6.5
Establishing an additional ground connection
The power supply system fulfills the requirements relating to electromagnetic compatibility
(noise emission, noise immunity) as described under Safety, approvals, EMC (Page 241).
This also applies to the optional expansion modules.
For larger system configurations, i.e. involving a basic device and several expansion
modules, it may make sense, depending on the actual application, to establish an additional
ground connection between the basic device and expansion modules to increase the noise
immunity and to reduce noise emission.
Route the additional ground connection from terminal "0V" of the basic device to terminal
"GND" of the first expansion module, and from there, to additional expansion modules by
looping through the cable as shown in the diagram below.
The possible wire/conductor cross-section for the additional ground connection is max.
2.5 mm
2
.
NOTICE
Overload of the wiring
It is not permissible to use the "GND" terminals of the expansion modules for the
connection to the common collection point of the 0 V potential of the loads to be supplied
(for example, 0 V rail of the plant or system).
Only establish the connection between the power supply system and the common
collection point of the 0 V potential via terminal "0V" of the basic device.
See also Connections and terminal designations (Page 21).
