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.
