Overview
SITOP UPS modules can continue operation of the PCU 50.5 temporarily if a power failure
occurs and/or shut down the system properly.
For example, a SITOP UPS module also protects against data loss when the PCU 50.5
hardware is shut down, because for technical reasons with Windows-based systems, data is
still written to the SSD after shutdown.
● You will find general information about SITOP UPS modules used in combination with the
PCU base software in Section SITOP modules for the PCU 50.5 (Page 62).
● If you want to use a SITOP UPS module in combination with the PCU base software, you
must first adapt the settings of the SITOP software (Page 64).
● Optionally, you can adapt the delay time after which the HMI software will be forced to
shut down (Page 67).
● You must configure the hardware (Page 69) of the SITOP UPS module before using it
with the PCU base software.
2.4.1 SITOP modules for the PCU 50.5
Suitable SITOP UPS modules
SITOP UPS modules can continue operation of the PCU 50.5 temporarily if a power failure
occurs and/or shut down the system properly.
In conjunction with the PCU base software, all specific applications are taken into account
(e.g. HMI software) with the
Safe shutdown after a power failure of the delivery condition of the PCU 50.5 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.
