5.6.5 Installing the power supply unit
Carefully push the power supply unit into the housing until it reaches the stop.
Use the hexagon socket-head screw to secure the unit at the bottom.
Check that the yellow-green PE wire is connected to the cover.
Replace the cover.
PLEASE NOTE: 5
Make sure that the actuating shaft of the main switch slides easily into the opening in the ro-
tary button. 5
Fix the cover in place using the two hexagon socket head screws.
