been entered in P005 and check that the motor specifications have been entered correctly under parameters P081 to P085.

If the inverter is configured for operation via the front panel (P007 = 001) and the motor does not start when the RUN button is pressed, check that P121 = 001 (RUN button enabled).

If the motor does not run after parameters have been changed accidentally, reset the inverter to the factory default parameter values by setting parameter P944 to 001 and then pressing P.

4.5 Local and Remote Control

The inverter can be controlled either locally (default), or remotely via a USS data line connected to the RS485 D-type connector on the front panel. (Refer to parameter P910 in section 5 for the available remote control options.)

When local control is used, the inverter can only be controlled via the front panel or the control terminals. Control commands, setpoints or parameter changes received via the RS485 interface have no effect.

When operating via remote control the inverter will not accept control commands from the terminals.

Exception: OFF2 or OFF3 can be activated via parameters P051 to P053 (refer to parameters P051 to P053 in section 5).

Several inverters can be connected to an external control unit at the same time. The inverters can be addressed individually.

For further information, refer to the following documents (available from your local Siemens office):

4.6 Closed Loop Control

4.6.1 General Description

The MICROMASTER provides a PI control function for closed loop control (see Figure 11). PI control is ideal for temperature or pressure control, or other applications where the controlled variable changes slowly or where transient errors are not critical. This control loop is not suitable for use in systems where fast response times are required.

Note: The closed loop function is not designed for speed control, but can be used for this provided that fast response times are not required.

When closed loop PI control is enabled (P201 = 002), all setpoints are calibrated between zero and 100%, i.e. a setpoint of 50.0 = 50%. This allows general purpose control of any process variable that is actuated by motor speed and for which a suitable transducer is available.

Setpoint

P205

Figure 11: Closed Loop Control

4.6.2 Hardware Setup

Connect the outputs from the external feedback transducer to control terminals 3 and 4. This analogue input accepts a 0/2 - 10 V signal, has 10-bit resolution and permits a differential (floating) voltage. Ensure that the values of parameters P023 and P024 are set to 000 and that P006 is set to 000 or 002.

15 V dc power for the feedback transducer can be supplied from terminals 8 and 9 on the control block.

4.6.3 Parameter Settings

Closed loop control cannot be used unless P201 is first set to 002. Most of the parameters associated with closed loop control are shown in Figure 11. Other parameters which are also associated with closed loop control are as follows:

P001 (value = 007)

P061 (value = 012 or 013)

P210

P220

Descriptions of all closed loop control parameters are provided in section 5. For further detailed information about PI operation refer to the Siemens DA 64 Catalogue.

5. SYSTEM PARAMETERS

Parameters can be changed and set using the membrane-type buttons to adjust the desired properties of the inverter, such as ramp times, minimum and maximum frequencies etc. The parameter numbers selected and the setting of the parameter values are indicated in the four digit LED display.

Note: If you press the or ??? button momentarily, the values change step by step. If you keep the buttons pressed for a longer time, the values scroll through rapidly.

Access to parameters is determined by the value set in P009. Check that the key parameters necessary for your application have been programmed.

Note: In the following parameter table:

????????? Indicates parameters that can be changed during operation.

?????? Indicates that the value of this factory setting depends on the rating of the inverter.

To increase the resolution to 0.01 when changing frequency parameters, instead of pressing P momentarily to return to the parameter display, keep the button pressed until the display changes to ???- -.n0??? (n = the current tenths value, e.g. if the parameter value = ???055.8??? then n = 8). Press or ??? to change the value (all values between .00 and .99 are valid) and then press P twice to return to the parameter display.

If parameters are changed accidentally, all parameters can be reset to their default values by setting parameter P944 to 1 and then pressing P.

5. SYSTEM PARAMETERS

Description / Notes

This displays the output selected in P001.

In the event of a fault, the relevant fault code (Fxxx) is displayed (see section 6). In the event of a warning the display flashes. If output frequency has been selected (P001 = 0) and the inverter is OFF, the display alternates between the selected frequency and the actual frequency.

Display selection:

0 = Output frequency (Hz)

This is the time taken for the motor to accelerate from standstill to the maximum frequency as set in P013.

Setting the ramp up time too short can cause the inverter to trip (fault code F002 - overcurrent).

This is the time taken for the motor to decelerate from maximum frequency (P013) to standstill.

Setting the ramp down time too short can cause the inverter to trip (fault code F001 - overvoltage).

This is also the period for which DC injection braking is applied (see P073)

?? Siemens plc 1997G85139-H1750-U049-B

P004 ???

