4.15.2 SITOP modules for the PCU 50.5
Suitable SITOP UPS modules
SITOP UPS modules can continue operation of a PC system temporarily if a power failure
occurs and/or shut down the system correctly.
In conjunction with the PCU base software, all specific applications are taken into account (e.g.
HMI software) with the USVShutdown.bat component.
Safe shutdown after a power failure of the PCU 50.5 as delivered takes approximately 20
seconds. For a typical power consumption of approx. 60 W, a capacitor-buffered UPS with an
energy storage device of 2.5 kW is recommended for a PCU 50.5. If longer buffer times are
required, then several expansion modules can be connected in a cascade connection.
Example of a SITOP UPS module that can be used (USB):
SITOP 500S (15 A / 2.5 kWs capacitor)
Article no.: 6EP1933-2EC41
Example of a SITOP UPS with Ethernet/PROFINET interface that can be used:
SITOP UPS1600 starter kit
● DC-UPS SITOP UPS1600 24V DC/10A
● SITOP UPS1100 3.2 AH battery module
Article No.: 6EP4134-3AB00-2AP0
Note
Information about the test environment for machine OEMs
The functionality has been tested in the standard configuration with the PCU base software.
When installing add-on or OEM software components, you must check the shutdown
procedure of the entire system and adapt the factory setting (180 seconds).
See: Parameterizing a delay time for quitting the HMI software (Page 57)
