Connection of supply voltages via busbars
The voltage supply to the axis module is separate for the control and power
sections. The control section receives its 24 V supply from switched-mode
power supply in the supply module via the upper busbar (+24V DC and
GND).
The power section in the axis module receives its DC link supply from the
supply module via the lower busbar (DC-Link+ and DC Link-).
1) First make sure that all D3-DA 3xx/x axis modules with the D3-DP 3xx/x
supply module are arranged in a line and are in contact with each other.
2) Always first connect the 24 V power supply for the axis module.
For this purpose use the pre-assembled busbar elements. To be able to
rotate the busbar elements it is necessary to unscrew the screws
slightly.
3) Only connect the DC link supply for the axis modules when you want to
place the axis modules in operation. If you want to use several axis mod-
ules, all DC Link+ connections and all DC Link- connections must be
connected together.
For this purpose also use the pre-assembled busbar elements. To be
able to rotate the busbar elements it is necessary to unscrew the screws
slightly.
Caution
Once all busbar elements have been fitted, make sure that all connections
have good contact and are sufficiently secure (2.1 Nm / 18.5 lb-in) that they
cannot come loose. On the usage of connection elements that do not meet
the requirements, KEBA does provide any guarantee for stable, reliable op-
eration. Also expires certification marks and CE conformity.

Information
You will find more detailed information on the mains connections for the
supply module in the Project Manual for the D3-DP 3xx/x supply module.
