Installation and wiring
General description
The DIN rail mounted device in N-system dimensions
(width 6 module units) can be inserted in N-system dis-
tribution boards, surface- or flush-mounted and wher-
ever DIN rails according to EN 60715-TH35-7.5 are pre-
sent. The connection with the bus line is either carried
out via a bus terminal or via the contact system to the
data rail.
Installing the DIN rail mounted device (Figure 2)
-
Suspend the DIN rail mounted device (B 1) on the DIN
rail (B2) and
-
Rotate the DIN rail mounted device (B1) backwards un-
til the slide switch audibly clicks into position.
Dismantling the DIN rail mounted device (Figure 2)
-
Remove all connected cables
-
Press the slide switch (C3) downwards with a screw-
driver and
-
Remove the DIN rail mounted device (C1) from the DIN
rail (C2) with a swivel action.

Removing the bus terminal (Figure 3)
-
The bus terminal (D2) is located on the upper side of
the binary input device N 262E11 (D1).
-
The bus terminal (D2) consists of two sections (D2.1,
D2.2) each with four terminal contacts. Care should be
taken not to damage the two test sockets (D2.3) either
by accidentally trying to put in the bus cable or with
the screwdriver (when trying to remove the bus termi-
nal).
-
Carefully insert the screwdriver into the wire entry slot
underneath the bus terminal (D2) and pull the bus
terminal (D2) forwards out of the binary input device
(D1).
Note:
Care should be taken as there is a risk of shorting the bus
pins with the screwdriver!
