Section 2: Receiving, handling, and storing
2.1 Receiving
The equipment is shipped assembled in shipping sections/splits
without ducts and plenums installed. Depending on the length of
the lineup, it may be necessary to ship the equipment in several
shipping sections/splits to facilitate handling. Each shipping section/
split is shipped bolted to a wooden skid and covered with protective
material.
Only accept items from shipping carrier if all the items described on
the packing list have been received.
If the equipment has been damaged, file a claim as soon as possible
with the carrier and notify the nearest Eaton representative.
2.2 Handling
An Ampgard AR is equipped with insulated components for medium
voltage and must be protected against damage during handling.
The controller should always remain upright. Exercise extreme care
during any movement and placement operations to prevent dropping
or unintentional rolling or tipping. The preferred method of lifting and
maneuvering the shipping sections/splits into their final position is
with an overhead crane. Lifting plates are bolted to the top of each
shipping section. Attach a four-leg sling with hooks to all four lifting
plates to lift or move the sections. Do not allow the angle between
the lifting cables and vertical to exceed 45 degrees.
Each controller is properly adjusted at the factory before shipment.
However, vibration and mechanical stresses imposed by transit and
installation can adversely affect mechanical interlocks. Therefore, a
final inspection is essential before energizing.
Figure 11. Location of lifting plates.
After the section has been moved into installation position, remove
the hooks and lifting plates. Discard the lifting plates and hardware.

2.3 Storing equipment
Ampgard equipment contains insulating materials, electrical
contacts, and operating mechanisms which must be protected
against dirt, moisture, dust, foreign materials, corrosive atmo-
spheres, and extreme temperature changes. If it is necessary to
store the equipment before installation, place the equipment indoor
on a true and level surface in order to reduce strain and distortion in
the equipment. Cover and keep it in a clean and dry location with
ample air circulation and heat to prevent condensation.
NOTICE
STORING THE EQUIPMENT OUTDOORS IN NOT RECOMMENDED.
