7.7 Installing and configuring the field multiplexer
system
7.7.1 Basic information for installation
As a rule, follow the instructions of the IL SYS INST UM E when installing the field
multiplexer and the connected Inline terminals.
Observe in particular the following points during installation:
Disconnect the power! Before setting up a field multiplexer station or inserting a terminal into a station, ensure that
the entire station is disconnected from the power. Make sure the entire station is
reassembled before switching the power back on.
Order of the Inline
terminals
Install analog terminals in a field multiplexer station to the right of digital terminals, as
otherwise the field multiplexer station reports a configuration error and the field multiplexer
system is not ready for operation. For later extensions, insert digital terminals before analog
terminals.
FE connection To ensure reliable grounding of the field multiplexer station, ground the field multiplexer
through the FE connection. Connect the terminal points for the FE connection to a grounded
PE terminal (e.g., USLKG 5 universal ground terminal block, Order No. 0441504, see also
Figure 3-1 “Additional grounding of the field multiplexer”).
End plate Terminate each field multiplexer station with an end plate. It is supplied as standard with the
field multiplexer.
End clamp Lock every field multiplexer station with end clamps at the beginning and the end of the
station (see Section “Ordering data” on page 65).
Electrical isolation If you want to set up various electrically isolated areas within a field multiplexer station, use
additional power terminals that draw their current from separate power supplies.
I/O terminals For information about the connection of I/O terminals and of sensors and actuators, please
refer to IL SYS INST UM E user manual and the terminal-specific data sheets.
