1. Disconnect the two D -type plugs, and remove the two cables from the demonstration unit.
A brown/blue/earth power cable group also emerges from the blanking plate aperture. Leave this cable group in
place, and retain the blanking plate’s rubber grommet.
2. A thin black/red twisted pair cable is connected near the edge of the PCB by a small two-pin plug (see Figure 5).
Disconnect the plug from the PCB, but do not remove the cable from the demonstration unit; it will be used to
provide power to the new control panel.
