The exterior of the network splitter (see figure 25.2) contains the following:

1External power supply - A connection for an (optional) external power supply. The external power

supply only feeds the tap-offs (see section 25.3.3).

2 Tap-off 1 - A system bus connector for creating a tap-off. The tap-off is protected against short-circuits and has a maximum load of 2.5 A (see

sections 25.2.2 and 25.3.2).

3System bus - A system bus connector for looping through the main branch (see section 25.3.2).

4 Lid - A lid that provides access to the jumpers (see section 25.2.2). The rear side of the lid contains a label with explanation about the internal settings.

5 Fault LED - A yellow fault LED that provides information about the status of the network splitter (see section 25.5).

6 Power LED - A green power LED that provides information about the status of the network splitter (see section 25.5).

7Tap-off 2 - A system bus connector for creating a tap-off. The tap-off is protected against short-circuits and has a maximum load of 2.5 A (see

sections 25.2.2 and 25.3.2).

8System bus - A system bus connector for looping through the main branch (see section 25.3.2).

Note

It is not allowed to connect more than two other network splitters to a tap-off of a network splitter that is located in the main loop of the network.
