Frame and Enclosure
P
General
-
7.1.1
A power unit shall be formed and assembled so that it has the
strength and rigidity necessary to resist the abuses to which it
is subjected, without increasing the risk of fire, electric shock, or
injury to persons due to total or partial collapse which results in
a reduction of spacings, loosening or displacement of parts, or
other serious defects.
P
7.1.2
A power unit shall be provided with an enclosure to house all
parts other than the power supply cord or primary connector
and the output leads or output connector that present a risk of
fire, electric shock, or injury to persons under any condition of
use.
P
7.1.3
A cast- or sheet-metal section of the enclosure shall have a
thickness not less than that specified in Table 7.1.
Metal enclosure
P
Exception: A part of an enclosure that complies with the
Mechanical Strength Tests for Metal Enclosures, Section 45,
need not comply with the thickness specified in Table 7.1.
P
7.1.4.
An enclosure or part of an enclosure that also serves as a
compartment for a rechargeable vented battery shall be
ventilated to permit dispersion of gases from the battery.
N/A
7.1.5
In addition to the criteria specified in this Standard, the
following factors are to be considered when judging the
suitability of a polymeric enclosure:
Metal enclosure
P
a) Moisture absorptive properties;
P
b) Material flammability properties; and
P
c) Resistance to arcing properties.
P
These properties shall comply with the requirements in the
Standard for Polymeric Materials - Use in Electrical Equipment
Evaluations, UL 746C. See also 39.4.

7.1.6
A conductive coating applied to a nonmetallic surface such as
the inside surface of a cover, enclosure, and the like shall
comply with the appropriate requirements in the Standard for
Polymeric Materials - Use in Electrical Equipment
Evaluations, UL 746C, unless it can be determined that flaking
or peeling of the coating does not result in a reduction of
spacings or the bridging of live parts that may result in a risk of
fire, electric shock, or injury to persons.
No such coating
N/A
7.1.7
The enclosure of a power unit shall prevent molten metal,
burning insulation, flaming particles, or the like from falling on
combustible materials, including the surface upon which the
power unit is supported. A barrier as mentioned in 7.1.10 shall:
P
a) Be horizontal;
No barrier
N/A
b) Comply with Figure 7.1; and
N/A
c) Comply with 7.1.8 if it is made of a polymeric material.
N/A
Openings for drainage, ventilation, and the like may be
employed in the barrier provided such openings do not permit
molten metal, burning insulation, or the like, to fall on
combustible material.
No opening
N/A
7.1.8
With reference to 7.1.7, a barrier made of a polymeric material
shall:
No such barrier
