Bus termination

The start and end of each fieldbus segment are always to be terminated with a bus terminator. With

various junction boxes (non-Ex), the bus termination can be activated via a switch. If this is not the

case, a separate bus terminator must be installed. Note the following points:

• In the case of a branched bus segment, the device furthest from the segment coupler represents

the end of the bus.

• If the fieldbus is extended with a repeater then the extension must also be terminated at both

ends.
