CAUTION
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.
CAUTION
Do not perform dismantling or checks while power supply and charging indicator” CHARGE” are still on.
During check and maintenance
CAUTION
Ambient temperature for operating the inverter shall be -10
℃
to + 40
℃
and 90%RH non moistring
condensation.
CAUTION
After removing the dust-cover, ambient temperature for operating the inverter shall be -10
℃
to + 50
℃
and
95%RH non moistring condensation. However under this condition, the ambient environment 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.
During rejection
CAUTION
Explosion may occur when burning the electrolytic capacitor of the main circuit and printing plate. Toxic gas
may be generated when burning control panel and other plastic fittings.
It shall be treated as Industrial waste.
