Installation of VLT 5352-5552 380-500 V and VLT
5402-5602 525-690 V Compact Nema 1 (IP 21) and
IP 54
Cooling
All units in the above-mentioned series require a min-
imum space of 225 mm above the enclosure and must
be installed on a flat level surface. This applies to both
Nema 1 (IP 21) and IP 54 units.
Gaining access requires a minimum space of 579 mm
in front of the frequency converter.
Filter mats in IP 54 units have to be changed regularly
depending on the operating environment.
Side-by-side
Compact Nema 1 (IP 21) and IP 54
All Nema 1 (IP 21) and IP 54 units in the above-men-
tioned series can be installed side by side without any
space between them, since these units do not require
cooling on the sides.
NB!
IP54 units are not intended for direct out-
door installation. The IP54 rating does not
relate to other exposures as sun, icing,
wind blown driving rain. Under such cir-
cumstances Danfoss recommends to in-
stall the units in an enclosure designed for
these environmental conditions. Alterna-
tively, an installation at minimum 0.5 m
above surface and covered by a shed is
recommended.
