Emergency stop
CAUTION:
E
● 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 the protective function is activated (i. e. the frequency inverter switches off with an
error message), take the corresponding corrective action as described in the inverter man-
ual, then reset the inverter, and resume operation.
Maintenance, inspection and parts replacement
CAUTION:
E
● Do not carry out a megger (insulation resistance) test on the control circuit of the inverter.
It will cause a failure.
Disposing of the inverter
CAUTION:
E
● Treat as industrial waste.
