PIN 5 and 6 of the battery pack are available for looping through a 24 V power supply to the PC. 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 the battery pack to the PC with an eight-core sheathed cable.
If the supply voltage fails, the PC draws the voltage from the charged battery pack, which saves the data and
allows the PC to shut down properly.
The intended wiring of the battery pack can be found in the wiring diagram in Figure 13.
