WARNING
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,
e.g. anti-condensation heating.
● 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.
WARNING
Line supply with non-grounded neutral point
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).

DANGER
Dangerous voltage
Electric machines contain hazardous voltages.
If the machine is not de-energized and brought into a no-voltage
condition, death or serious injury will occur.
When work is carried out on the machine with the terminal box open, it
must not be electrically connected!
