■
3-phase 4-wire system, Direct input
■
3-phase 4-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.
