NOTE: If the equipment line-up was split into shipping sections,
the lifting plates on corners of adjacent sections shown in Fig.
4-6 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.

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. 4-7.
Equipment shipping sections up to 10 feet long will be fastened to
the skids with four lag screws, one in each corner. The shipping skid
and lag screws are expendable material and may be disposed of at
the purchaser's discretion.
3. FASTEN SECTIONS TOGETHER-After placement of the
equipment and installing the anchor bolts loosely, the various
shipping sections must be rigidly fastened together. Through-
bolts fasten each section of the switchgear equipment to the
adjacent section. Figure 4-8 shows the location of the
through-bolts.
