2.4 Connecting the power supply
The system bus communication channel on the XN300 slice modules is
powered with the 5 V on the system bus.
Power is delivered either through the XControl modular PLC being used or
through the gateway.
To find out the maximum I
BP_5V
current drawn per XN300 slice module,
please refer to the table in the appendix in  Section “39.4.4 Current draw
per XN300 slice module on the 5 V system bus”, page 335.
For information on the delivered current, please refer to  Section “39.4.3
Delivery of power on the system bus”, page 334.
In addition, the system bus provides a 24 VDC supply voltage used to
internally power the XN300 slice modules.
To find out the maximum I
BP_24V
current drawn per XN300 slice module,
please refer to the table in the appendix in  Section “39.4.5 Current draw
per XN300 slice module on the 24 V system bus”, page 337.
Modules with high power consumption levels, however, will also need an
additional power supply.
The following XN300 slice modules require an external 24 VDC power supply
as well:

DANGER
In safety-relevant applications, the power supply used to power
the XN300 system must be a PELV power supply unit.

CAUTION
Make sure not to exceed the maximum total current for all the
XN300 slice modules.
The total current for the +5 V power supply must not exceed
the current delivered by the XControl modular PLC or the gate-
way!
The total current for the +24 V power supply must not exceed
the current delivered by the XControl modular PLC or the gate-
way!
