Remove the intermediate panel with the internal AC/DC voltage converter
from the housing side wall (fig. 28 left).
4
Remove the internal AC/DC voltage converter from the intermediate panel
(fig. 28 right).
5
Remove the colour-coded leads from the screw terminals of the internal
AC/DC voltage converter.
6
Connect the colour-coded leads in their correct assignment (fig. 29) to the
screw terminals to the new internal AC/DC voltage converter and ensure that
the screws have been tightened securely.
7
Reassemble the controller in the reverse order up to the housing cover.
8
The housing cover can be mounted when all preliminary functions work
correctly, i.e. the LED’s light up at switching on.
Ensure that there are no loose parts in the housing.
Check that all screws have been tightened and that there are no screws left
over.
After the work is completed, it is necessary to perform a functional test and
commissioning of the controller.

has been disassembled (fig. 26 and fig. 27)
1
Release and remove the housing cover of the controller.
2
Fully remove the single mounting screw of the fitting panel of the power
supply from the floor of the housing (fig. 30 - 1).
