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. (Fig. 4-7)
(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.
(4) Place the ring pressure terminal, and
replace and tighten the removed terminal
screw using a screwdriver. (Fig. 4-8)
■ examples of shield wires
(1) Remove cable coat not to scratch braided shield. (Fig. 4-9)
(2) Unbraid the braided shield carefully and twist the
unbraided shield wires tightly together. Insulate the shield
wires by covering them with an insulation tube or wrapping
insulation tape around them. (Fig. 4-10)
(3) Remove coat of signal wire. (Fig. 4-11)
(4) Attach ring pressure terminals to the signal wires and the
shield wires insulated in Step (2). (Fig. 4-12)

The power inlet port is located at the rear.
The remote control wiring inlet port is located at the rear (for
use with the wired remote controller). For details, refer to
Fig. 3-3.
(2) How to carry out wiring
● Insert the power wiring into the indoor unit through the
rubber at the side of the electrical component box.
● For wiring connection to the outdoor unit and remote
control wiring, open the elongated hole of the piping cover
and pass the wires through the hole.
