Power supply

The CPUs of the redundant system have an integrated system power supply. You can add one
load current supply to the integrated system power supply.
NOTE
The CPUs are designed for fixed operation and continuous operation on a load current
supply.
Load power supply (PM)
The load current supply (PM) supplies the system components and CPU. You can install the
load current supply directly to the left of the CPU (without connection to the backplane bus).
Using a SITOP power supply as an alternative to a load power supply
Alternatively, an external 24 V power supply from the SITOP range
(https://mall.industry.siemens.com/mall/en/WW/Catalog/Products/10008864) (SITOP smart or
SITOP modular) can be used:
• With redundant installation
(https://support.industry.siemens.com/cs/ww/en/view/109768676) of the 24 V power
supply as protection against failure of a power supply unit
• With buffering of the 24 V power supply (e.g. with DC UPS) as protection against power
failure
• With selective monitoring of 24 V loads as protection against overload or short-circuit
