Notes :
1. Voltage range
Voltage supplied to the unit terminals should be within the
minimum and maximum range
2. Maximum allowable voltage unbalance between phase is 2 %
3. MCA / MOP
MCA = (1.25 x Load1) + Load2 + Load3
MOP = (2.25 x Load1) + Load2 + Load3
- Load1 : Rated running current of largest motor
(compressor or other motor)
- Load2 : sum of current for all other motors
- Load3 : any other load rated 1.0A or more
4. Select wire spec. based on the MCA
5. Recommended circuit breaker is ELCB (Earth Leakage circuit
breaker)
6. MSC & RLA are measured as the compressor only test
condition.
7. MSC values
Min.: 198
Max.: 264
Min.: 352
Maxi.: 457
22.45 39.45 14.20 17.00 0.24 1.20
26.20 46.20 14.20 20.00 0.24 1.20

8.59 14.50 5.91 5.91 0.24 1.20
8. RLA is measured during each individual compressor test
condition.
9. OFM is measured as the outdoor unit test condition
(Example) Selection of proper circuit breaker
① Model : AUUW486D
- Rated running current : 20.0A (refer to spec. sheet)
② MCA = (1.25 x Load1) + Load2 + Load3
= (1.25 x 20.0) + 0 + 1.20 = 26.2A
③ MOP = (2.25 x Load1) + Load2 + Load3
= (2.25 x 20.0) + 0 + 1.20 = 46.2A
→ Finally select circuit breaker 50A
MCA : Minimum Circuit Amperes (A)
MOP : Maximum rating over current protective device
MSC : Maximum Starting Current
RLA : Rated Load Amperes (A)
OFM : Outdoor Fan Motor
kW : Fan Motor rated output (kW)
FLA : Full Load Amperes (A)
