Information Derating
Due to its construction, the SK 2xxE has different derating characteristics according to the type of mounting
(motor-mounted / wall-mounted). Under certain circumstances this requires the selection of a higher power
frequency inverter than that which is nominally necessary. Therefore the technical data of the frequency inverter
(refer to manual BU0200) must be taken into account.
