ARS*-B2-IA* Product Description Product Description 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.

Figure 2.4 The rail field switches provide 2 sockets for small form-factor pluggable (SFP) transceiver Ethernet modules. Pepperl+Fuchs' SFP transceivers are intended to be used in applications, where extended distances are required. The SFP transceivers fulfill enhanced requirements for industrial use as such as installation in explosion-hazardous area, extended temperature range, and enhanced electromagnetic compatibility (EMC).

ARS*-B2-IA* Product Description Wall Mounting Kit 22.4 Figure 2.8 A wall mounting kit is provided as an accessory. The kit includes 2 brackets. The factory- installed DIN mounting rail clamps must be removed before installing. Scope of Delivery The rail field switch is delivered with mounting brackets for DIN mounting rail. Technical data Depending on the mounting position of the rail field switch and the use of SFP transceivers, the maximum ambient temperature of the rail field switches is reduced.

ARS*-B2-IA* Installation Installation General Installation Information 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.
ARS*-B2-IA* Installation 6-pole auxiliary power connector The isolation of installed wires must finish at the terminal cage. Alternatively, isolated wire end ferrules can be used. The terminal cages of unused terminal connections for PWR A and PWR B must be covered, for example, with isolated wire end ferrules.

ARS*-B2-IA* Installation Pick the SFP transceiver and carefully remove it from the socket. Install a new SFP transceiver or put a protective cover onto the SFP socket of the rail field switch. Mounting or Dismounting Separation Wall 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.