Used to smooth the acceleration/deceleration of the motor (useful in applications where it is important to avoid ???jerking???, e.g. conveyor systems, textiles, etc.).

Smoothing is only effective if the ramp up/down time exceeds 0.3 s.

Total acceleration time = 15 s

Note: The smoothing curve for deceleration is based on the ramp up gradient (P002) and is added to the ramp down time set by P003. Therefore, the ramp down time is affected by changes to P002.

Allows the inverter to start onto a spinning motor.

Under normal circumstances the inverter runs the motor up from 0 Hz. However, if the motor is still spinning or is being driven by the load, it will undergo braking before running back up to the setpoint - this can cause an overcurrent trip. By using a flying restart, the inverter ???homes in??? on the motor's speed and runs it up from that speed to the setpoint.Note: If the motor has stopped or is rotating slowly, some ???rocking??? may occur as the inverter senses the direction of rotation prior to restarting.(See also P020)

0 = Normal restart

1 = Flying restart after power up, fault or OFF2 ( if P018 = 1).

2 = Flying restart every time (useful in circumstances where the motor can be driven by the load).

0 = 0 V to 10 V

1 = 2 V to 10 V

2 = 2 V* to 10 V

* The inverter will come to a controlled stop if V < 1 V.

WARNING: The motor can automatically run without a potentiometer or voltage source connected between pins 3 and 4.

WARNING: With P023=2, the inverter will automatically start when V goes above 1 V. This equally applies to analogue and digital control (i.e. P006 = 0 or 1).

If the inverter is not in analogue mode (P006 = 0 or 2), setting this parameter to ???1??? causes the analogue input value to be added.

0 = No addition.

1 = Addition of the analogue setpoint (defined by P023) to the fixed frequency or the motor potentiometer frequency.

2 = Scaling of digital/fixed setpoint by analogue input (P023) in the range 0 - 100%.

Note: By selecting a combination of reversed negative fixed frequency settings and analogue setpoint addition, it is possible to configure the inverter for ???centre zero??? operation with a +/-5 V supply or a 0 - 10 V potentiometer so that the output frequency can be 0 Hz at any position, including the centre position.

Jogging is used to advance the motor by small amounts. It is controlled via the JOG button or with a non-latching switch on one of the digital inputs (P051 to P053).

If jog right is enabled (DINn = 7), this parameter controls the frequency at which the inverter will run when the switch is closed. Unlike other setpoints, it can be set lower than the minimum frequency.

If jog left is enabled (DINn = 8), this parameter controls the frequency at which the inverter will run when the switch is closed. Unlike other setpoints, it can be set lower than the minimum frequency.

Sets the baud rate of the RS485 serial interface (USS protocol):

3= 1200 baud

4= 2400 baud

5= 4800 baud

6= 9600 baud

7= 19200 baud

Note: Some RS232 to RS485 converters are not capable of baud rates higher than 4800.

This is the maximum permissible period between two incoming data telegrams. This feature is used to turn off the inverter in the event of a communications failure.

Timing starts after a valid data telegram has been received and if a further data telegram is not received within the specified time period, the inverter will trip and display fault code F008.

Setting the value to zero switches off the control.

Setpoints are transmitted to the inverter via the serial link as percentages. The value entered in this parameter represents 100% (HSW = 4000H).

0 = Compatible with 0.1 Hz resolution

1 = Enable 0.01 Hz resolution

2 = HSW is not scaled but represents the actual frequency value to a resolution of 0.01 Hz (e.g. 5000 = 50 Hz).

0 = Option module not present

1 = PROFIBUS module (enables parameters relating to PROFIBUS)

This sets the inverter for European or USA supply and motor frequency:

0 = Europe (50 Hz)

1 = USA (60 Hz)

Note: After setting P101 = 1 the inverter must be re-set to factory defaults. i.e. P944 = 1 to automatically set P013 = 60 Hz, P081 = 60 Hz, P082 = 1680 rpm and P085 will be displayed in hp.

Read-only parameter that indicates the power rating of the inverter in kW. e.g. 0.55 = 550 W

Check whether supply voltage is within the limits indicated on the rating plate. Increase the ramp down time (P003).

Check whether the required braking power is within the specified limits.

Check whether the motor power corresponds to the inverter power. Check that the cable length limits have not been exceeded.

Check motor lead and motor for short-circuits and earth faults.

Check whether the motor parameters (P081 - P086) correspond with the motor being used.

Check the stator resistance (P089). Increase the ramp-up time (P002). Reduce the boost set in P078 and P079.

Check whether the motor is obstructed or overloaded.

Check whether the motor is overloaded.

