Oberon Model 1021-00 enclosure with screw on cover
Cable Egress and NEMA 4
The Models 1020 and 1021 are easily drill for cable pass through and installing
accessories. The most important step during installation is to ensure connectors
are properly sealed to maintain the NEMA 4 rating. Water tight conduit such as
Anamet Sealtite® coupled with a cable gland or other sealing connector may be
used to prevent fluid from entering the enclosure.
A pressure equalizing vent such as a GORE® Vent may be help reduce
condensation. The GORE® Vent allows air pressure equalization between inside
and outside the enclosure, yet restricts the passage of water vapor from outside
to inside. This can help to reduce condensation.
Model 3010 Installation on Uneven Surfaces
Oberon’s Model 3010 incorporates a sturdy Aluminum back panel that fastens
down to a surface. As with the Models 1020 and 1021, choose a surface that is
smooth and level for installation. Four cushioning washers are provided with
each product to lift the back panel about 1/8" above the potentially uneven or
irregular surface. Fastening the back panel without the cushioning washers on an
uneven surface may cause bending and flexing. If the panel is bent, the cover
holes will no longer align properly to the panel hardware, and the gasket will not
seal flat along the plane surface. When fastening to a surface, use wall anchors
suited for the wall material or construction, and tighten to the same torque on all
sides.
