*Indicates wiring for a balanced system
NOTE:
•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.

Power system
This section outlines typical requirements for wiring the voltage and current inputs of the meter to the electrical power system.
For wiring instructions and safety precautions, see the meter installation sheet that was shipped with your meter, or download a copy at
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
If your system voltage is greater than the specified direct connect maximum voltage, you must use VTs (voltage transformers) to step down the voltages.
