11.5 Forming the DC link capacitors
● Six incandescent lamps 230 V / 100 W for a line voltage of 3 AC 500 to 690 V, where two
incandescent lamps must be connected in series in each supply phase.
Alternatively, use three resistors of 1 kΩ / 160 W each (e.g. GWK200J1001KLX000 from
Vishay) instead of the incandescent lamps.
● 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.

WARNING
Electric shock when lamp sockets are installed so that they are not insulated
If two incandescent lamps connected in series are used, the insulation of the lamp
sockets is not designed for a high voltage of 3 AC 500 to 690 V. Touching live parts can
result in death or serious injury.
• For a line voltage of 500 to 690 V 3-ph AC, install the two lamp sockets connected in
series so that they are carefully insulated - and protect them so that they cannot be
touched.
