DANGER
Hazardous voltages
Electrical machines are at hazardous voltage levels. Contact with these can result in death,
serious injury or material damage.
Operating the machine on a line supply system with a non-grounded neutral point is only
permitted for short periods of time that occur rarely, e.g. the time leading to a fault being
eliminated. Cable ground fault EN / IEC 60034-1.
NOTICE
Damage to the machine or premature bearing failure
The bearings can be damaged if the following is not observed.
•
It is absolutely crucial that you maintain the permissible vibration values to avoid
damage to the machine or its destruction.
•
In operation, observe the vibration values in accordance with ISO 10816-3.
•
Under all circumstances maintain the minimum radial load of cylindrical roller bearings
of 50% corresponding to what is specified in the catalog.
•
Take the appropriate measures to reduce bearing currents. Observe the Chapter
Converter operation.
WARNING
Faults in operation
Changes with respect to normal operation indicate that there is an impaired function. This
can cause faults which can result in eventual or immediate death, severe injury or material
damage.
For instance, observe the following signs that could indicate a malfunction:
•
Higher power drawn than usual
•
Higher temperatures than usual
•
Unusual noises
•
Unusual smells
•
Response of monitoring equipment
Immediately contact the maintenance personnel if you identify any irregularities. If you are
in doubt, immediately switch off the machine, being sure to observe the system-specific
safety conditions.
