m
WARNING
DO NOT USE ANY LIFTING DEVICE AS A PLATFORM FOR PERFORMING
MAINTENANCE, REPAIR OR ADJUSTMENT. THE GROUND AND TEST
DEVICE MAY SLIP OR FALL CAUSING SEVERE PERSONAL INJURY.
ALWAYS PERFORM MAINTENANCE, REPAIR AND ADJUSTMENTS ON A
WORKBENCH CAPABLE OF SUPPORTING THE GROUND AND TEST DEVICE
TYPE.
DHP ground and test device 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 G&T device 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-Clad Switchgear.
When a ground and test device is ready for installation, a lifting
harness in conjunction with an overhead lift or portable floor lift can
be used to move a G&T device. This could be preferable to rolling
the G&T device on the floor using self-contained wheels. If the G&T
device is to be lifted, position the lifting device (lifting straps should
have at least a 1600 lb capacity) over the G&T. Stand a safe distance
away from the device while lifting and moving.

3.3 STORAGE
If the ground and test device 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 G&T device 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. Container 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.
Indoor storage should be in a building with sufficient heat and air
circulation to prevent condensation. If the building is not heated, the
same general rule for heat as for outdoor storage should be applied.
