in unit malfunction. A fire
hazard may also exist.
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 plate.
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 about 3/8 in.
and tightly twist the wire ends. (Fig. 5-5)
(2) Using a Phillips head screwdriver, remove the terminal
screw(s) on the terminal plate.
(3) Using a ring connector fastener or pliers, securely
clamp each stripped wire end with a ring pressure
terminal.
(4) Place the ring pressure terminal, and replace and
tighten the removed terminal screw using a screwdriver.
