Invisible laser radiation
Looking directly into the beam or the reflected beam can cause eye damage.
The beam is emitted at the optical connections or at the end of the fiber-optic
cables connected to them on the assemblies. Read the chapter "Technical
Data" for further information.
▪ Never look directly into the beam or the reflected beam.
▪ Never look into the beam with the aid of optical instruments such as a
magnifying glass or a microscope.
▪ In the event that the laser beam strikes your eyes, close your eyes imme-
diately and move your head out of the path of the beam.
Working with current transformers
Dangerous high voltages may occur when a current transformer is operated
with an open secondary circuit. This can lead to injuries and property dam-
age.
▪ Never operate a current transformer with an open secondary circuit; short-
circuit the current transformer to prevent this.
▪ Observe the information in the current transformer operating instructions.
Handling electrical components
Electrical components can be damaged by electrostatic discharges.
▪ Never touch electrical components during commissioning, operation or
maintenance work.
▪ Take suitable measures (e.g. covers) to ensure that personnel cannot
touch components.
▪ Wear suitable personal protective equipment (e.g. grounded strap).
Hand crank aperture
Reaching into the hand crank aperture during a tap-change operation may
lead to injuries caused by a rotating drive shaft.
▪ Never reach into the hand crank aperture.
Securing the motor-drive unit
If you open the motor-drive unit during operation, there is a danger of electric
shock due to live components behind the swing frame.
▪ Secure the motor-drive unit against unauthorized opening during opera-
tion by using a padlock.
▪ The motor-drive unit may only be opened by an electrically skilled person.
Opening the swing frame
Opening the swing frame while the motor-drive unit is in operation may result
in electric shocks due to live components.
▪ The swing frame may only be opened by an electrically skilled person.
