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.

Enclosure
The drive is intended to be mounted in an enclosure which prevents access except by
trained and authorized personnel, and which prevents the ingress of contamination. It is
designed for use in an environment classified as pollution degree 2 in accordance with
IEC 60664-1. This means that only dry, non-conducting contamination is acceptable.
