8.3 Connecting power supply and internal control cables
You might need to establish the fibre cable connections from the star coupler board to the power module.
Connect the cables according to Figure 8-11.
The control unit uses 24 VDC supplied from the ASIC board, which is located on the left side of the power
unit 1. To access the board, remove the protective cover in front of the power module. Connect the power
supply cable to the X10 connector on the ASIC board and to the X2 connector on the rear side of the control
unit.
Figure 8-10. Connecting the power supply and control cables to the control unit, FR12
Each fibre optic cable has a number 1...8 and 11…18 marked on the cable shield at both cable ends.
Connect each cable to the connectors marked with the same number on the ASIC board and on the rear
side of the control unit. Additionally, you may have to connect the 4 fibre cables from the feedback board to
the star coupler board. The list of the optic signals can be found in chapter 8.4.
CAUTION! Be careful when connecting the fibre optic cables! Connecting the wires incorrectly will
damage power electronic components.
NOTE!
The minimum bending radius for optical cables is 50mm.
Fix the cable bundle at two or more points, at least one at each end, to prevent damages to the cables.
Fasten the protective cover on the power unit when the work is finished.
