3.2 Fire protection
The drive enclosure is not classified as a fire enclosure. A separate fire enclosure must
be provided.
For installation in the USA, a NEMA 12 enclosure is suitable.
For installation outside the USA, the following (based on IEC 62109-1, standard for PV
inverters) is recommended.
Enclosure can be metal and/or polymeric, polymer must meet requirements which can
be summarized for larger enclosures as using materials meeting at least UL 94 class
5VB at the point of minimum thickness.
Air filter assemblies to be at least class V-2.
The location and size of the bottom shall cover the area shown in Figure 3-1. Any part of
the side which is within the area traced out by the 5° angle is also considered to be part
of the bottom of the fire enclosure.
Figure 3-1 Fire enclosure bottom layout
The bottom, including the part of the side considered to be part of the bottom, must be
designed to prevent escape of burning material - either by having no openings or by
having a baffle construction. This means that openings for cables etc. must be sealed
with materials meeting the 5VB requirement, or else have a baffle above.
See Figure 3-2 for acceptable baffle construction. This does not apply for mounting in
an enclosed electrical operating area (restricted access) with concrete floor.
