Heat dissipation
The heat generated by the SD750FR depends on the carrier frequency (Hz), the grid frequency and the
load. It can be estimated by the following equation, considering the worst case at rated power condition.

In order to avoid dust ingress in the LCL contactor, the drive integrates in its bottom part a special box
that contains it. The box’s grating is protected with a dust filter that may be cleaned or replaced
periodically depending on the ambient conditions. To clean or replace it, access from the rear part and
remove the screws that fix the grating.
