Loose wiring may cause the
terminal to overheat or result in
unit malfunction. A fire hazard
may also exist. Therefore,
ensure that all wiring is tightly
connected.
When connecting each power wire to the corresponding
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 10 mm
and tightly twist the wire ends.
(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.
