DANGER
Hazardous voltages
Death, injury or material damage can occur. Note the following
safety information before connecting-up the machine:
• Only qualified and trained personnel should carry out work on
the machine while it is stationary.
• Disconnect the machine from the power supply and take
measures to prevent it being reconnected. This also applies to
auxiliary circuits.
• Check that the machine really is in a no-voltage condition.
• Establish a safe protective conductor connection before
starting any work.
• If the incoming power supply system displays any deviations
from the rated values in terms of voltage, frequency,
curve form or symmetry, such deviations will increase the
temperature and influence electromagnetic compatibility.
• Operating the machine on a line supply system with a non-
grounded neutral point is only permitted over short time
intervals that occur rarely, e.g. the time leading to a fault being
eliminated (ground fault of a cable, EN 60034-1).
