Operation
Observe the following when carrying out any work on the machine:
● Comply with the general safety instructions (Page 1)
● Comply with the applicable national and sector-specific regulations.
● When using the machine within the European Union, comply with the specifications laid down in EN 50110-1 regarding
safe operation of electrical equipment.
Switching on the machine
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.
NOTICE
Risk of corrosion due to condensation
If the machine and/or ambient temperatures fluctuate, this can result in condensation inside the machine.
If available, remove the drain plugs or drain screws to drain the water depending on the ambient and operating
•
conditions.
If available, re-attach the drain plugs or drain screws.
•
If the motor is equipped with drain plugs, then the water can drain away by itself.
