in unit malfunction. A fire hazard may also occur. Therefore,
ensure that all wiring is tightly connected.
When connecting each power wire to the terminal, follow the
instructions on “How to connect wiring to the terminal” and
fasten the wire securely with the terminal screw.
How to connect wiring to the terminal
