Operation Methods
Connections
●Input
Connect to L1, L2, and L3 (for three-phase three-wire mode) or L1, L2, L3, and N (for three-phase four-wire
mode), depending on the mode selected using pin 2 on the DIP switch.
The Unit will not operate correctly if the DIP switch setting and the wiring do not agree.
Make sure the phase sequence is wired correctly. The Unit will not operate normally if the phase sequence
is incorrect.
●Outputs
Terminals 11, 12, and 14 are the output terminals for overvoltage (SPDT).
Terminals 21, 22, and 24 are the output terminals for undervoltage (SPDT).
* Use the recommended ferrules if you use twisted wires.
DIP Switch Settings
The Startup lock time, number of wires, and rated voltage are set using the DIP switch located on the bottom of the Unit.
