Safeguards:
• Electronic thermal motor protection against overload.
• Temperature monitoring of the power module ensures that the adjustable frequency drive cuts
out if the temperature reaches 212 °F (100 °C). An overload temperature cannot be reset until
the temperature of the power module is below 160 °F (70 °C).
• The frequency converter is protected against short-circuits on motor terminals U, V, W.
• If an electrical phase is missing, the variable frequency drive will cut out.
• Monitoring of the intermediate circuit voltage ensures that the variable frequency drive cuts out
if the intermediate circuit voltage is too low or too high.
• The variable frequency drive is protected against ground fault on motor terminals U, V, W.
