Protection and Features:
•
Electronic thermal motor protection against overload.
•
Temperature monitoring of the heatsink ensures that the 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.
•
The frequency converter is protected against short-circuits on motor terminals U, V, W.
•
If a mains phase is missing, the frequency converter trips or issues a warning.
•
Monitoring of the intermediate circuit voltage ensures that the frequency converter trips if the
intermediate circuit voltage is too low or too high.
•
The frequency converter is protected against earth faults on motor terminals U, V, W.
