4-2 Assembly and Installation of Switchgear
Equipment
General Requirements
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 Sections 4-1 and 4-2, and all embedded
conduits installed and capped.
NOTE: 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.
NOTE: Au cas où l’utilisation de rouleaux s’avérerait
nécessaire afin d’apporter l’équipement à son emplacement
permanent, nous recommandons que l’emballage
d’expédition ne soit pas enlevé tant que l’équipement n’est
pas positionné au dessus des boulons d’ancrage.
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.
NOTE: 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.
NOTE: Il faut avant de procéder à l’assemblage et à
l’installation s’assurer que la fondation soit absolument au
niveau et exempte de débris afin de prévenir des dommages
à l’équipement du dispositif de commutation.
Detailed Assembly and Installation
Instructions
The recommended procedure for installation of an indoor
switchgear or Load Center Unit Substation is as follows:
1. POSITION THE EQUIPMENT-Position the equipment or
sections of the complete equipment in their final location.
Fig. 4-4. Lifting plate location
NOTE: If the equipment line-up was split into shipping
sections, the lifting plates on corners of adjacent sections
shown in Fig. 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.
NOTE: Si l’ensemble de l’équipement a été séparé en sections
pour l’expédition, il faut que les plaques de soulèvement aux
coins des sections adjacentes montrées à la Figure 4–6
soient enlevées. L’omission d’enlever ces plaques viendra en
interférence avec les sections barres omnibus, de l’attache
de la structure des plaques, etc.
Once the lifting plates have been removed, they may be
discarded.
NOTE: 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.
NOTE: Dans l’éventualité où les plaques de levage doivent être
réassemblées sur l’équipement à des fins de levage, elles
doivent être déménagées aux endroits où il y a des trous de
boulons inutilisés, on y arrive habituellement en décalant la
plaque horizontalement sur la surface de montage d’un trou
de boulon de son emplacement précédent. Lors du
remontage des plaques de levage, serrer les boulons
d’assemblage à un couple de 7–9 livres-pied.
NOTE: All mating sections of the equipment line-up (including
transformer, if applicable) must be securely fastened together
prior to tightening anchor bolts fastening the equipment to
the mounting surface.
Fig. 4-5. View showing method of attaching equipment to
shipping skids
NOTE: Toutes les sections se rapportant à la disposition de
l’équipement (incluant le transformateur si tel est le cas)
doivent être retenues ensembles solidement avant de
resserrer les boulons d’ancrage qui retiennent l’équipement à
la surface de montage.
2. REMOVE THE SHIPPING SKIDS-The equipment is fastened to
the shipping skids with 3/8-3 lag screws through the
equipment anchoring holes. See Fig. 4-5.
