Bypass Unit Enclosures
All Bypass units are intended for non-hazardous locations. Various enclosure types are provided to protect against the applica-
tion environmental conditions:
„
Nema Type 1 Enclosures
These are constructed for indoor use to provide a degree of protection against incidental contact with enclosed electrical equip-
ment and falling dust or dirt.
„
NEMA Type 12 FVFF Enclosures
NEMA provides for both non-ventilated and ventilated NEMA 12 enclosures. When ventilated, a suffix to the type number
defines the ventilation method. A NEMA 12 FVFF enclosure has Forced Ventilation with inlet air Filter and outlet air Filter.
The internal pressure is positive with respect to the ambient pressure. UL does not recognize NEMA 12 ventilated enclosures,
therefore, these enclosures are designated NEMA 1 for UL purposes.

Note 1: Horsepower rating is based on a standard NEMA B 4-pole motor.
Note 2: The underscore position in these model numbers codes for the enclosure type: V = NEMA1, B = NEMA12 FVFF.
Note 3: Heat loss is the amount of heat dissipated by the drive at full load with all standard options available inside the enclosure. Drive heat sink losses are
included in the heat loss data.
Note 4: Height dimension (H) excludes the mounting screw tabs. Depth dimension (D) excludes the disconnect handle.
Note 5: This data represents the total weight with all possible standard options. Weight could be less depending on the options specified.
Note 6: All standard options are available in this size enclosure.
