To avoid personal injury or damage to the panelboard assembly, always
securely fasten the cast aluminum breaker housing before securing the
terminal housing.
To avoid the risk of explosion, always clean both flat joint surfaces of body
and cover before closing. Dirt or foreign material must not accumulate on
flat joint surfaces. Surfaces must seat fully against each other to provide a
proper explosionproof joint.
If your product was supplied with a sheet metal terminal housing, be sure to
read the D2L installation with sheet metal terminal enclosure (D2LBS/
D2LCS/D2LDS) instructions completely before beginning installation. If your
product was specified with alternate feed or no terminal housing, be sure
to read the alternate feed (suffix A) or no terminal enclosure (EPLBN/
EPLCN/EPLDN) installation instructions completely before beginning
installation.
To avoid the risk of explosion, do not add or enlarge conduit entries in cast
enclosures.
GENERAL INSTALLATION, MOUNTING &
LIFTING
1.
Select a mounting location that will provide suitable strength and rigidity for
supporting the panel board and all components.
Refer to Figure 1 for mounting dimensions and approximate weights. Note:
Refer to Field Installable Kits - Section E if you are using an EPLA MTG KIT
or D2LS MTG KIT installation.
2.
Install detachable mounting feet while enclosure is on the floor or work
bench.
•
Insert wedge shaped mounting feet into dovetail on all cast enclosures.

3.
Use dedicated lifting eye to mount enclosure on suitable mounting surface.
Refer to Lifting Diagrams (Figure 2) for appropriate lifting procedure.
4.
Align enclosure with the two left side mounting feet on selected mounting
surface. While continuing to support the enclosure in position, install the
right two bolts of breaker enclosure. Securely tighten all bolts around
breaker enclosure. If a terminal housing has been supplied, securely fasten
four remaining bolts for that enclosure after breaker housing is fastened.
Note: There is a distance between terminal and breaker enclosure
mounting surfaces. Do not bend or distort union assemblies. Provide
adequate mounting or use available mounting kit.
To avoid the risk of explosion, all unused conduit openings must be closed
properly with an approved plug, drain or breather such as Crouse-Hinds
series PLG plugs or ECD breather/drains.
Division 1 panels with conduit runs 2" and higher require sealing fittings
installed within 18" of enclosure.
5.
With panelboard securely fastened to the mounting surface, remove plastic
plugs from desired entries.
6.
After enclosure is positioned and secured in its permanent location, pull
wires into panelboard terminal enclosure, making sure that they are long
enough to make the required connections.
7.
Make sure all screws and bolts are tightened to the appropriate torque
values found in Chart 1 below.
