Polymeric Enclosures
Polymeric enclosures shall comply with the requirements of
(a)flame test specified in Clause 6.11 unless the polymeric
compounds used in the construction of the enclosure are
classified as 5-V•A material in accordance with CSA Standard
C22.2 No. 0.17; and
(b)impact test specified in Clause 6.12.1.

No openings in Enclosures
N/A
4.2.5.1
The enclosure shall have no openings through which the
articulated probe (see Figure 1) can be inserted so as to touch
moving parts (e.g. fan blades), or any uninsulated live parts
(including film-coated wire) operating at a voltage of more than
42.4 V peak to any other part or to ground (see Clause 4.2.6.1).
N/A
4.2.5.2
The probe of Figure 1 shall be inserted to any depth that the
opening will permit, using an applied force of not greater than
4.4 N. The probe shall be rotated or angles before, during, and
after insertion through the opening to any necessary position,
using any possible configuration. If necessary, the
configuration shall be changed after insertion through the
opening.
N/A
4.2.5.3
Openings in the top of an enclosure that are directly over
uninsulated live parts involving a risk of shock or energy hazard
shall not exceed 5 mm in any dimension unless the
construction is such that straight access to those uninsulated
live parts is prevented. See Figure 2 for examples of top cover
designs that prevent straight access. This requirement shall
not apply to a UPS over 1.8 m high.
N/A
4.2.5.4
Openings in the vertical sides of an enclosure for cord-
connected power supplies rated 120 V, 1500 W and less shall
(a) not exceed 5 mm in any dimension;
(b) not exceed 1 mm in width regardless of length;
(c) be provided with louvers that are shaped to deflect outwards
an external vertically falling object (see Figure 3 for examples);
or
(d) be so located that an object, upon entering the enclosure, is
unlikely to fall on uninsulated live parts, resulting in a shock or
energy hazard (see Figure 4).
N/A
4.2.5.5
A PCE having an enclosure with openings that are located
directly beneath live parts shall be
(a) provided with a barrier or bottom panel complying with
Clause 4.2.5.7, located beneath such live parts so as to prevent
molten or flaming particles from falling on the surface on or
over which the PCE is mounted; or
(b) marked as specified in Clause 5.11, if intended for floor
mounting.
