ELECTRICAL CONNECTIONS
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.
