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.
