9-1 HOW TO CONNECT WIRINGS
Connecting methods of wiring between indoor and outdoor units, earth wiring, and remote controller
wiring
•
Wiring between units and earth wire
Connect the wiring between units and earth wire that are drawn into the unit in step “5. INDOOR UNIT
INSTALLATION”. When doing this, tie the wiring between units and the earth wire using the included clamp
(small) (4) and then firmly secure using the included clamp (small) (4).
(Refer to Fig. 21)
•
Remote controller wiring (a remote controller is not necessary for the slave unit in the simultaneous oper-
ation system mode.)
Connect the remote controller wiring to the terminal blocks (P
1
and P
2
).
When doing this, firmly secure the remote controller wiring using the included clamp (small) (4).
(Refer to Fig. 21)
CAUTION
•
Arrange the electric wiring and firmly attach the control box lid.
(Caught electric wires and detachment of the control box lid may result in electrical shock or fire.)
•
After connecting the wiring, attach the putty or insulating material (field supplied) to the hole of the wiring
so as not to leave any gap and prevent entry of small creatures from outside.
•
Route the low voltage wires (remote controller wiring) 50mm or more away from the high voltage wires
(interconnecting wires between the indoor and outdoor units) and earth wire so that they may not pass
through the same place.
Otherwise electrical noise (external static) could cause mistaken operation or breakage.

In case of using the power
supply terminal together with
the other connecting wirings
Make sure to process
the insulation at the wire
terminal part properly so that
the terminals do not get in
contact each other.
