1-phase 2-wire system, With VT

①

Auxiliary power supply
100 to 240 V AC or 100 to 240 V DC

②

Fuse (recommendation)

Rated current: 0.5 A, Rated breaking capacity: 250 V AC 1,500 A / 250 V DC 1,500 A (a UL certified product)

③

If MODBUS RTU devices do not have the SG terminal, the wiring between SG terminals is not necessary.

④

Install 120-Ohm terminating resistors between terminals

‘T/R+’ and ‘T/R-‘ for devices at both ends of MODBUS RTU

communication line.

*Note1: For low voltage circuits, it is not necessary to ground the VT and CT secondary sides.

*Note2: Do not connect the NC terminal.
