Safety instructions

WARNING

Danger of death or severe injury!

Danger of death or severe injury from explosive gases in the on-load tap-
changer / de-energized tap-changer, in the pipework system, at the dehy-
drating breather opening and from flying parts and hot oil splashing!
► If a protective device has been tripped or you suspect a fault, first check

the transformer, on-load tap-changer / de-energized tap-changer and mo-
tor-drive unit. Never operate the motor-drive unit electrically or with the
hand crank beforehand as long as the transformer is energized.

► Do not resume operation until the troubleshooting has been completed.
► Make sure that only trained technicians perform the work.
► Use suitable personal protective equipment/clothing.
► Ensure that there are no naked flames, hot surfaces or sparks (for exam-

ple caused by static charging) in the immediate surroundings and that
none occur.

► Ensure that all safety equipment for the on-load tap-changer / de-ener-

gized tap-changer is ready for use.

► Ensure that the oil compartment of the on-load tap-changer is correctly fil-

led with oil as per the instructions.
