DANGER
Electric shock!
Danger of death due to electrical voltage when assembling/
disassembling the device.
► Switch off transformer on high-voltage side and low-voltage side.
► Lock transformer to prevent unintentional restart.
► Make sure 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.
WARNING
Electric shock!
Too small bending radii could damage the insulation of cables
or cores.
► Observe bending radii for the cables and their cores according to the
manufacturer's instructions.
WARNING
Fire hazard!
There is a fire hazard if the conductor material is not suitable
for the terminals. This can lead to severe burns and property
damage.
► Use copper conductors only.
CAUTION
Risk of burns!
Danger of bodily injuries due to heat!
► Winding temperature indicator: The potentiometer and the surfaces in
the vicinity can heat up considerably due to the CT current. Do not touch
this area.
