Mount Your Drive Where You Want to, Not Where You Have to
December 15, 2020
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 classifica- tion, 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.

NEMA 250 Standard
Type 3R
Enclosures constructed for either indoor or outdoor use. Protection against rain, sleet, snow. Will be undamaged by external formation of ice on the enclosure. Due to a drain hole, the class is comparable to IP 23.
NEW!
One of the smallest NEMA 3R solutions for drives from 55-400 kW is now available.
To achieve the NEMA 3R rating, the drive must be ordered with an “E5S” enclosure, which includes an anti- condesation heater and stainless steel screws on the outside of the drive. The corresponding kits must be ordered to complete the protection. The kit consists of the cover (with rain hood and air baffle), special gland plate, and cover vent plate.
Type 4X
Enclosures constructed for either indoor or outdoor use. Protection against windblown rain, sleet, snow, splashing water and hose directed water. Will be undamaged by external formation of ice on the enclosure.
Type 4X is also used inside, where equipment is washed with soap/ solvents. Reliability tested under specific weather conditions, including water spraying until ice forms on the exterior and prolonged exposure to salt spray. This class is comparable to IP 66.
Outdoor weather shield
Designed to be mounted above the VLT® drive to protect from direct sun, snow and falling debris.

Stainless steel back plate
Used to direct air from the fan through the rear heat sink. This is required when drive is not mounted against a flat surface, panel, or wall.
Watertight USB plug
A USB plug can be mounted in the base of the enclosure, allowing the drive to stay closed while making setup or programming changes using MCT 10 setup software.
