If the limit value of the potential jumpers U
M
and U
S
is reached (total current of U
S
and U
M
),
a new power terminal must be used.
For the behavior of the safety module in the event of an error at the supply voltage, please
refer to Section “Supply voltage errors” on page 72.

DC distribution network according to IEC 61326-3-1:
A DC distribution network is a DC power supply network that 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 intended for a typical sys-
tem or machine distribution, the DC connections are viewed and tested as I/O signals ac-
cording to IEC 61326-3-1.
NOTE: Module damage due to polarity reversal
Polarity reversal places a burden on the electronics and, despite protection against polar-
ity reversal, can damage the module. Therefore, polarity reversal must be prevented.

WARNING: Loss of functional safety due to parasitic voltages
Supply the supply voltages U

and U
S
at a bus coupler and/or a power terminal from the
same power supply unit, so that the loads of IB IL 24 PSDO 8-PAC are not affected by par-
asitic 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.
