WARNING
Loss of functional safety due to parasitic voltages
Supply the supply voltages U
M
and U
S
at a bus coupler and/or a power terminal from the
same power supply unit, so that the loads of IC220SDL963 are not affected by parasitic
voltages in the event of an error.
Note:
Damage to module electronics in the event of surge voltage
Do not use a DC distribution network.
DC distribution network according to IEC 61326-3-1:
A DC distribution network is a DC power supply network, which supplies a complete
industrial hall with DC voltage and to which any device can be connected. A typical system
or machine distribution is not a DC distribution network. For devices that are provided for a
typical system or machine distribution, the DC connections are viewed and tested as I/O
signals according to IEC 61326-3-1.

Terminal point assignment
Figure 5: Terminal point assignment
The VersaPoint connectors are supplied with the module. They are coded and marked
accordingly for connection to prevent polarity reversal. If other connectors are used
according to the ordering data, they must also be coded.
