Encapsulated Low Voltage Transformer
Three-phase encapsulated transformers are
manufactured to provide optimum performance for a lifetime
of uninterrupted service. Careful attention to the following
instructions is recommended for safe and reliable operation.
Installation, operation and maintenance of transformers
should be performed by authorized personnel, trained and
qualified in the installation, repair and maintenance of electrical
equipment.
As any other electrical equipment, transformers must
be installed according to the requirements of all applicable
national and local electrical codes. ANSI/IEEE C57-94 may
also be referred to for recommended installation, application,
operation and maintenance of three-phase encapsulated
transformers.
Transformers are palletized and can either be lifted via a
forklift truck or hoisted by the lifting lugs provided.
Appropriate lifting equipment should be used relative to
the size of each transformer. For safety purposes and to protect
the transformer, spreader bars are recommended.
No attempt should be made to lift or move a transformer
from any points on the unit other than those indicated. Refer
to page 17 (lifting brackets). Avoid subjecting transformer to
impact, jolting and other rough handling that may damage the
transformer.
Ensure the transformers are transported in upright
position - avoid tilting and tipping.
Immediately after receiving the transformer, it should be
inspected for any transit damage and for correctness against
the shipping documents.
The unit should be examined for any breaks in its
packaging, dented or damaged enclosures or missing parts
from the packing list.
If any damage is noted, a claim should be filed
immediately with the carrier and a second copy of all pertinent
information relative to the order and the circumstances
should be immediately communicated to the transformer
manufacturers local sales office.
