D Wires to be Used
Always use twisted-pair shielded wires to prevent malfunctions due to noise.
Wire type
Single wire
Stranded wire
D Wiring Method
•The wiring procedure is the same as for sequence input/output terminals, described
previously.
•Always separate the cables from the main circuit cables and other power cables.
•Connect the shield to the ground terminal of the Inverter. Do not connect to the control-
ler.
•Insulate the shield with tape to prevent it from coming into contact with other signal
lines and devices.
H Tightening Torque of Control Circuit Terminals
Tighten the control circuit terminals to the torque of 0.5 N S m which is the same torque
as for the M3 screws.
Note 1. Applying a torque of greater than 0.5 N S m may damage the terminal block.
Note 2. If the tightening torque is insufficient, wires may be disconnected.
