Check and maintenance
Never touch heat sink or discharging resistor since temperature may be very high.
Since it is easy to change running speed from low to a high speed, verify safe working range of
motor and machine before running.
Pay attention to relative settings before using the brake.
Do not check signals during running.
All parameters of the inverter have been preset at the factory according to line frequency. Do
not change the settings unnecessarily.
Do not perform dismantling or checks while power supply and charging indicator” CHARGE”
are still on.
Ambient temperature for operating the inverter shall be -10
℃
to + 40
℃
and 90%RH non
condensation.
After removing the dust-cover, ambient temperature for operating the inverter shall be -10
℃
to + 50
℃
and 95%RH non condensation. However under this condition, the ambient environ-
ment must be without drips of water or metal dust. If there are, the dust cover shall be refitted
and check whether ambient temperature is within -10
℃
to + 40
℃
simultaneously.
