6.5 Forming the DC link capacitors
● 6 incandescent lamps 230 V / 100 W for a line voltage of 500 to 690 V 3 AC, where 2
● Various small components, such as lamp sockets, cable 1.5 mm
Forming circuit for Line Modules
Note
Forming the Line Modules
Voltage must be supplied to Line Modules via a connected Motor Module and the associated
DC link.

incandescent lamps must be connected in series in each supply phase.
Alternatively, use 3 resistors of 1 kΩ / 160 W each (e.g. GWK200J1001KLX000 from
Vishay) instead of the incandescent lamps.
CAUTION
Install lamp sockets so that they are insulated
For a line voltage of 500 to 690 V 3 AC, the two lamp sockets connected in series must
be insulated and protected from touch, because the insulation of the sockets is not
designed for this high voltage.
