The serial number is found on the rating plate.
When DC link capacitors are formed, a defined voltage is connected to them and a defined
current flows so that the appropriate capacitor characteristics are re-established for them to
be re-used as DC link capacitors.
Components for the forming circuit (recommendation)
● 1 fuse switch 3-phase 400 V / 10 A
● 3 incandescent lamps 230 V / 100 W
● Various small components, such as lamp socket, cable 1.5 mm
Note
Line Modules must be enabled from the connected Motor Module.
