3.2.3 Wiring Method
Wiring method
(1) Remove a portion of the wire's insulation.
(2) Insert wire into terminal hole until it stops. Tighten screw clockwise to fix wire in place.
(The tightening torque: 0.22 to 0.25 N·m (2.3 to 2.5 kgf·cm))
Precautions on wiring
The following precautions should be observed, to avoid broken or disconnected wires.
When removing the wire's insulation, be careful not to scratch the core wire.
Do not twist the wires to connect them.
Do not solder the wires to connect them. The solder may break due to vibration.
After wiring, make sure stress is not applied to the wire.
In the terminal block socket construction, if the wire is fastened upon counter-clockwise
rotation of the screw, the connection is faulty. Disconnect the wire, check the terminal hole,
and then re-connect the wire.
