4.5 Replacing the distributor board
To remove the distributor board, the column cladding
must be removed (see chapter Removing the column
cladding).
Document the position of the cables before starting the
disassembly in order to be able to reassemble them later
in their original position.
First remove the electrical wiring. It proves helpful to
document the position of the wiring before dismantling
in order to be able to return it to its original position
afterwards. Then remove the two screws[1] to remove the
distributor board.
The assembly is carried out in the reverse order. Please
note that after the installation of the new distributor
board, the calibration program must be carried out (see
chapter Calibration).
The cable assignment can be taken from the cable diagram.
HAZARD
Danger of electric shock!
Before starting to replace the distributor board, you must put the operating table in a zero-voltage state, otherwise there is a
risk of electric shock.
