WHICH FOLLOW EMPHASIZE THE UNIQUE FEATURES ASSOCIATED WITH
MAGNUM DS LOW-VOLTAGE NEMA 3R ASSEMBLIES.
2.1 General Information
Magnum DS Metal-Enclosed Low-Voltage assemblies are shipped
in one or more shipping groups, depending on the number of verti-
cal sections, or the limitations of handling facilities at the installa-
tion site. This could typically result in three or four sections for a
complete assembly. Maximum length of a preassembled NEMA 3R
shipping section is 108” (2743 mm) including a transformer connec-
tion throat, if applicable.
All shipping sections are shipped so as to be protected from the
weather during shipment but are not suitable for storage outdoors
as shipped. NEMA 3R assemblies are not weatherproof until com-
pletely assembled. Treat them the same as indoor equipment until
fully assembled.
2.2 Receiving
When a Magnum DS Low-Voltage assembly reaches its destination,
the purchaser should check the material received against the ship-
ping list to be certain that all items have arrived. Note accurately any
discrepancies. Each shipping group is plainly marked with or accom-
panied by an identifying shop order number, general order number
and shipping weight. Each shipment includes a contents list which
is a part of the overall package of shipping papers. To avoid the loss
of any parts, the contents of each container should be carefully
checked against the packing list. Do not discard any packing mate-
rial until it is certain that every item has been received in the proper
condition and that certain packing material will not be required later
for equipment storage. Larger items, such as portable traveling lift-
ers, are shipped in separate cartons. Other loose and unmounted
items may be packed in additional cartons. These items, such as
shipping split hardware, should be logged in and set aside in a safe
location until the assembly has been set in its final position.
Equipment shipped from the factory is carefully packed and inspect-
ed prior to its departure. On occasion, however, equipment damage
is incurred during transportation. If any damage is found, file a dam-
age claim immediately with the transportation carrier and notify an
Eaton representative. All claims should be filed as soon as possible
and include applicable part numbers, shop order numbers and/or
general order numbers
2.3 Precautions
It is preferable to use an overhead crane when moving the assem-
bly. Circumstances at the installation location may prevent the use of
an overhead crane for all movement. In such instances, the careful
use of rollers can be employed. Although the methods for moving
NEMA 1 and NEMA 3R assemblies are similar, the techniques vary
slightly. The differences are highlighted in this section.
2.3.1 Overhead Lifting
WARNING
FAILURE TO FOLLOW LIFTING INSTRUCTIONS MAY RESULT IN DEATH
OR SERIOUS BODILY INJURY. READ INSTRUCTIONS FOR LIFTING
SWITCHGEAR PRIOR TO ATTACHING CABLES, CHAINS OR SPREADER
BARS.
Lifting plates are attached along the assembly base at the front and
rear for crane cable attachment. Suitably sized spreader bars (not
provided) must be placed between lift cables to prevent equipment
damage (Figure 1). If it appears that the cables will touch the assem-
bly during the lifting process, place appropriately sized lumber along
the sides where contact could be made between the cable and the
equipment. This will prevent damage caused by the lifting cables.
