AKD-20 AR / Entellisys AR Low-voltage Switchgear
Section 4. Equipment Installation
Assembly and Installation of Switchgear
General
Before assembling or installing the switchgear equipment, all
components should be available at the site location. This will
facilitate switchgear component identification as well as
installation. The foundation should be prepared in
accordance with the instructions in Foundation Requirements
and Foundation Preparation and all embedded conduits
installed and capped.
If a transformer is not part of the installation, and/or the
equipment has been split for shipment, place the center
section on the foundation first. Assemble the remaining
sections outward from the center section, in each direction.
If the switchgear equipment is part of a Load Center Unit
Substation, the transformer section should be set on its pad
first in accordance with the instructions furnished with the
transformer. All remaining sections of the switchgear should
then be installed.
NOTICE: If rollers are to be used for movement of the
equipment to its permanent installation, it is recommended
that the shipping skid not be removed until the equipment
is placed in position over the anchor bolts.
NOTICE: Before assembling and installing the switchgear
equipment, the foundation must be absolutely level and
clear of debris to prevent damage and possible
misoperation of the switchgear equipment.
Detailed Assembly and Installation Instructions
Indoor Equipment
The recommended procedure for installation of an indoor
switchgear or Load Center Unit Substation is as follows:
Position the Equipment
Position the equipment or sections of the complete
equipment in their final location.
Remove any lifting plates (Figure 4.4) on the sides of adjacent
joining equipment sections.
Once the lifting plates have been removed, they may be
discarded.
NOTICE: If the equipment lineup was split into shipping
sections, the lifting plates on corners of adjacent sections
(Figure 4.4) must be removed. Failure to remove these
plates will interfere with mating adjacent sections and
prevent installation of bus splice plates, structure tie plates,
etc.

NOTICE: In the event the lifting plates must be reassembled
on the equipment for lifting purposes, they must be moved
to locations where unused screw holes are available.
Generally achieved by shifting the plate horizontally on the
mounting surface one bolt hole from its previous location.
When remounting the lifting plates, torque the mounting
bolts to 7-9 ft.-lbs.
NOTICE: All mating sections of the equipment lineup
(including transformer, if applicable) must be securely
fastened together prior to tightening the anchor bolts
fastening the equipment to the mounting surface.
