D Wires to be Used
Always use twisted-pair shielded wires to prevent malfunctions due to noise.
Wire type
Single wire
Stranded wire
Wire size
0.5 to 1.25 mm2
0.5 to 1.25 mm2
Wire to be used
Polyethylene-insulated cable for
instrumentation (with shield)
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.
