WARNING
Danger of injury due to improper fault
rectification
Improper fault rectification can lead to serious
personal injury and material damage.
For this reason:
– Before starting work, ensure there is adequate
space for the work.
– Make sure the work area is clean and orderly!
Components or tools that are loosely stacked or
left lying around are a source of accidents.
– If components were removed, make sure they
are remounted correctly, reinstall all fastening
elements and observe the specified screw-
tightening torques.
Electrical current
DANGER
Danger of death due to electrical current
Touching voltage-conducting parts poses an
immediate life-threatening hazard. Damage to the
insulation or to individual components can cause
fatal injury.
For this reason:
– For all work on the electrical systems, switch off
the voltage and test that the circuit is voltage-
free.
In addition to the device’s power supply, all
external voltages of signal and control lines
must also be free of voltage.
– Secure the power supply against being switched
back on again.
– Do not bypass or disable any fuses. When
exchanging fuses, check that they are of the
correct type.
– Keep moisture away from voltage-conducting
parts. This could otherwise result in a short-
circuit.
