Manufacturer’s recommended specifications of the circuit breaker
and power cable
1. Basic model
2. Electric Specification
• The relationship between the starting time and the starting current
(Digital Scroll Comp. + Fixed Scroll Comp)
• Voltage range
Units are suitable for use on electrical systems where voltage supplied to unit terminal is not
below or above listed range limits.
• Maximum allowable voltage variation between phases is 2%.
Abbreviations
- MCA: Min. Circuit Amps. (A)
MCA = 1.25 X LOAD1 + LOAD2
( LOAD1: RLA of Fixed Comp. / LOAD2: RLA of Digital Comp. + FLA of Fan Motor)
- RLA: Rated Load Amps. (A)
- OFM: Outdoor Fan Motor

• Install a circuit breaker. For safety and maintenance, we strongly recommend that
MCCB, ELB and ELCB have to be installed every outdoor unit.
- ELCB : Earth Leakage Circuit Breaker
- MCCB : Molded Case Circuit Breaker
- ELB : Earth Leakage fuse Breaker
• Operate the unit after the refrigerant piping work must be done.
• Do not disassemble or alter the wiring of the unit during the electrical wiring work.
If not, the unit may be damaged.
