8. 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. Insufficient capacity of the power supply cir-
cuit 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.
• For electric wiring work, refer to also the “WIRING DIAGRAM” 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 indicated with the same symbol on the terminal block. If the wiring 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, lightning 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.
• Do not turn on the power supply (branch switch, branch overcurrent 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.
