Device Connections

The 56WM is compatible with shunted current transformers with a 0.333V output only. Serious
shock hazard and device damage may occur if unshunted current transformers are used.
When making connections with stranded wire, use ferrules on all terminal block sensor connections.

2.3.1 Voltage Connections

Connect the voltage phase conductors L1, L2, L3, N as necessary to the 56WM. The minimum
conductor is 14 AWG, THHN, 600VAC. The neutral connection on the 56WM must always be
connected to either the neutral or ground conductor of the load to ensure accurate measurements.
See Figure 2-1.
