Product Description

Theory of Operation

An uninterruptible power supply is a system that is installed between the commercial power and the load equipment. The UPS provides steady ac output power during commercial power short-term blackouts or brownouts. This power is provided for a long enough time so that the load can be shut down in an orderly fashion. This prevents loss of data and possible damage to both hardware and software.

During normal operation, the UPS uses commercial ac power. In addition, it takes in all of the high voltage spikes and transients caused by switching and faults, and all of the common- mode and normal mode noise which is associated with commercial ac power. The UPS converts it all to flat dc power. From this power, the UPS charges its batteries and

generates its own extremely high quality ac waveform output. The result of this process is maximum power conditioning and regulation.

If the ac power supplied to the UPS drops below a specified voltage level, the unit's batteries automatically begin supplying power instead of receiving it. This insures that the loads connected to the UPS continue to receive power with no interruption. When ac input power becomes available again, operation returns to normal. The unit's batteries begin to recharge so they will be ready for the next power interruption.

Application and Use

Toshiba's 1600EP Series of on-line uninterruptible power supply (UPS) systems provide continuous computer-grade ac power in a compact, high performance, and energy efficient unit. The UPS unit assures safe and reliable operation of critical office equipment. This can range from word processors and personal computers to mini-computers and local area networks. All units feature an audible alarm which sounds if the battery voltage drops below standard during use. This is an additional aid to help in retaining the valuable office data banks. All units allow for computer interfacing.

Output Rating

Toshiba's 1600EP Series (208/240V) offers UPS models with the following capacities:

Power Backup

When an electrical power failure occurs, the UPS???s internal batteries automatically supply back- up power to the load without interruption. For example, when used to support a computer, the UPS back-up assures enough additional time to complete the activity and store the data. This allows an orderly shutdown after a power failure has occurred.

Power Conditioning

When commercial power is present, the UPS supplies conditioned power to the load while maintaining its batteries in a charged condition. The UPS protects against the normal, everyday problems associated with heavy use of raw commercial power, including power sags,

surges, signal interference, and spikes. This protection keeps power-line problems from reaching your load, where they can cause equipment to operate erratically, or damage software and hardware.

Inspection/Storage/Disposal

Inspection of the new UPS equipment

Upon receipt of the UPS, a careful inspection for shipping damage should be made.

After Uncrating:

1)Check the unit for loose, broken, bent or otherwise damaged parts. If damage has occurred during shipment, keep all original crating and packing materials for return to shipping agent. Warranty will not apply to units which are damaged during shipment.

2)Check to see that the rated capacity and the model number specified on the nameplate conform to the order specifications.

Storage of UPS Equipment

If the UPS equipment is to be subject to long or short term storage the following guidelines should be used.

Avoid:

1)Storage in sites subject to extreme changes in temperature or high humidity.

2)Storage in sites subject to exposure of high levels of dust or metal particles

3)Storage on inclined floor surfaces or in sites subject to excessive vibration.

Before Storing:

1)Allow UPS to be operated for 24 hrs. to ensure that the batteries are fully charged.

2)Stop the unit (see "Stopping the UPS" on page 41).

3)Place the unit's MCCB switch (see pages 45-46 for location) in the "off" position.

Storing:

1)Store within a temperature range of -20 ~ 40?? C (-4 to 104?? F).

2)For best results, store the UPS in the original shipping container and place on a wood or metal pallet.

3)The optimum storage temperature is 21?? C (70?? F). Higher ambient temperatures cause UPS batteries to need recharging more frequently.

After Storing:

1)If stored in an ambient temperature under 20?? C (68?? F), recharge the batteries every 9 months.

2)If stored in an ambient temperature of 20?? to 30?? C (68?? to 86?? F), recharge the batteries every 6 months.

3)If stored in an ambient temperature of 30?? to 40?? C (86?? to 104?? F), recharge the batteries every 3 months.

Disposal

Please contact your state environmental agency for details on disposal of electrical components and packaging in your particular area.

It is illegal to dump lead-acid batteries in landfills or dispose of improperly.

Please help our Earth by contacting the environmental protection agencies in your area, the battery manufacturer, or call Toshiba toll-free at (800) 231-1412 for more information about recycling.

11

1)Install the unit in a well-ventilated location; allow at least 10 cm (4 inches) on all sides for air ventilation and for maintenance.

2)Install the unit in a stable, level, and upright position which is free of vibration.

3)Install the unit where the ambient temperature is within the correct operating range (see UPS Specifications pages 18 - 21).

4)Do not install the UPS in areas that are subject to high humidity.

5)Do not allow direct sunlight to shine on the unit.

6)Do not install the UPS in areas which are subject to contamination such as high levels of airborne dust, metal particles, or inflammable gas.

7)Avoid installation near sources of electrical noise, and always make sure that the unit earth ground is intact to prevent electrical shock and to help reduce electrical noise.

8)Do not install where water or any foreign object may get inside the UPS.

9)This UPS generates and can radiate radio-frequency energy during operation. Although RFI noise filters are installed inside the unit there is no guarantee that the UPS will not influence some sensitive devices which are operating close by. If such interference is experienced, the UPS should be installed farther away from the affected equipment and/or powered from a different source than that of the affected equipment.

10)User should provide output over current protection for hardwired UPS versions.

See Safety Instructions on page 8 for the correct device rating.

1)The UPS should not be powered up until the entire operation manual has been reviewed.

2)The input power source voltage must be within +10% to -30% of the rated input voltage. The input frequency must be within the rated input frequency range. Voltages and frequencies outside of the permissible tolerance range may cause internal protection devices to activate.

3)The UPS should not be used with a load whose rated input is greater than the rated UPS output.

