8.3.2 CE Compliance

Fuses or Circuit Breakers are mandatory to comply with IEC 60364. Danfoss recommend using a selection of the following.
The fuses below are suitable for use on a circuit capable of delivering 100,000 Arms (symmetrical), 240V, or 480V, or 500V,
or 600V depending on the frequency converter voltage rating. With the proper fusing the frequency converter short circuit
current rating (SCCR) is 100,000 Arms.
