Protection and Features:
Electronic thermal motor protection against overload.
•
• Temperature monitoring of the heatsink ensures that the adjustable frequency drive trips if the
temperature reaches 203°F ± 9°F [95 °C ± 5°C]. An overload temperature cannot be reset
until the temperature of the heatsink is below 158°C ± 9°C [70°C ± 5°C] (Guideline - these
temperatures may vary for different power sizes, enclosures, etc.).
The adjustable frequency drive is protected against short circuits on motor terminals U, V, W.
•
If a line phase is missing, the adjustable frequency drive trips or issues a warning (depending on the load).
•
• Monitoring of the intermediate circuit voltage ensures that the adjustable frequency drive
trips if the intermediate circuit voltage is too low or too high.
The adjustable frequency drive is protected against ground faults on motor terminals U, V, W.
