Modifications
If this enclosure has been provided with customer-specified modifications, any
openings must be filled with UL Listed components or fittings with environmental
ratings equal to the enclosure's environmental rating to preserve the desired
rating. Any modification must be made to the components manufacturer's
specifications.
Type 2, 3R, &/or 3RX enclosures require a drainage opening in the enclosure.
Drainage openings shall not be less than 3.2
mm
(1
/8") in diameter or more than
6.4
mm
(1/4") in diameter. The hole
must
be located in the lowest part
of

Installation
of
Conduits and Grounding
Conduit holes can be made in the enclosure in any location
per
applicable codes
and standards. Rigid, metallic and non-metallic conduit and fittings can be used,
as well
as
appropriate liquid-tight flexible conduit systems Ho
le
saws, speed
bores,
or
hydraulic punches can be used.
In
order to maintain required
environmental ratings, only the use
of
UL
Listed metallic conduit hubs with
environmental ratings appropriate for the end use are required.
Metallic conduits must be grounded. Bonding between conduit connection is not
automatic and must be provided as a part
of
the installation.
In order to prevent enclosure damage and to maintain enclosure requirements,
conduits should
be
aligned to prevent unnecessary stress on enclosure walls.
