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 circuit. Insuffi-
cient capacity of the power supply circuit or improper electri-
cal 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.

•

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.

•

Multiple number of indoor units 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 legis-
lation.

•

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 light-
ning bolt.

•

Do not turn on the power supply (branch switch, branch over-
current breaker) until all the works are finished.

•

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.

WIRING CONNECTION METHOD

<<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 circuit 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 insu-
lation.

•

If the above is not available, make sure to observe the follow-
ing items.

•

2 wirings of different sizes to the terminal block for power
supply is prohibited.
