fire hazard may also exist. Therefore, be sure
all wiring is tightly connected.
When connecting each power wire to the corresponding terminal,
follow instructions "How to connect wiring to the terminals" and
fasten the wire tightly with the fixing screw of the terminal plate.
How to connect wiring to the terminals
For strand wiring
(1) Cut the wire end with a wire cutter or wire-cutting pliers,
then strip the insulation to expose the strand wiring about
10mm(3/8").
(2) Using a screwdriver, remove the terminal screw(s) on the
terminal plate.
(3) Using a round terminal fastener or pliers, securely clamp
each stripped wire end with a round terminal.
(4) Position the round terminal wire, and replace and tighten
the terminal screw using a screwdriver.
