1 . Before supplying power to the product, measure the grounding resistance of power terminal (3 phases: R,S,T,N/1 phase:
L,N) and outdoor unit by using a DV 500 V insulation resistance tester .
- Measured value should be 30 MΩ or above .
• Do not measure the communication terminal as the communication circuit of it can be damaged .
• Check whether the communication terminal becomes short circuit by using a circuit tester .
CAUTION
