Introduction
Type PSI pad-mounted switchgear is designed to make instal-
lation, operation and maintenance as simple as possible and to
provide dependable on-the-line service.
High quality materials and careful workmanship have been
combined to provide the best switchgear available. The switch-
gear has been thoroughly inspected and adjusted at the factory.
However, successful operation depends on proper installation
and care.
This manual has been written to assist you in obtaining long and
economical service from your switchgear.
Read this manual before installing and operating your switch-
gear.
Receiving
Upon receipt of the switchgear, check each item received for
shipping damage. Each item should be checked against the
shipping manifest to assure that the proper number of items
were received. Should any shortage or damage exist, a claim
must be filed at once with the carrier, and the Federal Pacific
agent or sales office must be notified.
Handling
The switchgear is securely mounted to a sturdy shipping pallet
with provisions for forklift use in removing the unit from truck.
The use of a forklift truck is not recommended, but if this method
is used the forks must extend through the skid to avoid damag-
ing the equipment.
Removable lifting plates are provided to allow the use of hooks
to lift the complete enclosure. The lifting device should be ar-
ranged to evenly distribute the lifting force between the lifting
plates. Do not lift at an angle less than 60 ° from the horizontal.
(See Figure 1)
Storage
The switchgear as received will be wrapped in a protective
plastic film. If the switchgear is not to be installed immediately,
the protective film must be removed for outdoor storage of unit.
Export or special packing is available as an option based on
customer's requirements and special conditions. Separate
instructions are available for these situations.
