7-4 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, selec-
tion 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.

Wiring
• If the above is not available, make sure to fulll the following
requirements.
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.
(Abnormal heating may occur if the wirings are not tight-
ened securely.)
• Use the required wirings, connect them securely and x
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 nish 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 oat up or be sandwiched by the
box and the lid and cause electric shocks or a re.

• Power supply wiring, ground wiring
Pass the power supply wire through the attached insula-
tion tube (16) between the outlet of conduit and the power
supply terminal, and bind them together with the attached
clamp (4). (RefertoFig.23-2)
Use a pair of conduit mounting plates (17) to connect a
conduit to the unit as shown Fig.23-1. After connecting the
power supply wiring to [L
1
· L
2
] on the power supply terminal
block (X2M) and the ground wiring to the ground terminal,
clamp them near the terminal block using the attached
clamp (4). (RefertoFig.23-2)
Remote controller wiring, transmission wiring
Pull the wiring through the wiring penetrating hole (low volt-
age). 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Fig.23-2)
• After connecting the wiring, make sure to stick the sealing
material (Small) (13) to the wiring penetrating hole to pre-
vent water from entering the indoor unit. (RefertoFig.24)
CAUTION
• Never connect the power supply wiring to the terminal
block for remote controller/transmission wiring (X1M).
If may damage the total system.
• Do not connect the remote controller/transmission wir-
ing to the wrong terminal block.
