Modified SK 2x5E for compliance with Category 3D
For the operation of an SK 2x5E in ATEX Zone 22 only a modified frequency inverter is permissible. This
adaptation is only made at the NORD factory. In order to use the frequency inverter in ATEX Zone 22, the
standard cable glands are replaced with ATEX-approved brass cable glands, and the diagnostic
connections are replaced with connections made from aluminium / glass and other seals. The housing cover
is also coated with a UV-resistant paint.
