VLT 7000 Boosterprotection
• Electronic motor thermal protection against overload.
• Temperature monitoring of heat-sink ensures that the frequency converter cuts out if the temperature reaches
90°C. An overtemperature can only be reset when the temperature of the heat-sink has fallen below 60°C.
• The frequency converter is protected against short-circuiting on motor termi
