(for low voltage line)

(3) Pass the connecting cable through the hole.
(4) Properly connect the cable on the terminal block.
(5) Fix the connection cable with cord clamp provided on the unit

not to have strain at the terminal when the connection cable is
pulled outside up to a 35 pound weight.

(6) Wind the vinyl tape round the connecting cable for sealing

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

terminal plate.

(3) Using a round terminal fastener or pliers, securely clamp

each stripped wire end with a round terminal.
