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 outputs, digital (status) inputs 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.

Direct connect voltage limits

You can connect the meter’s voltage inputs directly to the phase voltage lines of the power system if the power system’s line-to-line or line-to-neutral voltages do not exceed the meter’s direct connect maximum voltage limits. The meter's voltage measurement inputs are rated by the manufacturer for up to 400 V L-N / 690 V L-L. However, the maximum voltage allowed for direct connection may be lower, depending on the local electrical codes and regulations. In US and Canada the maximum voltage on the meter voltage measurement inputs may not exceed 347 V L-N / 600 V L-L.

If your system voltage is greater than the specified direct connect maximum voltage, you must use VTs (voltage transformers) to step down the voltages.
