Loose wiring may cause the terminal to overheat or result 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 fixing screw of the terminal board.
How to connect wiring to the terminal
■ For stranded wiring
(1) Cut the wire end with cutting pliers, then strip the insulation
to expose the stranded wiring approx. 3/8 inch (10 mm) and
tightly twist the wire ends. (Fig. 4-3)
(2) Using a Phillips head screwdriver, remove the terminal
screw(s) on the terminal board.
(3) Using a ring connector fastener or pliers, securely clamp
each stripped wire end with a ring pressure terminal.
