2 Assembly and start-up
The devices have been developed for practical application in a harsh
industrial environment. The installation process is correspondingly simple.
On delivery, the device is ready for operation.
The following steps should be performed to install and configure a switch:
Unpacking and checking
Insert data in label area
Connect the terminal block for voltage supply and signal 
contact and connect the supply voltage
Install the device on the DIN rail, grounding
Install the terminal block, start-up procedure
Connecting the data lines
2.1 Installing the device
2.1.1 Unpacking and checking
Check that the contents of the package are complete (see page 25
“Scope of delivery”).
Check the individual parts for transport damage.
2.1.2 Insert data in label area
The information field for the IP address on the front of the device helps you
to structure your network installation clearly.

2.1.3 Connecting the terminal blocks for supply voltage
and signal contact
The supply voltage and the signal contact are connected via a 6-pin terminal
block with a snap lock.
Caution!
Note the safety instructions (see page 4 “Notes on safety”) and only
connect a supply voltage that corresponds to the type plate of your
device. Make sure that the contact load capability of the signal
contact is not exceeded (see page 24 “Technical data”).
Supply voltage
Redundant power supplies can be used. Both inputs are uncoupled.
There is no distributed load. With redundant supply, the power supply unit
supplies the device only with the higher output voltage. The supply
voltage is electrically isolated from the housing.
You can choose between DC or AC voltage when connecting the supply
voltage. You use the +24V and 0V pins to connect the AC voltage (see
fig. 4).

1 – DC voltage, voltage range: 9.6 V DC to 60 V DC 
2 – AC voltage, voltage range: 18 V AC to 30 V AC
Note: With non-redundant supply of the main voltage, the device reports
a loss of power. You can avert this message by applying the supply
voltage via both inputs, or by changing the configuration in the
Management.
“FAULT” signal contact
The signal contact (“FAULT”, for pin assignment of terminal block, see
fig. 4) monitors the functioning of the device, thus enabling remote
diagnostics. You can specify the type of function monitoring in the
Management.
You can also use the switch Web page to switch the signal contact
manually and thus control external devices.
A break in contact is used to report the following conditions via the
potential-free signal contact (relay contact, closed circuit):
The detected inoperability of at least one of the two voltage supplies
(voltage supply 1 or 2 is below the threshold value).
A continuous malfunction in the device.
The loss of connection at at least one port. The report of the link status
can be masked by the Management for each port. In the delivery state,
link status monitoring is deactivated.
The loss of ring redundancy reserve.
A detected error during the self-test.
Pull the terminal block off the device and connect the power supply
and signal lines.
2.1.4 Installing the device on the DIN rail, grounding
Mounting on the DIN rail
Mount the device on a 35 mm DIN rail in accordance with DIN EN
60175.
Attach the upper snap-in guide of the device into the DIN rail and press
it down against the DIN rail until it snaps into place.

2.1.6 Installing the terminal block, start-up procedure
Mount the terminal block for the voltage supply and signal contact on the
front of the device using the snap lock. Make sure that the snap lock
snaps into place.
Connecting the voltage supply via the terminal block starts the operation of
the device.
2.1.7 Connecting the data lines
You can connect terminal devices and other segments at the ports of the
device via twisted pair cables or F/O cables.
Install the data lines according to your requirements.
10/100 Mbit/s twisted pair connection
These connections are RJ45 sockets.
10/100 Mbit/s TP ports enable the connection of terminal devices or
independent network segments according to the IEEE 802.3 10BASE-T/
100BASE-TX standard. 
These ports support:
Autonegotiation
Autopolarity
Autocrossing (if autonegotiation is activated)
100 Mbit/s half-duplex mode, 100 Mbit/s full duplex mode
10 Mbit/s half-duplex mode, 10 Mbit/s full duplex mode
State on delivery: autonegotiation activated.
The socket housing is electrically connected to the front panel.

20 RS20 Basic
Release 17 11/10
100 Mbit/s F/O connection
These connections are DSC connectors.
100 MBit/s F/O ports enable the connection of terminal devices or
independent network segments in compliance with the IEEE 802.3
100BASE-FX standard. 
These ports support:
Full or half duplex mode
State on delivery: full duplex FDX
Note: Make sure that the LH ports are only connected with LH ports, SM
ports are only connected with SM ports, and MM ports only with MM ports.
2.2 Display elements
After the operating voltage is set up, the software starts and initializes itself.
Afterwards, the device performs a self-test. During this process, various
LEDs light up. The process takes around 60 seconds.
Device state
These LEDs provide information about conditions which affect the
operation of the whole device.
