Check points on wiring
1) Electrical or mechanical interlock of MC1 and MC2 is required for Inverter
Bypass Operation. Otherwise, chattering may occur or input power may flow to
inverter output, damaging the inverter.
2) Make the sequence to disable the Auto restart after power failure if required.
Otherwise, inverter will be automatically restarted.
3) Do not apply the voltage directly to control circuit input terminals such as FX, RX
.
