Installation of upper section * Place all assemblies on a level surface. * Push the side parts over the terminal blocks of the equipped printed circuit board; in doing so, the guide pins of the terminal blocks must slide into the drilled holes in the side parts * Snap the front plate onto the premounted side parts 2. Installation of housing * Place all assemblies on a level surface. * Slide the printed circuit board of the upper section into the guide grooves of the base. * When placing the hood and upper section together, ensure that the wall areas overlap correctly. The guide element of the base must slide into the guide recess of the upper section. Notes on Housing Deinstallation 1. Removing the front plate * Insert a screwdriver in the side recess of the front plate. * Turn the screwdriver to the right and left. 2. Removing the upper section * Insert a screwdriver in the snap fastener of the base as far as it will go. * With a tilting movement, release the snap fastening. * Pull the upper section with the printed circuit board out of the base. 5 E.
