Wiring

Wiring regulations on wire diameters differ from country to country. Please refer to your LOCAL

ELECTRICAL CODES for field wiring rules. Be sure that installation is complied with such rules and

regulations.

General Precautions

• Ensure that the rated voltage of the unit corresponds to the nameplate before carrying out proper wiring

according to the wiring diagram.

• Provide a power outlet to be used exclusively for each unit. A power supply disconnect and a circuit

breaker for over current protection should be provided in the exclusive line.

• All wiring must be GROUNDED to prevent possible hazards due to insulation failures.

• All wiring must be firmly connected.

• All wiring must not come in contact with the hot refrigerant piping, compressor or any moving parts of fan

motors.
