Danfoss VLT 6000 HVAC Series User Manual

NB!
VLT 6002-6072, 525-600 V units do not
comply with EMC, Low Voltage or PELV
directives.
VLT 6000 HVAC protection
• Electronic motor thermal protection against overload.
• Temperature monitoring of heat-sink ensures that the frequency converter cuts out if the temperature reaches
90°C for IP00, IP20 and NEMA 1. For IP54, 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.
For the units mentioned below, the limits are as follows:
- VLT 6152, 380-460 V, cuts out at 75° C and can be reset if the temperature is below 60 °C.
- VLT 6172, 380-460 V, cuts out at 80° C and can be reset if the temperature has fallen below 60° C.
- VLT 6222, 380-460 V, cuts out at 95° C and can be reset if the temperature has fallen below 65° C.
- VLT 6272, 380-460 V, cuts out at 95° C and can be reset if the temperature has fallen below 65° C.
- VLT 6352, 380-460 V, cuts out at 105° C and can be reset if the temperature has fallen below 75° C.
- VLT 6402-6602, 380-460 V cuts out at 85° C and can be reset if the temperature has fallen below 60° C
- VLT 6102-6152, 525-600 V, cuts out at 75° C and can be reset if the temperature has fallen below 60° C.
VLT 6172, 525-600 V, cuts out at 80° C and can be reset if the temperature has fallen below 60° C.
VLT 6222-6402, 525-600 V, cuts out at 100° C and can be reset if the temperature has fallen below 70° C.
VLT 6502-6652, 525-600 V, cuts out at 75° C and can be reset if the temperature has fallen below 60° C.
• The frequency converter is protected against short-circuiting on motor terminals U, V, W.
• The frequency converter is protected against earth fault on motor terminals U, V, W.
• Monitoring of the intermediate circuit voltage ensures that the frequency converter cuts out if the intermediate
circuit voltage gets too high or too low.
• If a motor phase is missing, the frequency converter cuts out.
• If there is a mains fault, the frequency converter is able to carry out a controlled decelleration.
• If a mains phase is missing, the frequency converter will cut out or autoderate when a load is placed on the
motor.
