Protection and Features
•
Electronic thermal motor protection against overload.
•
Temperature monitoring of the heat sink ensures that the frequency converter trips if the temperature reaches
95
°
C
±

°
C. An overload temperature cannot be reset until the temperature of the heat sink is below 70

°
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.
•
If a mains phase is missing, the frequency converter trips or issues a warning (depending on the load).
•
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 (ground) faults on motor terminals U, V, W.
