Section 3—Receiving, Handling, and Storing Power-Style™ QED-2 Switchboards

ENGLISH
When elevating a shipping section not equipped with lifting straps, use an
overhead crane equipped with either of the following:
• A chain coupled to a sling rigging
• A wire cable with safety hooks and shackles
Wrap the sling completely around the switchboard and shipping stringers.
NOTE: A forklift is an alternative method of handling the switchboard. Always
check the fork lengths to ensure that the forks extend under the entire
switchboard. Carefully balance the load, and always use a safety strap when
handling or moving a switchboard with a forklift (Figure 4 on page 12).
Storing
When storing the switchboard before installation, cover the top and openings
of the equipment during the construction period to protect the switchboard from
dust and debris.
If a switchboard is not installed and energized immediately, store it in a clean, dry
space with a consistent temperature to prevent condensation. Store the
switchboard indoors, if possible. Preferably, store it in a heated building with
adequate air circulation and protect it from dirt, fumes, water, and physical
damage. Storing the switchboard outdoors can cause harmful condensation inside
the switchboard.
NOTE: Install portable electric heaters of approximately 250 watts per vertical
section in both indoor-type and rainproof-type switchboard enclosures for
adequate protection during storage.
Before energizing the space heaters, remove all loose packing or flammable
materials inside the switchboard. Outdoor switchboards are not weather-resistant
until completely and properly installed; treat them the same as indoor switchboards
until after installation.
WARNING
TOP HEAVY LOAD—HAZARD OF TIPPING
• Stabilize the shipping section to reduce the possibility of tipping.
• Consult with a certified rigging and lifting expert for any situation not covered
in these instructions.
Failure to follow these instructions can result in death or serious injury.
