Safeguards:
• Electronic thermal motor protection against overload.
• Temperature m onitoring of the power module ensures that the frequency converter cuts
out if the temperature reaches 100 °C . An overload temperature cannot be reset unt il 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 freque ncy converter w ill 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 freque n cy converter is p rotected against earth fault on motor terminals U, V, W.
