Is the measured insulation resistance
correct?
Action
Yes
Continue with the next step.
No
Replace the reactor, see

Measure the resistance of the reactor.
Result:
The measured resistance MUST be 105.3~128.7 mΩ.
Is the resistance measurement correct? Action
Yes
Return to the troubleshooting of the
specific error and continue with the
next step.
