Entellisys Low Voltage Switchgear
Chapter 4. Equipment Installation
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 a 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 Fig. 4–4 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
avail-able, 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.
