WARNING Loose wiring may cause the terminal to overheat or result
in unit malfunction. A fire hazard may also exist. There- fore, be sure all wiring is tightly connected.
When connecting each power wire to the corresponding terminal, follow the instructions “How to connect wiring to the terminal” and fasten the wire securely tight with the fixing screw of the terminal plate.
How to connect wiring to the terminal
