various accessories.
8. Energizing the switchgear, outlines the steps
to be taken before and during the electrical
energization of the equipment.
9. Maintaining the switchgear, provides
instructions for all preventive maintenance,
servicing, and lubrication information for the
switchgear equipment. Included is service and
maintenance data for the circuit breakers,
instrument compartments, instruments, bus
bar joints, and cable and busway connections.
This section also includes paint refinishing
requirements.
Appendices A, B, and C, contain information
concerning screw and bolt torque values,
circuit breaker rejection features, and circuit
breaker information.

view and floor plan.
2. Elementary and connection drawings (or wiring
routing tables) which indicate and identify test
and connection points including terminal blocks,
device studs, switch contact developments, and
remote connections.
3. Summary of switchgear equipment which is a list
of all the components furnished with the
switchgear, including the breakers, identified by
catalog number.
These are all the documents necessary to install,
operate, and maintain the equipment. One
complete set of drawings and instruction
books is shipped with the equipment.

2. RECEIVING, HANDLING AND STORAGE
2.1 Receiving
Equipment packages
Every package leaving the factory is plainly marked
with the case number, requisition number, and
customer's order number. If the equipment has
been split for shipment, the section numbers of
the equipment enclosed in each shipping package
are identified.
Note: To avoid the loss of any parts when
unpacking, the contents of each container should
be carefully checked against the packing list before
discarding the packing material.
Remarque: Pour éviter toute perte de pièces au
cours du déballage, vous devez soigneusement
comparer le contenu de chaque boîte au bordereau
d'expédition avant de jeter le matériel d'emballage.
The contents of each shipping package are listed
on the Master Packing List. In addition, this list
includes the number of the shipping crate in which
miscellaneous parts needed to install and operate
the equipment (such as hardware, contact
lubricant, touch-up paint, breaker closing devices,
etc.) are located. Normally, such devices are packed
in a cardboard carton and the carton secured in an
empty switchgear compartment. See Fig. 2.1. If
such items are packed in a switchgear section
instead of a separate crate, the list will indicate
the appropriate section number in which they are
stored. Large items (such as breaker lifting devices
and dollies used with indoor equipment) will always
be shipped in separate crates or cartons.
See Fig. 2.2.
Inspecting for damage
All equipment leaving the factory is carefully
inspected and packed by personnel experienced
in the proper handling and packing of electrical
equipment. Upon receipt of any equipment,
immediately perform a visual inspection to
ascertain if any damage has been sustained in
shipping or if there are any loose parts. Circuit
breakers may be shipped separately in individual
containers with the breaker in the open position.
Circuit breakers should be unpacked and visually
inspected for damage or loose parts as soon as
possible after they have been received.
Be sure to inspect all devices mounted or packed
inside compartments of each section to see if any
have been dislodged or damaged.
Filing a claim
If any damage is evident, or indication of rough
handling is visible, file a claim for damage at once
with the transportation company and notify your
ABB sales representative immediately. Information
on damaged parts, part number, case number,
requisition number, etc., should accompany
the claim.

2. RECEIVING, HANDLING AND STORAGE
2.2 Handling
Note: It is preferable to leave the shipping skids in
place under the switchgear until it reaches its final
location. The equipment should be installed in its
final location prior to installing the circuit breakers.
Remarque: Il est préférable de conserver les
cales d'expédition à leur place sous l'appareillage
électrique jusqu'à ce que celui-ci ait atteint sa
destination finale. Installez l'équipement dans
son emplacement final avant d'installer
les disjoncteurs.
Indoor enclosure lifting
The indoor switchgear sections are best handled by
lifting with a crane as shown in Fig. 2.3. Removable
lifting plates are provided, as standard equipment,
on the top of each switchgear section. To preserve
the external appearance of the equipment, it is
suggested that the lifting plates be left in place
except where adjacent equipment must be bolted
together, i.e. shipping splits, etc.
Utilize four equal length cables and an overhead
crane, each with a minimum load rating of twice the
weight of the switchgear. Estimated weights for
shipping splits appear on the Front View drawings.
Example: Switchgear section weight = 5,000
pounds. The crane and the four lift cables must
have a minimum load lifting capacity of
10,000 pounds.
Note: The angle between the cables and the
top of the equipment must be at least 45
degrees. If this is not possible because of
lack of headspace, spreader bars must be
used. Also, lift cables with greater load
capability may be necessary, depending
upon the angle between the cables and
the crane hook.
Remarque: L'angle entre les câbles et le haut
de l'équipement doit être d'au moins 45
degrés. Si l'espace est insuffisant pour cela,
vous devez utiliser des barres d'écartement.
Il est également possible que vous ayez à
utiliser des câbles de levage présentant une
capacité de charge supérieure, en fonction
de l'angle existant entre les câbles et le
crochet de la grue.
Connect a cable from the crane to the four lifting
plates located on the top-front and rear of the
switchgear (Fig. 2.3).
