(5) Emergency stop
(6) Maintenance, inspection and parts replacement
(7) Disposal
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 input 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. It will cause a failure.
Treat as industrial waste.
