● 12 incandescent lamps 120 V / 50 W for a line voltage of 500 to 690 V 3 ph. AC, where 4
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.
● Various small components, such as lamp sockets, cable #16 AWG (1.5 mm²), etc.
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
Risk of death from electric shock when installation of lamp sockets is non-insulated
If two incandescent lamps connected in series are used, the insulation of the lamp
sockets is not rated for the high voltage of 500 to 690 V 3 ph AC.
• For a line voltage of 500 to 690 V 3 ph AC, install the two lamp sockets connected in
series with insulation and protect them from being touched.
