■ Operation and Setting Methods
K8AB-PW
Connections
1. 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.
2. 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).
