Installation 4. Wiring Diagram
3-phase 4-wire type: Direct input
①Auxiliary power supply
AC100 to 240V or DC100 to 240V.
②Fuses 0.5A
③Some MODBUS®RTU equipment doesn't have SG. In this case, the wiring between SG is unnecessary.
Note 1: For low voltage circuits, grounding the secondary side of VT and CT is not t necessary.
