Use shielded wires for inter-unit control
wiring (c) and ground the shield on both
sides, otherwise misoperation from noise may
occur. (Fig. 5-4)
All wiring except inter-unit control wiring (c)
has polarity.
Connect wiring as shown in Section 5-3
“Wiring System Diagrams”.

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 correspond-
ing 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. (Fig. 5-5)
(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 connec-
tor.
(4)
Place the ring connector wire, and replace and
tighten the removed terminal screw using a
screwdriver. (Fig. 5-6)
