To install the control voltage cable in a 208Y/120V or 120/240V application:
NOTE: If the circuit breaker panel does not designate phase A, phase B and phase
C feeds, make your own designation and use it for the rest of the installation.
1. Before connecting the sense voltages, turn off the power to the circuit being
connected.
2. Always use a properly rated voltage sensing device to confirm power is off.
3. Connect the sense voltages phase A, B, C, and N leads from the voltage
disconnect to the meter as described in Figure 5 on page 13 and Figure 6 on
page 14.
NOTE: The phase wiring sequence A, B, C between the PowerLogic EM4000
meter and the panel must match or the measurement readings will be wrong.
4. If more than one meter is being installed, repeat this procedure for each
additional meter.
