General description
The N-system DIN-rail device can be installed to N-
system distribution boards, surface or flush mounted, or
to any available DIN-rail EN 50022-35 x 7,5.
During this the electric connection between the clock
controller and the bus coupling unit is established via
the lateral physical external interface (PEI).
The bus coupling unit is not contained in the volume of
delivery and must be ordered separately.

-
swivel back the device until the slide clicks into place
-
audibly.
Remove the protection film of the adhesive tape (B4),
