6.3 Busbars for the supply voltages
The supply module supplies the power for the axis modules separately for
the control section and DC link. The control section receives its 24 V supply
from switched­mode power supply in the supply module via the upper bus­
bar (+24V DC and GND). The DC link supply comes from an unregulated
DC voltage and is connected to the axis modules via the lower busbar (DC
Link +/­).
1) Make sure the supply unit is arranged in a line with all axis modules and
they are together in a row.
2) Use the busbar elements supplied for the power supply for the axis mod­
ule. Connect together all (+24 V DC) connections and all (GND) connec­
tions.
3) Use the busbar elements supplied for the DC link supply for the axis
module. Connect together all (DC Link+) connections and all (DC Link­)
connections.
Caution
The busbars supplied are to be used for the electrical coupling of the de­
vices. On the usage of connection elements that do not meet the require­
ments, KEBA does provide any guarantee for stable, reliable operation.