4)Do not use the UPS to provide power to motors that require high starting current or a long starting time such as vacuum cleaners and machine tools (over sizing for lock rotor current required).

5)Do not insert metal objects or combustible materials in the unit's ventilation slots.

6)Do not place, hang, or paste any objects on the top or on the exterior surfaces of the UPS.

UPS Stop Signal Operation

When the UPS stop signal is sent to the UPS through pin 2 and 3 of the external contact interface, it is possible to automatically reset the following operating systems (OS), which can automatically implement the shutdown function and restart the operation:

Applicable OS: Windows NT, IBM OS/2 LAN server, LANtastic

When the power fails, the OS detects the power failure signal from the UPS and starts the shutdown process.

At the end of the shutdown process, the OS outputs a stop signal to the UPS, and the UPS stops.

When the power recovers, the UPS automatically starts output and restarts the OS. Even when the power recovers while in a shutdown process, the UPS temporarily cuts off the output (10 - 20 seconds) and then restarts the OS within 10 minutes after the recovery from power failure. In this case the UPS cuts off output even with normal input power. Connect the UPS stop signal of the external contact interface only for the automatic processing so that the UPS output will not be cut off by mistake. If a stop signal is sent to the UPS ten minutes or more after the recovery from a power failure, then the UPS ignores this signal and continues to output power.

If the computer is started/restarted within 10 minutes after the recovery from a power failure, the power supply may be reset while the computer is restarting.

Battery Backup Time and Discharge Process

The UPS batteries provide about 5-7 minutes of back-up time depending on the 1600EP unit kVA rating. These times are valid when the unit is operating under full load and at the rated power factor. When these models are operating at half load, the batteries can provide about 15-20 minutes of back-up time. The exact length of these times will depend on the UPS model used, condition of the batteries, amount and type of load, temperature and other variables. See battery backup time in 'Standard Specifications' beginning on pages 18-21.

Time

The recharge process usually consists of three periods. During the first period, the current is maintained at approximately 1 ampere. This current limit is the maximum value that can be used to charge the batteries (for minimal recharge time) while assuring safety and long battery life. In the second period, constant-voltage control starts and current gradually decreases as the batteries charge to their normal fully charged state. In the third period, a slight "trickle" current continues to flow into the batteries to keep them fully charged and "floating" at the normal Vdc level. A full recharge usually requires 24 hours (90% recharge in 12 hours) after

a complete discharge.

The following chart shows the rated maximum and minimum battery voltages and the charge current for each of the sizes.

Operating the UPS

Operation Modes

AC Input Mode (normal operation) The following illustration shows circuit power flow when the UPS is operating normally in the ac input mode. The UPS rectifier, including a boost chopper circuit, converts ac input power to dc power. The boost chopper circuit maintains a constant voltage, with current limiting, for charging the batteries. It also supplies a dc voltage of the proper level to the inverter section. The inverter section generates a high quality sine wave output voltage. The unit's batteries are always maintained in a constantly charged state when the UPS is in the normal operation mode.

Power Flow in AC input mode for all models

Circuit-bypass Mode

If the UPS unit is severely overloaded or develops an internal fault, power flow is Automatically switched from the unit's main circuit to the bypass circuit. Power flow through the bypass is shown in the following illustration. This change-over occurs automatically in less than 4 milliseconds in phase. The switching period is not long enough to cause interruptions to occur in most loads. If the power flow is transferred to the bypass circuit because of an overload and that overload condition ends within a specified period of time then the power flow will be transferred back to the AC input mode (normal operation) automatically. If the power flow is transferred to the bypass circuit due to an external fault the UPS will shut down power through the bypass to the load and indicate a system fault message. If the power flow is transferred to the bypass circuit due to an internal fault the UPS will continue to supply power to the load through the bypass and indicate a system fault message (see system fault message DC-OC on page 43). If the power flow is transferred to the bypass circuit due to an overload condition (see system warning message OL: REDUCE LOAD on page 36 and AUTO RETRANSFER on page 40), then the power flow will automatically transfer from the UPS's bypass circuit back to the inverter circuit after removing the overload if set to do so (see auto- transfer setting on page 34).

Battery Backup Mode

The following illustration shows power flow during the battery backup mode. When commercial ac power failures occur, the UPS's batteries instantly begin supplying dc voltage to the UPS's main inverter circuit. This circuit changes (inverts) the dc power into ac power. The ac power is available at the unit's output. This back-up process will continue until the UPS's battery voltage drops below a specific minimum level. When this occurs, the batteries will stop supplying power to the load. This minimum level is the rated minimum voltage (Vmin). The rated battery voltage chart on page 22 shows (Vmin). The battery backup time and discharge process is explained on page 22.

Power flow in battery backup mode for all models

EPO (Emergency Power Off) Function

These units are equipped with terminals for receiving an emergency power-off (EPO) "closed contact" switch command from a remote location (see 'terminal block details' on page 13 and terminalblock location on page 45-46). This safety feature enables quick shut-down of the UPS's

ac output and battery circuits. Usually the emergency power off switch is installed in a central location that is easily accessible to personnel concerned with the operation of the UPS unit and the load equipment connected to it. The EPO function is initiated by pressing the switch to the closed "shutdown" position. The effect of using the EPO switch is the same whether the UPS unit is in the ac input mode (see page 24), battery backup mode (see page 25), or the circuit bypass mode (see page 24). The following figure shows the UPS condition after application of the EPO switch.

Preventive Maintenance/Parts Replacement

Preventive Maintenance

Toshiba's 1600EP Series of uninterruptible power systems have been designed to provide years of

trouble-free operation requiring a minimum of preventive maintenance.

The best preventive measure that the UPS user can take is to keep the area around the unit, particularly the air inlet vents, clean and free of moisture and dust accumulations.
