Preparation
Follow all instructions related to the installation
of the switchgear to help avoid potentially
hazardous situations that could result in serious
injury or death.
If the switchgear will be installed near operational
equipment, it may be appropriate to erect
temporary barriers between that equipment and
the switchgear.
If you are adding sections to existing switchgear,
turn off all power supplying the equipment before
working on or inside it, and follow appropriate
lockout/tagout procedures.
Always use an appropriate voltage-sensing device
to confirm that the power is off prior to installing
or working with the switchgear.
Section installation sequence
Sections can be installed or added in any order,
and new sections may be added between existing
sections. If the sequential order designated during
manufacturing is altered on site by adding sections
to an existing lineup, the horizontal bus must be
reviewed as the length depends on the width of
the sections to be installed together. The main
bussing must match, and the related drawings
must be updated.
When adding, removing or rearranging sections, do
not exceed the maximum amperage available on
the horizontal bussing.
Install and connect shipping splits
Note: Diagrams showing the location of fasteners
and the appropriate torque values are included in
the Torque Table section of this manual.

Installation guidelines
Position shipping splits
Remove the shipping splits from their pallets or
skids. If you need to support a multiple-section
shipping split at the base after removing it from
the pallet, use supports at the corner of each
section. A two-section split must be supported at
8 points rather than 4.
Position the shipping splits in their final
arrangement and location. Connecting the sections
together before attaching them to the floor and/or
wall will help simplify splicing the horizontal bus.
If doors won’t close easily or panels are twisted or
stressed, this may indicate that the site is not
leveled. You may be able to shim the sections to
level them.
Connect sections
Note: Use only the provided fasteners to assemble
the switchgear.
Begin the installation at either the left or the right
end of the lineup by connecting the frames of the
sections together. The left side of each frame is
fitted with threaded inserts. Sections are fitted on
the right side with the necessary rivet nuts. Insert
the bolts from the left side of one frame to the
inserts in the adjoining section to the right.
