8-4 WIRING CONNECTION METHOD
CAUTION FOR WIRING
• The indoor units in the same system can be connected to the power supply from one branch switch. How-
ever, selection of branch switch, branch over current circuit breaker and wiring size must be according to
applicable legislation.
• For connection to the terminal block, use a ring type crimp style terminals with insulation sleeve or insulate
the wirings properly.
• If the above is not available, make sure to observe the following requirements.
(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.
• Do not carry out soldering finish 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 float up or be sandwiched by the box and the lid and cause electric
shocks or a fire.

method >
• Power supply wiring, earth wiring
Pull the wiring through the wiring penetrating hole (high voltage). After connecting the power supply wiring
to [L · N] on the power supply terminal block (X2M) and the earth wiring to the earth terminal, clamp them
near the terminal block using the attached clamp (4). (Refer to page 20)
• Remote controller wiring, transmission wiring
Pull the wiring through the wiring penetrating hole (low voltage). After connecting the remote controller wir-
ing to [P1 · P2] and the transmission wiring to [F1 · F2] on the terminal block (X1M), clamp them near the
terminal block using the attached clamp (4). (Refer to page 20)
Tightening torque (N·m)
Terminal block for remote controller and transmission wirings 0.88 ± 0.08
Terminal for power supply 1.47 ± 0.14
Earth terminal 1.47 ± 0.14
Insulation sleeve
Ring type crimp style terminals
Wiring
Connection of 2 wirings
of same size must be
carried out on both sides.
Connection of wirings of
different sizes is
prohibited.
Connection of 2 wirings
on one side is prohibited.
