(1) Do not lift or move a transformer without proper equipment and experienced personnel. On
some larger kVA distribution transformers, lifting provisions are provided on the inside of the
enclosure on the core & coil.
(2) Do not off-load the transformer until a full inspection has been completed.
(3) Use terminals only for electrical connections. Flexible connectors are recommended for bus
connections. The transformer terminals are not designed to support the weight of supply or load
cables. Uni-strut supports can be added in the field providing proper clearances are maintained.
(4) Connections should only be in accordance with the nameplate diagram or connection drawings.
(5) Make sure all power is disconnected before attempting any work on a transformer or inside of
control box and ground all windings.
(6) Make certain all ground connections, line terminals and selected taps are complete and tighened
before energizing the transformer.
(7) Do not attempt to change any taps - primary or secondary, while the transformer is energized.
(8) Do not change connections when the transformer is energized.
(9) Do not tamper with control panels, alarms, interlocks or control circuits.
(10) Do not adjust or remove any accessories or cover plates while the transformer is energized.
No supply cables should come in contact with the core or any live part except the terminal that it
is intende for.
