VLT 6000 HVAC protection:
•
•
•
•
•
Electronic motor thermal protection against overload.
•
•
•
•
•
Temperature monitoring of heat-sink ensures that the VLT frequency converter cuts out if the temperature
reaches 90°C for IP 00 and IP 20. For IP 54, the cut-out temperature is 80°C. An overtemperature can only
be reset when the temperature of the heat-sink has fallen below 60°C.
•
•
•
•
•
The VLT frequency converter is protected against short-circuiting on motor terminals U, V, W.
•
•
•
•
•
The VLT frequency converter is protected against earth fault on motor terminals U, V, W.
•
•
•
•
•
Monitoring of the intermediate circuit voltage ensures that the VLT frequency converter cuts out if the
intermediate circuit voltage gets too high or too low.
•
•
•
•
•
If a motor phase is missing, the VLT frequency converter cuts out.
•
•
•
•
•
If there is a mains fault, the VLT frequency converter is able to carry out a controlled deramping.
•
•
•
•
•
If a mains phase is missing, the VLT frequency converter will cut out when a load is placed on the motor.
