9200 Power Supply Retrofit Instructions Wiring 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 meterterminal.

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.
