8.2 General Specifications

Protection and features
•
Electronic thermal motor protection against overload.
•
Temperature monitoring of the heatsink ensures that the frequency converter trips in case of overtemperature.
•
The frequency converter is protected against short-circuits between motor terminals U, V, W.
•
If a motor phase is missing, the frequency converter trips and issues an alarm.
•
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 faults on motor terminals U, V, W.
