MedCenter DB3 manual General Arrangement, Operation

All cable glands should be of an equivalent NEMA/IP rating to that of the unit and integrated with the unit such that this rating is maintained.

Once termination is complete, carefully push the cover back onto the unit, avoid- ing damage to the mating surfaces. Tighten the 6 off cover screws evenly, to ensure maintenance of the required gap between the cover and enclosure.
