Ce Compliance - Danfoss VLT AutomationDrive FC 300 Design Manual

Electrical Installation
If fuses/Circuit Breakers according to recommendations are
chosen, possible damages on the frequency converter will
mainly be limited to damages inside the unit.
For further information see Application Note Fuses and
Circuit Breakers.
