Product Description
2 Product Description
2.1 Overview and Application
The Ethernet-APL series of Rail Field Switches are ruggedized, managed switches. The rail
field switches provide connectivity for Ethernet-APL and optionally PROFIBUS PA field devices
to 100/1000-MBit/s industrial Ethernet networks. Port diagnostics facilitate fault finding in
Ethernet-APL networks and providing information for preventive maintenance of the rail field
switches and the network they are connected to.The rail field switches are managed with an
integrated web server.
The rail field switches are suitable for DIN rail mounting or wall mounting.The rail field switches
can be installed in the explosion hazardous Zone 2. The spur connections of the rail field
switches provide power to the connected field devices and are rated intrinsically safe Ex ia IIC
for Zone 1/0 and Zone 20 mounting. The spurs are compatible with the Ethernet-APL port
profile SPAA. 2 RJ45 and 2 SFP Ethernet interfaces permit the connection to industrial Ether-
net networks like PROFINET or EtherNet/IP. 2 of the 4 ports may be used in ring configuration.
Fiber optic small form-factor pluggable (SFP) transceivers are available as accessories. Prod-
uct versions with pluggable screw terminals and spring terminals are available.

3 Installation
3.1 General Installation Information
The device can get very hot during operation. To protect the device from excessive heating,
observe the required clearances and sufficient ventilation when installing the device.
Danger!
Explosion hazard from damaged electronic components
Premature wear of electronic components in a device that was previously used in a general
electrical installation can cause sparks that can ignite the surrounding potentially explosive
atmosphere.
Never install devices that have already been operated in general electrical installations in elec-
trical installations used in combination with hazardous areas!
Danger!
Explosion hazard from exposure to potentially explosive gas atmosphere
If the device is installed in Zone 2 without mounting it in a sufficiently suitable
surrounding enclosure, gas, dust, water or other external interferences can cause the live
device to spark. The sparks can ignite the surrounding potentially explosive atmosphere.
Mount the device in a surrounding enclosure that complies with the requirements for surround-
ing enclosures according to IEC/EN 60079–0, and that is rated with the degree of
protection IP54 according to IEC/EN 60529.The surrounding enclosure must have an
EU declaration of conformity according to the ATEX Directive for at least
equipment protection level Gc.
Danger!
Explosion hazard from exposure to potentially explosive dust atmosphere
If the device is installed in Zone 22 without mounting it in a sufficiently suitable
surrounding enclosure, dust, water or other external interferences can cause the live device to
spark.The sparks can ignite the surrounding potentially explosive atmosphere.
Only mount the device in a suitable surrounding enclosure. The surrounding enclosure must
have an EU declaration of conformity according to the ATEX Directive for at least equipment
protection level Dc.

Mounting DIN mounting rail
The rail field switches are designed for mounting on a 35 mm DIN mounting rail in accordance
with EN 50022.
Figure 3.1
1. Position the rail field switch on the DIN mounting rail.
2. Use the bottom hook in order to hook the electronics onto the DIN mounting rail.
3. Move the top hook over the upper end of the DIN mounting rail until the locking mechanism
engages.

Inserting or Removing Fiber Optic SFP Transceiver
In explosion hazardous areas only use SFP transceivers listed in the SFP transceiver certificate
that is referenced in the certificate of this product.
Ensure to cover unused SFP transceivers slots with the provided dust protection caps.
Inserting fiber optic SFP transceiver
1. If installed, pull the protective cover from the SFP socket on the rail field switch.
2. Line-up the SFP transceiver and insert it into the socket of port P3 or P4. The transceiver is fully
seated when you hear a click.
3. Remove the dust protection cap from the SFP transceiver.
4. Insert the LC connector of the fiber optic cable into the SFP transceiver.
Removing fiber optic SFP transceiver
1. Disconnect the LC connector from the SFP transceiver.
2. Open the bale clasp on the SFP transceiver by pushing it into downward direction with your
index finger. If the bale clasp is obstructed and you cannot use your index finger to open it, use
a small slot-head screwdriver to open the bale clasp.
3. Insert a dust protection cap into the SFP transceiver.
Danger!
Explosion hazard from sparking when using operating elements!
Using operating elements in a potentially explosive atmosphere can cause sparks that can
ignite the surrounding atmosphere.
•While power is on, do not insert and remove SFP transceivers.
•When installing or removing SFP transceivers, make sure that power is removed.
•Only use operating elements (e.g., switch, slider, button, etc.) in the absence of a poten-
tially explosive atmosphere.
Danger!
Explosion hazard from electrostatic charge!
Electrostatic charges can discharge and consequently ignite a surrounding potentially explo-
sive atmosphere while installing or operating the device.
•Avoid electrostatic charges during installation and operation of the device.
•Observe electrostatic discharge (ESD) precautions.
•Wear an antistatic wrist or ankle strap that connects to an approved grounding source.
Note
Verify that the SFP transceiver is completely seated and secured in its
assigned socket on the rail field switch by firmly pushing on the SFP
transceiver. If the SFP transceiver is not completely seated and secured in the
receptacle, you will hear a click as the triangular pin on the bottom of the SFP
transceiver snaps into the hole in the receptacle.

ARS*-B2-IA*
Installation
4. Pick the SFP transceiver and carefully remove it from the socket.
5. Install a new SFP transceiver or put a protective cover onto the SFP socket of the rail field
switch.
Mounting or Dismounting Separation Wall
Mounting separation wall
To provide clearance distance of 50 mm between the non-intrinsically safe circuits and intrinsi-
cally safe circuits, install the separation walls.
Figure 3.5
1. Press the separation walls into the provided slots on the front of the rail field switch.
2. Make sure that they are locked in place.
Danger!
Explosion hazard from wrong separation distances!
If you do not observe the minimum separation distances between intrinsically safe circuits of
associated apparatus and non-intrinsically safe circuits, this can lead to added currents or volt-
ages. This can result in current/voltage flashover generating sparks.The sparks can ignite the
surrounding potentially explosive atmosphere.
Ensure that you observe the compliance of the separation distances to all non-intrinsically safe
circuits according to IEC/EN 60079-14.
