NOTE
VLT 8002-8300, 525-600 V units do not comply
with EMC, Low Voltage or PELV directives.
VLT 8000 AQUA protection:
•
Electronic motor thermal protection against overload.
•
Temperature monitoring of heatsink ensures that the adjustable frequency drive cuts out if the
temperature reaches 90° C (194° F) for IP00/Chassis and IP20/NEMA 1. For IP54/NEMA 12, the
cut-out temperature is 80° C (176° F). An overtemperature can only be reset when the temperature
of the heatsink has fallen below 60° C (140° F).
For the units mentioned below, the limits are as follows:
- VLT 8151-8202, 380-480 V cuts out at 80° C (176° F) and can be reset if the temperature is below
60 °C (140° F).
- VLT 8252-8352, 380-480 V cuts out at 105 °C (221° F) and can be reset if the temperature has
fallen below 70° C (158° F).
