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. Select proper circuit breaker as given below
MCA < Circuit breaker MOP
6. Recommended circuit breaker is ELCB (Earth Leakage circuit
breaker)
7. MSC & RLA are measured as the compressor only test
condition.
8. MSC values
23.1/14.0 : MSC of (inv. comp.) / (const. comp.)
9. RLA is measured during each individual compressor test
condition.
Ex) 6.1/7.0 : RLA of (inv. comp.) / (const. comp.)
10. OFM is measured as the outdoor unit test condition
(Example) Selection of proper circuit breaker
Model : A2UW146FA0 [FM14AH UE0]
- Rated running current : 5.8 A (refer to spec. sheet)
MCA = (1.25 x Load1) + Load2 + Load3
= (1.25 x 5.8) + 0 + 0 = 7.25 A
MOP = (2.25 x Load1) + Load2 + Load3
= (2.25 x 5.8) + 0 + 0 = 13.05 A
Finally select circuit breaker 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
