error
All stop
Communication is disrupted
between IPDUs (P.C.
boards) in inverter box.
• Check wiring and
connectors involved in
communication between
IPDU-I/F P.C. board for
bad contact or broken wire.
• Check for defect in outdoor
P.C. board (I/F, A3-IPDU
or Fan IPDU).
• Check for external noise.
