Safety Notices

.. After acceptance inspection and before being putting into service, the transformer
should be stored in dry and well-ventilated place.
.. Please adopt correct ways for lifting the equipment.
.. Before putting the equipment into service, please ensure that the elbow cable plug and
elbow lightning rod is reliably plugged into their sockets. Improper plugging-in will
pose great hazards to the equipment.
.. The elbow cable plug and elbow lightning rod must be reliably earthed.
.. For a transformer equipped with off-load tap changer, on-load tap switching is
absolutely forbidden.
.. Please use the insulated operation rod when carrying out such operations as earthing,
testing, isolating or switching on/off.
.. Operations to plug-in type fuse must be carried out in off-circuit state.
.. The load switch can only disconnect the rated current, but not the short-circuit current.
.. Long-time overload operation will affect the service life of the transformer.
.. Please follow all the instructions described in this manual when carrying out operations
related with product safety.
