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.

The meter’s voltage inputs must be wired to fuses/breakers and a disconnect switch. If 
using a voltage transformer (VT), both primary and secondary sides of the VT must be 
wired to fuses/breakers and disconnect switches.

•

Clearly label the device’s disconnect circuit mechanism and install it within easy reach 
of the operator.

•

The fuses / circuit breakers must be rated for the installation voltage and sized for the 
available fault current.

•

Fuse for neutral terminal is required if the source neutral connection is not grounded.

See the meter installation sheet for fuse ratings.

For all connected current inputs, use a CT shorting block to short-circuit the secondary 
leads of the CTs before removing the current input connections to the meter.

Ground any unused current inputs.
