Notes :
1. Voltage range
Voltage supplied to the unit terminals should be within the mini-
mum 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 condi-
tion.
7. MSC values
10/28 : MSC of (inv. comp.) / (const. comp.)
8. RLA is measured during each individual compressor test condi-
tion.
Ex) 7.0/8.2 : RLA of (inv. comp.) / (const. comp.)
9. OFM is measured as the outdoor unit test condition
(Example) Selection of proper circuit breaker
Model : AUUW126B
- Rated running current : 6.5 A (refer to spec. sheet)
MCA = (1.25 x Load1) + Load2 + Load3
= (1.25 x 6.5) + 0 + 0 = 8.13 A
MOP = (2.25 x Load1) + Load2 + Load3
= (2.25 x 6.5) + 0 + 0 = 14.6 A
→
Finally select circuit breaker 15A(Min. circuit breaker is 15A)
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)
