Ground connection
The RS2-TX is grounded via a separate
screw connection.
2. Configuration
2.1 CONNECTING DTE AND OTHER
NETWORK SEGMENTS
It is possible to connect up to eight data ter-
minal equipments (DTE) or other network
segments to the 10/100 Mbit/s ports of the
RS2-TX using twisted pair cabling (ref. Fig.
4).
3. Assembly, startup procedure
and dismantling
3.1 UNPACKING, CHECKING
Check whether the package was deliver-
ed complete (see scope of delivery).
Check the individual parts for transport
damage.
z
Warning!
Use only undamaged parts!
3.2 ASSEMBLY
The equipment is delivered in a ready-to-
operate condition. The following procedure
is appropriate for assembly:
Check whether the switch pre-setting
suits your requirements (see chap. 1.5).
Pull the terminal block off the RS2-TX
and wire up the supply voltage and indica-
tor lines.
Fit the RS2-TX on a 35 mm standard bar
to DIN EN 50 022.

5pin terminal block
The supply voltage and the indicator
contact are connected via a 5pin terminal
block.

Warning!
The RS2-TX equipment is designed
for operation with a safety extra-low
voltage. Thus, they may only be
connected to the supply voltage
connections with PELV circuits or
alternatively SELV circuits with the
voltage restrictions in accordance
with IEC/EN 60950.
– Voltage supply
: Redundant voltage sup-
plies are supported. Both inputs are
decoupled. There is no load distribution.
With redundant supply, the power pack
supplies the RS2-TX only with the higher
output voltage. The supply voltage is elec-
trically isolated from the housing.
– Indicator contact:
The indicator contact is used to supervise
the functions of the RS2-TX and thus faci-
litates remote diagnosis without manage-
ment software.
Contact interrupt indicates the following
by means of a potential-free indicator
contact (relay contact, closed circuit):
– the failure of at least one of the two
supply voltages.
– a permanent fault in the RS2-TX (inter-
nal 3,3 V DC voltage, supply voltage 1 or
2 < 9.6 V, ...).
– the faulty link status of at least one port.
The indication of the link state on the
RS2-TX can be masked on a port-by-port
basis using the DIP switches LA1 to LA8.
State of delivery: there is no link test.
Note:
In the case of the voltage supply
being routed without redundancy, the RS2-
TX indicates the failure of a supply voltage.
You can prevent this message by feeding in
the supply voltage through both inputs.
Attach the upper snap-on slide bar of
the RS2-TX to the standard bar and press it
down until it locks in position.
Fit the signal lines.
Notes:
– The front panel of the RS2-TX is grounded
via a separate ground connection.
– Do not open the housing.
– The shielding ground of the twisted pair
lines which can be connected is electrical-
ly connected to the front panel.

3.3 STARTUP PROCEDURE
You start up the RS2-TX by connecting
the supply voltage via the 5-pin terminal
block.
3.4 DISMANTLING
To take the RS2-TX off the ISO/DIN rail,
insert a screwdriver horizontally under the
housing into the locking slide, pull it (with-
out tipping the screwdriver) downwards
and lift the RS2-TX upwards.