Increase the maximum motor frequency if a motor with high slip is used.

Check that the ambient temperature is not too high.

Check that the air inlet and outlet are not obstructed.

Check that the integral fan is working.

Check the serial interface.

Check the settings of the bus master and P091 - P093.

Check whether the timeout interval is too short (P093).

Check the entire parameter set. Set P009 to ???0000??? before power down.

Switch off power and switch on again.

Check if motor is overloaded.

Switch off power and switch on again.

Automatic re-start after fault (P018) is pending.

WARNING: The inverter may start at any time.

Check the integrity of the link.

Check the PROFIBUS configuration.

Replace PROFIBUS module

Check that the motor current does not exceed the value set in P083.

Parameterise fixed frequency(ies) and/or motor potentiometer on the digital inputs.

Set parameter P012 < P013.

Check the settings of digital inputs P051 to P053.

Motor not connected to inverter - connect motor.

If the fault persists, set P088 = 0 and then enter the stator resistance of the motor into P089 manually.

Change parameter P006 and/or P201.

Set parameter P211 < P212.

* Ensure that the wiring guidelines described in section 2.1 have been complied with.

When the fault has been corrected the inverter can be reset. To do this press button P twice (once to display P000 and the second time to reset the fault), or erase the fault via a binary input (see parameters P051 - P053 in section 5) or via the serial interface.

8.3 Electro-Magnetic Compatibility (EMC)

All manufacturers / assemblers of electrical apparatus which performs a complete intrinsic function which is placed on the market as a single unit intended for the end user must comply with the EMC directive EEC/89/336 after January 1996. There are three routes by which the manufacturer/assembler can demonstrate compliance:

1.Self-Certification

This is a manufacturer???s declaration that the European standards applicable to the electrical environment for which the apparatus is intended have been met. Only standards which have been officially published in the Official Journal of the European Community can be cited in the manufacturer???s declaration.

2.Technical Construction File

A technical construction file can be prepared for the apparatus describing its EMC characteristics. This file must be approved by a ???Competent Body??? appointed by the appropriate European government organisation. This approach allows the use of standards which are still in preparation.

3.EC Type-Examination Certificate

This approach is only applicable to radio communication transmitting apparatus.

The MICROMASTER units do not have an intrinsic function until connected with other components (e.g. a motor). Therefore, the basic units are not allowed to be CE marked for compliance with the EMC directive. However, full details are provided below of the EMC performance characteristics of the products when they are installed in accordance with the wiring recommendations in section 2.1.

Three classes of EMC performance are available as detailed below. Note that these levels of performance are only achieved when using the default switching frequency (or less) and a maximum motor cable length of 25 m.

Class 1: General Industrial

Compliance with the EMC Product Standard for Power Drive Systems EN 68100-3 for use in Second Environment (Industrial) and Restricted Distribution.

* Limits not required inside a plant where no other consumers are connected to the same electricity supply transformer.

Class 2: Filtered Industrial

This level of performance will allow the manufacturer/assembler to self-certify their apparatus for compliance with the EMC directive for the industrial environment as regards the EMC performance characteristics of the power drive system. Performance limits are as specified in the Generic Industrial Emissions and Immunity standards EN 50081-2 and EN 50082-2.

Immunity:

Supply Voltage Distortion

Voltage Fluctuations, Dips, Unbalance,

Frequency Variations

IEC 1000-2-4 (1993)

IEC 1000-2-1

Class 3: Filtered - for residential, commercial and light industry

This level of performance will allow the manufacturer / assembler to self-certify compliance of their apparatus with the EMC directive for the residential, commercial and light industrial environment as regards the EMC performance characteristics of the power drive system. Performance limits are as specified in the generic emission and immunity standards EN 50081-1 and EN 50082-1.

Note:

The MICROMASTERS are intended exclusively for professional applications. Therefore, they do not fall within the scope of the harmonics emissions specification EN 61000-3-2.

*Class B filters are for use with 1/3 AC 230V unfiltered units.

8.4Environmental Aspects

Transport and Storage

Protect the inverter against physical shocks and vibration during transport and storage. The unit must also be protected against water (rainfall) and excessive temperatures (see section 7).

The inverter???s packaging is re-usable. Retain the packaging or return it to the manufacturer for future use.

If the unit has been in storage (non-operational) for more than one year, you must re-form the DC-link capacitors before use. Refer to your local Siemens sales office for advice on the procedure.

Dismantling and Disposal

The unit can be broken-down to its component parts by means of easily-released screw and snap connectors.

The component parts can be re-cycled, disposed of in accordance with local requirements or returned to the manufacturer.
