3.3.6. 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 frequen-
cy 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.
Illustration 3.25: Cable entry viewed from the bot-
tom of the frequency converter - Enclosure D1 and
D2.
Illustration 3.26: Cable entry seen from the bot-
tom of the frequency converter - Enclosure E1.
The bottom plate of the E1 enclosure can be mounted from either in- or outside of the enclosure,
allowing flexibility in the installation process, i.e. if mounted from the bottom the glands and cables
can be mounted before the frequency converter is placed on the pedestal.
