9-4 WIRING CONNECTION METHOD
CAUTION FOR WIRING
• For connection to the terminal block, use ring type crimp
style terminals with insulation sleeve or insulate the wirings
properly.

style terminals
Fig. 21
• Connect the terminal as shown in Fig. 22.
• Do not carry out soldering finish when stranded wires are
used. (Otherwise, the loosening of wires may result in
abnormal heat radiation.)
Use wires the same in size
(If the air conditioner is
in simultaneous multi operation)
Fig. 22
(Abnormal heating may occur if the wirings are not tight-
ened securely.)
• Use the required wirings, connect them securely and fix
these wirings securely so that external force may not apply
to the terminals.
• Use a proper screw driver for tightening the terminal
screws.
If an improper screw driver is used, it may damage the
screw head and a proper tightening cannot be car ried out.
• If a terminal is over tightened, it may be damaged.
Refer to the table shown below for tightening torque of
terminals.
