Arrangement of control terminal

Wires connection
For the control circuit wiring, strip off the sheath of a cable, and use it with a blade terminal. For a single wire, strip off
the sheath of the wire and apply directly.
Please insert a blade terminal or a single wire into the terminal for wiring.
(1) Strip off the sheath for the below length. If the length of the sheath peeled is too long, a short circuit may occur
with neighboring wires. If the length is too short, wires might come off.
Wires should be well connected to avoid messiness. In addition, don’t need to solder it.
