Meter wiring
For wiring instructions and safety precautions, see the meter installation sheet that was
shipped with your meter, or download a copy at www.schneider-electric.com.
• Wire connections to the meter’s voltage inputs, control power, digital output, and RS-
485 communications are terminated using the supplied pluggable wire connectors.
• When wiring the meter’s current inputs, terminate the wire ends with ring or split-ring
crimp connectors.
Use the meter installation sheet when wiring the meter.
