[FM56AH U32]
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*RLA)+load1+load2
MOP = (2.25*RLA)+load1+load2
- Load1 : sum of current for all other motors
- Load2 : 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.

9. RLA is measured during each individual compressor test
condition.
10. OFM is measured as the outdoor unit test condition
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)
