Mounting and Wiring
General description
The N-system DIN-rail device can be installed in dis-
tribution boards, surface or flush mounted, or on
any DIN rail complying with EN 60715-TH35.
The connection to the bus line is established via a
bus connector terminal (red/black).
The RJ45 socket on the device front side provides
the connection to the Ethernet-IP data network.
Mounting DIN-rail devices (Figure 3)
Slide the device (figure 3, B1) onto the DIN-rail
(figure 3, B2) and
swivel back the device (figure 3, B1) until the
slide clicks into place audibly.
Connect the auxiliary power AC/DC 24V with the
yellow-white bus connector terminal (figure 2,
A1).
Connect the bus line with the black-red bus con-
nector terminal (figure 2, A2).
Plug an Ethernet patch cable with an RJ45 plug
into the RJ45 socket (figure 2, A3) to connect the
device with the LAN / Intranet.
A connection is established to the network when
the yellow LED marked ERR (figure 2, A6) is con-
tinuously lit. When the LED LK (figure 2, A7)
flashes data is sent to or from the device.
Dismounting DIN-rail devices
Unplug the Ethernet patch cable from the RJ45
socket (figure 2, A3).
Remove the yellow-white bus connector terminal
(figure 2, A1) from its socket.
Remove the black-red bus connector terminal
(figure 2, A2) from its socket.
press down the slide (figure 3, C3) with a screw-
driver and
swivel the device (figure 3, C1) from the DIN-rail
(figure 3, C2).
