(4) Connect the remote controller wiring led from the routing
hole to the terminals (P1 and P2) of the terminal block
(X1M: 4P). (There is no polarity.)
After this is done, use the wiring fixture (11) and clamp (4)
attached to bind the wiring without applying tension to the
connecting section of the wirings.

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 panel and cause electric shocks or a fire.

and Earth wiring
• 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 (transmission 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
(transmission 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.
