Wire Selection for High‑Voltage Inputs

Connection to the mains terminals shall be made with 14 AWG (1.63 mm) minimal wire gauge THHN 600VAC rating.

All high voltage input wires shall be routed through the high voltage conduit entry and do not mix with other low voltage wiring.

Any unused high voltage conduit holes shall be plugged securely with supplied "safety cap". Wiring to these terminal blocks shall be tightened to 3.54lb.-in torque.

*Please note that there are two voltage inputs (Vin1 and Vin2) for 12-load and 48-load power meter but only one voltage input (Vin1) for a 3-load power meter.

Each voltage inputs contain up to four leads, namely L1, L2, L3, and N (neutral) which can be configured by software to measure up to three phases voltage signal with respect to N (neutral). Vin1 L1 and L2 are also connected to meter's 80-600V wide input power supply to power the meter. When installing a 12 or 48 load power meter, Vin1 must be used to power the unit. The meter will not power off Vin2.
