How to connect wiring to the terminal
a) For Indoor Unit
(1) Cut the wire end with a cutting pliers, then strip the insulation to
expose the wire about 7 mm. See the label (Fig. 26) near the ter-
minal plate.
(2) Using a screwdriver, loosen the terminal screw on the terminal
plate.
(3) Insert the wire and tighten the terminal screw completely using a
screwdriver.
b) For Outdoor Unit
�
For solid core wiring (or F-cable)
(1) Cut the wire end with a cutting pliers, then strip the insulation to
expose the solid wire about 25 mm. (Fig. 27)
(2) Using a screwdriver, remove the terminal screw(s) on the terminal
plate.
(3) Using the pliers, bend the solid wire to form a loop suitable for the
terminal screw.
(4) Shape the loop wire properly, place it on the terminal plate and fix
it securely with the removed terminal screw using a screwdriver.
�
For stranded wiring
(1) Cut the wire end with a cutting pliers, then strip the insulation to
expose the stranded wiring about
10 mm and tightly twist the wire ends.
(Figs. 28 and 29)
(2) Using a 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 connector. (Fig. 28)
