9. ELECTRIC WIRING WORK
WIRING INSTRUCTIONS
•
Electric wiring work must be conducted by electrician authorized by power companies. (Only licensed
electrician can conduct electric work and earth connections.)
• All wiring must be performed by an authorized electrician.
•
Be sure to install an earth leakage breaker to the outdoor unit.
(This installation of an earth leakage breaker is mandatory for the prevention of electric shocks and fire
disasters.)
•
Install the earth leakage breaker which can handle harmonics.
(This unit has an inverter, so an interrupter capable of handling high frequencies is needed to prevent
malfunction of the interrupter itself.)
• Be sure to use earth leakage breaker dedicated for earth leakage protection in combination with the load
break switch with fuse or breaker for wiring.
• Make sure that 230V is specified wiring between the indoor and outdoor units and between indoor units.
• Do not turn on the power supply (of the indoor unit) until all the installation work is completed.
•
Be sure to earth the air conditioner.
•
Do not connect the earth wire to gas pipes, plumbing pipes, lightning rods, or telephone earth wires.
• Gas pipes: might cause explosions or fire if gas leaks.
•
Plumbing: no earth effect if hard vinyl piping is used.
•
Telephone earth wires or lightning rods: might cause abnormally high electric potential in the earth
during lighting storms.
• The earth is needed in order to reduce the noise generated by the unit’s inverter and influence on other
appliances and to release the charge built up in the product box by leaked current.
• For electric wiring work, refer to also “WIRING DIAGRAM” attached to the unit body.
• Never connect the power supply wire to the terminal block for remote controller wire, or otherwise the entire
system may be damaged.
•
For remote controller wiring details, refer to the installation manual attached to the remote controller.
• Do not touch the printed circuit board ASSY during the wiring work. Otherwise, it may cause damage.
