(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 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
(6) Maintenance, inspection and parts replacement
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.
Many of the diagrams and drawings in this Instruction
Manual (basic) show the inverter without a cover, or partially
open. Never operate the inverter in this manner. Always
replace the cover and follow this Instruction Manual (basic)
when operating the inverter.
