Procedure
1. Switch off all power supplies (line supply and external 24 V power supply) to the converter.
2. Remove the connecting cables of the converter.
3. Remove the defective converter and install the new converter.
4. Adjust the electromechanical potentiometers to make sure the scaling is set as same as the
replaced converter.
5. Connect all of the cables to the converter.
6. Switch on all power supplies (line supply and external 24 V power supply) to the converter.
Set the new converter to suit the application:
– If the settings of the replaced converter are backed up on an external storage medium,
– If there is no data backup of the replaced converter, recommission the converter.
7. For converters with safety functions enabled, perform a reduced acceptance test.

WARNING
Electric shock as a result of a residual charge in power components
After the power supply has been switched off, it takes up to 5 min. until the capacitors in
the converter have discharged so that the residual charge is at a non-hazardous level.
• Check the voltage at the converter connections, before removing the connection
cables.

NOTICE
Damage caused by interchanging the motor cables
The direction in which the motor rotates switches if you exchange the two phases of the
motor line. An incorrect direction of rotation can lead to damage in the machine or
system.
• Connect the three phases of the motor lines in the right order.
transfer the settings to the new converter.
