DANGER
Electric shock!
An energized transformer could cause death or serious injuries.
► Switch off transformer on high and low-voltage side.
► Lock transformer to prevent unintentional restart.
► Ensure that everything is de-energized.
► Visibly connect all transformer terminals to ground (grounding leads,
grounding disconnectors) and short circuit them.
► Cover or cordon off adjacent energized parts.
DANGER
Electric shock!
Working on the on-load tap-changer when on-load tap-changer components
are energized can lead to death or serious injuries.
► De-energize all auxiliary circuits, such as the tap-change supervisory de-
vice, pressure relief device, pressure monitoring device.
► Make sure that everything is de-energized.
WARNING
Danger of explosion!
Explosive gases in the oil compartment of the on-load tap-changer, trans-
former, pipe system, oil conservator and at the dehydrating breather open-
ing can deflagrate or explode and result in severe injury or death.
► Ensure that there are no ignition sources such as naked flames, hot sur-
faces or sparks (e.g. caused by the build-up of static charge) in the trans-
former's immediate surroundings and that none occur.
► Do not operate any electrical devices (e.g. risk of sparks from impact
wrench).
► Only use conductive and grounded hoses, pipes, and pump equipment
that are approved for flammable liquids.
NOTICE
Damage to motor-drive unit!
Damage to the motor-drive unit due to condensate in protective housing of
motor-drive unit.
► Always keep protective housing of the motor-drive unit tightly closed.
► In the event of operation interruptions of more than 2 weeks, connect and
operate the anti-condensation heater in the motor-drive unit. If this is not
possible, e.g. during transportation, place a sufficient amount of desiccant
in the protective housing.
