• 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 tightened
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.

Terminal for power supply 1.47 ± 0.14
Earth terminal 1.47 ± 0.14
• Do not carry out soldering when stranded wirings
are used.
WARNING
• When wiring, form the wirings orderly so that the control box
lid can be securely fastened. If the control box lid is not in
place, the wirings may come out or be sandwiched by the
box and the lid and cause electric shocks or a fire.
(1) Remove the control box lid.
