Breaker-To-Motor Starter Conversion
SECTION 3: RECEIVING, HANDLING, AND
STORAGE
Vacuum Starter Replacements are subjected to complete factory
production tests and inspection before being packed. They are
shipped in packages designed to provide maximum protection to the
equipment during shipment and storage and at same time to provide
convenient handling.
3.1 RECEIVING
Until the LV-VSR is ready to be delivered to the switchgear site for
installation, DO NOT remove it from the shipping crate. If the LV-VSR
is to be placed in storage, maximum protection can be obtained by
keeping it in its crate.
Upon receipt of the equipment, inspect the crates for any signs of
damage or rough handling. Open the crates carefully to avoid any
damage to the contents. Use a nail puller rather than a crow bar
when required.
When opening the crates, be careful that any loose items or
hardware are not discarded with the packing material. Check the
contents of each package against the packing list. Examine the
LV-VSR for any signs of shipping damage such as broken, missing
or loose hardware, damaged or deformed insulation and other
components. File claims immediately with the carrier if damage or
loss is detected and notify the nearest Eaton’s Electrical Services &
System office.
3.2 HANDLING
WARNING
DO NOT USE ANY LIFTING DEVICE AS A PLATFORM FOR PERFORMING
MAINTENANCE, REPAIR OR ADJUSTMENT. THE LV-VSR MAY SLIP
OR FALL CAUSING SEVERE PERSONAL INJURY. ALWAYS PERFORM
MAINTENANCE, REPAIR AND ADJUSTMENTS ON A WORKBENCH
CAPABLE OF SUPPORTING THE LV-VSR TYPE.
LV-VSR shipping containers are designed to be handled by a forklift
truck. If containers must be skidded for any distance, it is preferable
to use roller conveyors or individual pipe rollers.
Once a LV-VSR has been inspected for shipping damage, it is best to
return it to its original shipping crate until it is ready to be installed in
the Metal-Enclosed Switchgear.
When a LV-VSR is ready for installation, a lifting harness in
conjunction with an overhead lift or portable floor lift can be used
to move a LV-VSR. If the LV-VSR is to be lifted, position the lifting
device (lifting straps should have at least a 1600 pound capacity)
over the LV-VSR and insert the lifting harness hooks into the LV-VSR
side openings and secure. Be sure the hooks are firmly attached
before lifting the LV-VSR. Stand a safe distance away from the
LV-VSR while lifting and moving.
3.3 STORAGE
If the LV-VSR is to be placed in storage, maximum protection can be
obtained by keeping it in the original shipping crate. Before placing it
in storage, checks should be made to make sure that the LV-VSR is
free from shipping damage and is in satisfactory operating condition.
Outdoor storage is NOT recommended. If unavoidable, the outdoor
location must be well drained and a temporary shelter from sun,
rain, snow, corrosive fumes, dust, dirt, falling objects, excessive
moisture, etc. must be provided. Containers should be arranged
to permit free circulation of air on all sides and temporary heaters
should be used to minimize condensation. Moisture can cause
rusting of metal parts and deterioration of high voltage insulation.
A heat level of approximately 400 watts for each 100 cubic feet of
volume is recommended with the heaters distributed uniformly
throughout the structure near the floor.
Figure 3.1. Lifting (AK-2-25-LV-VSR Shown)
Indoor storage should be in a building with sufficient heat and
circulation to prevent condensation. If the building is not heated, the
same general rule for heat as for outdoor storage should be applied.
