¢ Precaution
Regulations for wire diameter and selecting circuit breaker size differ from locality.
Always install in accordance with local standard.
WARNING
• Do not turn on the power until all installation work is complete.
• Before starting work, check the power is not being supplied to the unit.
• Connect the connection cable firmly to the terminal board. Imperfect installation may cause fire.
• Always install a circuit breaker for each power supply circuit. Failure to use a circuit breaker
could result in electrical shock or fire.
• Always install a disconnect switch for each power supply circuit.
• Always connect the ground wire.
• Always fasten the outside covering of the connection cable with the cord clamp. (If the insulator
is chafed, electric leakage may occur.)
• Never install a condenser for improve the power factor. (It will not improve the power factor and
the condenser will become abnormally hot.)
• When installing this system in high humidity locations, install using Ground Fault Equipment
Breaker (GFEB) to reduce the risk of leaking current which may result in electric shock or poten-
tial fire.
