(5) Emergency stop
Provide a safety backup such as an emergency brake which will prevent the machine and equipment from hazardous conditions if
the inverter fails.
When the breaker on the inverter primary side trips, check for the wiring fault (short circuit), damage to internal parts of the inverter,
etc. Identify the cause of the trip, then remove the cause and power on the breaker.
When any protective function is activated, take the appropriate corrective action, then reset the inverter, and resume operation.

Do not carry out a megger (insulation resistance) test on the control circuit of the inverter.

Treat as industrial waste.
