5.2.2. Removal of Knockouts for Extra Cables
1. Remove cable entry from the frequency converter (Avoiding foreign parts falling into the frequency converter when removing knockouts)
2. Cable entry has to be supported around the knockout you intend to remove.
3. The knockout can now be removed with a strong mandrel and a hammer.
4. Remove burrs from the hole.
5. Mount Cable entry on frequency converter.
5.2.3. Gland/Conduit Entry - IP21 (NEMA 1) and IP54 (NEMA12)
Cables are connected through the gland plate from the bottom. Remove the plate and plan where to place the entry for the glands or conduits. Prepare
holes in the marked area on the drawing.
The gland plate must be fitted to the frequency converter to ensure the specified protection degree, as well as ensuring proper cooling of the unit. If the
gland plate is not mounted, it may trip the unit.
