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 overload 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.
