Fig. 17 Cp27Xx_Wiring Diagram C9900-U330 - Beckhoff CP2712 Manual

You can use the UPS output of the power supply unit and connect a Beckhoff Control Panel as a second
display. If the supply voltage fails and the panel PC is only supplied by the battery pack, the control panel
remains in operation. Second display operators can use it to read the power failure notification, back up data,
and shut down the operating system.
In the case of the C9900-U330 battery pack, PIN 4 and 5 of the battery pack are available for looping
through a 24 V supply. Accordingly, you can connect a three-core sheathed cable with plus and minus of the
supply voltage as well as protective earth to the battery pack and then connect to the PC with a five-core
sheathed cable. The method of connecting different components can be taken from the wiring diagram in fig.
