CAUTION
• When conducting wiring work, do not touch the printed circuit
board. It may cause failure.
• Never connect the power supply wiring to the terminal block
for remote controller/transmission wiring. It may damage the
total system.
• Do not connect the remote controller/transmission wiring to
the wrong terminal block.
• In case the piping penetration cover is cut off and used as
wiring penetration hole, after the wiring connection is fin-
ished, mend the cover.
• Seal the clearance around the wirings with putty and insulat-
ing material (field supply).
(If insects and small animals get into the indoor unit, short cir-
cuiting may occur inside the control box.)
• If the low voltage wiring (remote controller wiring) and the
high voltage wiring (power supply wiring, earth wiring) are
brought into the indoor unit from the same place, they may be
affected by electric noise (outside noise) and cause malfunc-
tion or failure.
• Keep the distance of 50mm or more between the low voltage
wiring (remote controller wiring) and the high voltage wiring
(power supply wiring, earth wiring) at anywhere outside the
indoor unit. If both the wirings are laid down together, they
may be affected by electric noise (outside noise) and cause
malfunction or failure.

(1) Install the fixture at the wiring entrance side.
(2) Fix the wiring to the fixture by clamps so that no tension will
be given to the terminal connection.
(3) To avoid the loosing of the power supply wiring and Earth
wiring, band the clamp to tightly fit the fixture at terminal
block side.
