Replacing the Power Supply
DANGER
Installation and maintenance of ACCESS meters and meter options should only be performed by qualified personnel that have appropriate training and experience with high voltage/current devices. Refer to Installation Considerations, and the Danger, Warning, and Limitation of Liability notices in the 9200 Installation and Operation Guide.
1.Turn off all power to the meter.
2.Ensure that all cables still connected to the meter are not live.
3.Ensure that the Line and Neutral (or DC power) wires to the power supply inputs of the meter are not live (if you are replacing an existing power supply).
4.Fit the power supply plug-in connector to the meter plug-in port.
NOTE
All 9200 power supply models are installed the same way; the diagram for the 480V power supply is included to show the greater depth dimension of that model.
5.Tighten the two (captive) screws until the power supply fits snugly against the meter. Do not overtighten the screws.
Plugging in the Power Supply
Wiring the Power Supply
The meter requires a constant power supply to maintain monitoring, analysis, control, and communications operations. Powering the device from the voltage source it is monitoring is not suitable for applications where these operations must be maintained in the event of a power outage.
Wiring the Standard AC/DC or Low Voltage DC Power Supply
Use 18 to 14 AWG (0.8mm2 to 2.1mm2) wire
2A fuse on L+ and N-. DO NOT install the N- fuse in a grounded neutral power system
G L+ N-
Standard AC/DC Power Supply
Connect the line supply wire to the L+ terminal and the neutral supply wire to the N- terminal.
Low Voltage DC Power Supply
Connect the positive supply wire to the L+ terminal and the negative supply wire to the N- terminal.
The power supply G (ground) terminal must be connected to the same point as the meter
terminal.
Protective Fuses
If a Standard AC/DC or a Low Voltage DC power supply is being used, install a Type T (slow blow) 2A fuse on the L+ conductor. If the meter is powered by a grounded neutral power system, a fuse must NOT be installed on the neutral wire. If the line connected to the N/- terminal is not grounded in the breaker panel, then install a Type T (slow blow) 2A fuse on the N- terminal.
Wiring the 480V Power Supply
Use18 to 14 AWG (0.8mm2 to 2.1mm2) wires
Connections to the L1 and L2 terminals can come from V1 and V2
100 mA fuses on L1 and L2
480V Power Supply
Connect one phase to the L1 terminal and the other phase to the L2 terminal. You can use the same wires from the grid that the voltage inputs use (see diagram above).
The power supply G (ground) terminal must be connected to the same point as the meter 
terminal.
Protective Fuses
The 480V power supply requires 100 mA fuses on the L1 and L2 terminals. These should be IEC type T slow blow fuses.
NOTE
100 mA fuses can be shared with the voltage inputs.
Powering Up the Meter
After the power supply is attached to the meter, and its wiring is connected:
1.Reconnect and energize all wiring that was disconnected when the meter was prepared for power supply installation.
2.Power up the meter and verify correct operation.
