Safeguards:
•
Electronic thermal motor protection against overload.
•
Temperature monitoring of the power module ensures that the frequency converter cuts out if the temperature reaches 100 °C. An overload
temperature cannot be reset until the temperature of the power module is below 70 °C.
•
The frequency converter is protected against short-circuits on motor terminals U, V, W.
•
If a mains phase is missing, the frequency converter will cut out.
•
Monitoring of the intermediate circuit voltage ensures that the frequency converter cuts out if the intermediate circuit voltage is too low or too
high.
•
The frequency converter is protected against earth fault on motor terminals U, V, W.
