8.2 Other 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 on motor terminals U, V, W.
• If a motor phase is missing, the frequency 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.
