Danfoss FC series can withstand even the harshest pressure washing environments.
A NEMA/UL Type 4X rated enclosure provides maximum mounting flexibility

Outdoor installation

Many VLT® drives are installed outdoors
therefore 4x ratings are available for
FC series up to 90 kW and NEMA 3R
up to 250 kW. NEMA is a technical
standard from the National Electrical
Manufacturers Association (NEMA).

This standard, unlike the IP classifica­tion, includes reliability testing under
specific weather conditions for certain
classes. For example, the unit is
exposed to a water spray until ice forms
on the exterior. Prolonged exposure to
salt spray is also tested.

Improved reliability

As with the IP ratings, the user can
Use specific NEMA ratings to decide
the suitability of the unit for certain
environmental conditions – although
the unit‘s base specification always
remain valid, Danfoss offers a protective
weather shield to prevent air vents
becoming blocked by leaves or other
debris. The LCP is also protected against
UV – as is the whole enclosure.

3rd party testing

The FC-Series has received certification
from an independent body,
Underwriters Laboratories (UL) and
has achieved Type 4X approval up to
90 kW and NEMA 3R up to 250 kW. For
details, including Type 3R, refer to drive
documentation.
