Mounting and Wiring
General description
The N-system DIN-rail device (2 SUs) can be installed to
N-system distribution boards, surface or flush mounted,
or to any DIN-rail EN 50022-35 x 7,5 available that has a
data rail installed.
The connection to the bus line is established by clicking
the device onto the DIN-rail (with a data rail installed).
Take care that the type plates of all devices on a DIN-rail
can be read in the same direction, guaranteeing the
devices are polarised correctly.
Mounting DIN-rail devices (Figure 2)
-
Slide the device (B1) onto the DIN-rail (B2) and
-
swivel back the device until the slide clicks into place
audibly.
Dismounting DIN-rail devices (Figure 2)
-
Remove all connected wires,
-
press down the slide (C3) with a screw-driver and
-
swivel the device (C1) from the DIN-rail (C2).
