● Be sure to turn off the power supply before dissembling or
assembling the operation keypanel and fixing the front cover to avoid
bad contact causing faults or non-display of the operator.
● Do not install the inverter in a space with explosive gas to avoid the
risk of explosion.
● If the inverter is used at or above 1000m above seal level, the cooling
efficiency will be worse, so please run it by de-rating.
● Do not install any contactor and other components of capacitor or
varistor on the output side of the inverter. Otherwise it will cause
malfunctions and damages of components of the inverter.
● Do not install any switch component like air circuit breaker or
contactor at the output of the inverter. If any of such components
must be installed because of the requirements of process and
others, it must be ensured that the inverter has no output when the
switch acts. In addition, it is forbidden to install any capacitor for
improvement of power factor or any varistor against thunder at the
output. Otherwise it will cause malfunctions, tripping protection and
damages of components of the inverter. Please remove them as shown
in the below diagram.
● It will affect the service life of the inverter if a contact is connected
to the front end of input of the inverter to control its starts and stops.
Generally it is required to control it through FOR or REV terminals.
Special attention should be paid to its use in the case of frequent
starts and stops.
● Please use an independent power supply for the inverter. Do avoid
using the common power supply with an electrical welder and other
equipment with strong disturbance. Otherwise it will cause the
protection or even damage of the inverter.
