ELECTRIC WIRING WORK
8-1 GENERAL INSTRUCTIONS
• Make certain that all electric wiring work is carried out by
qualified personnel according to the applicable legislation
and this installation manual, using a separate dedicated cir-
cuit.
Insufficient capacity of the power supply circuit or improper
electrical construction may lead to electric shocks or a fire.
• Make sure to install an earth leakage breaker.
Failure to do so may cause electrical shocks and a fire.
• Do not turn on the power supply (branch switch, branch over-
current breaker) until all the works are finished.
• Multiple number of indoor unit are connected to one outdoor
unit. Name each indoor unit as A-unit, B-unit ..... and the like.
When these indoor units are wired to the outdoor unit and the
BS unit, always wiring the indoor unit to the terminal indi-
cated with the same symbol on the terminal block. If the wir-
ing and the piping are connected to the different indoor units
and operated, it will result in malfunction.
• Make sure to earth the air conditioner. Earthing resistance
should be according to applicable legislation.
• Do not connect the earth wiring to gas or water piping, light-
ning conductor or telephone earth wiring.
• Gas piping ............ Ignition or explosion may occur if the
gas leaks.
• Water piping ......... Hard vinyl tubes are not effective
earths.
• Lightning conductor or telephone earth wiring .................
............................. Electric potential may rise abnormally
if struck by a lightning bolt.
• For electric wiring work, refer to also the "WIRING DIA-
GRAM" attached to the control box lid.
• Carry out wiring between the outdoor units, indoor units and
the remote controllers according to the wiring diagram.
• Carry out installation and wiring of the remote controller
according to the "installation manual" attached to the remote
controller.
• Do not touch the Printed Circuit Board assembly. It may
cause malfunction.

8-4 WIRING CONNECTION METHOD
(Refer to Fig. 38)
CAUTION FOR WIRING
• The indoor units in the same system can be connected to the
power supply from one branch switch.
However, selection of branch switch, branch over current breaker
and wiring size must be according to applicable legislation.
• For connection to the terminal block, use ring type crimp
style terminals with insulation sleeve or treat the wiring
with insulation. (Refer to Fig. 36)
Ring type crimp style terminal
• If the above is not available, make sure to observe the fol-
lowing items.
(Abnormal heating may occur if the wiring are not tight-
ened securely.)
Connection of 2
wirings of same
size must be
carried out on both

• Use the required wiring, connect them securely and fix these
0.5
wiring so that external force may not apply to the terminals.
1.1
• 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 carried out.
