7.4.4 Cautions Regarding Wiring
The following items should be observed, taking care not to cut or disconnect the wiring.
- 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 closes upon counter-clockwise
rotation, the connection is faulty. Disconnect the wire, check the terminal hole, and
then re-connect the wire.
