5.11 Notes on Control Circuit Wiring
● Terminal GND is the common terminal for analog signals, and SC is the common
terminal for digital signals. Do not ground these terminals. Shielded or twisted-pair
cables should be used for control circuit terminals wiring and must be separated
from the wiring of main circuit and high current circuits (including the control circuit of
200 V relay).
● Please strip the wire insulation for wiring of the control circuit, according to the di‐
mensions given below. Too long stripping may cause short circuit of adjacent wires;
too short stripping may lead to wires becoming loose.

● Disconnection of cables or damage of screws may cause incorrect operation if
screws are not fixed correctly.
