assembling the operation keypanel and xing 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
efciency 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

Protection
Functions
Electronic thermal motor protection against overload.
Temperature monitoring of the heatsink ensures that the frequency
converter trips if the temperature reaches 95 °C ± 5°C. An overload
temperature cannot be reset until the temperature of the heatsink
is below 70 °C ± 5°C (Guideline - these temperatures may vary for
different power sizes, enclosures etc.).
The frequency converter is protected against short-circuits on motor
terminals U, V, W.
The frequency converter is protected against earth faults on motor
terminals U, V, W.
Monitoring of the intermediate circuit voltage ensures that the
frequency converter trips if the intermediate circuit voltage is too low
or too high.
If a motor phase is missing, the frequency converter may trip.
If mains fault occurs, the frequency converter will ramp down to stop
and issues a warning.
If a mains phase is missing, the frequency converter trips or issues a
warning (dependingon the load).
