VLT ® 2900 Series Safeguards: • Electronic thermal motor protection against overload. • Temperature monitoring of the power module ensures that the frequency converter cuts out if the temperature reaches 100 °C. An over- load temperature cannot be reset until the temperature of the power module is below 70 °C. • The frequency converter is protected against short-circuits on motor terminals U, V, W. • If a mains phase is missing, the frequency converter will cut out. • Monitoring of the intermediate circuit voltage ensures that the frequency converter cuts out if the intermediate circuit voltage is too low or too high.
• The frequency converter is protected against earth fault on motor terminals U, V, W. 82 MG.29.A3.02 - VLT ® is a registered Danfoss trademark
