3-2-3 Wiring Control Circuit Terminals

The control signal line must be 50 m or less and must be separated from
the power line. If frequency references are input externally, use a twisted-
pair shielded line.
H Wiring Sequence Input/Output Terminals
Wire the sequence input terminals (SF, SR, S1, and SC) and the multi-function contact
output terminals (MA, MB, and MC) as described below.
D Wires to be Used
Wire type
Single wire
Stranded wire
D Wiring Method
•Wire each terminal as follows:
a) Loosen the terminal screw with a thin-slotted screwdriver.
b) Insert the wire from underneath the terminal block.
c) Tighten the terminal screw firmly.
•Always separate the control signal line from the main circuit cables and other power
cables.
