2.1 Overview and Application
The Ethernet-APL series of Rail Field Switches are ruggedized, managed switches. These
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 Ether-
net-APL networks and providing information for preventive maintenance of the rail field
switches and the network they are connected to.The switches are managed with an integrated
web server.
The switches are suitable for DIN rail mounting or wall mounting. The switches can be installed
in the explosion hazardous Zone 2. The spur connections of the switches provide power to the
connected field devices and are rated intrinsically safe Ex ic IIC for Zone 2 and Zone 22 mount-
ing. The spurs are compatible with the Ethernet-APL port profile SPCC. 2 RJ45 and 2 SFP
Ethernet interfaces permit the connection to industrial Ethernet 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.

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
potentially 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 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.

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 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.
