4.2 MOUNTING
Lead all cables and wires you want to connect to the device through the mounting housing (for retrofit version:
through the hole in the existing panel).
4.1 DISASSEMBLING THE FRONT PANEL
(APPLIES ONLY TO THE SURFACE-MOUNTED AND FLUSH-MOUNTED MODEL)
Remove the front panel with the attached Main Electrical Unit carefully from the mounting housing (backbox)
using the orange (Torx+Pin) screw driver provided.
We have designed the front panel and the safety screw in a way that it cannot be screwed through the
front panel so that is does not fall off / get lost during installation..
Turn the safety screw counter-clockwise until it is loose. Pull the front panel with attached Main
Electrical Unit out of the mounting housing (backbox).
Flush-mounted model Surface-mounted model
Please make sure that the outer frame of the flush-
mounted housing rests on the outside of the wall
and that the edge of the flush-mounted housing
is sealed all around against moisture from the
outside.
Before mounting: Pierce through the middle
of the rubber seal for the cable entry using a
screwdriver.
