Risk of electric shock Dangerous touch voltages can lead to electric shock. To avoid electric shock, observe the following:

Incorrect connection procedure Incorrect procedure when connecting the cable can cause hardware damage.

After you have mounted the battery pack in the control cabinet, you can connect it to the PC.
Grounding
Potential differences are minimized and electrical currents are diverted to the ground through protective earthing or potential equalization of electronic devices. This is to prevent dangerous touch voltages and electromagnetic interference.
Connecting the battery pack
You must connect the battery pack to the PC. For this purpose, there is an 8-pin terminal strip (X101) on the battery pack housing (see Fig. 11).

You can connect two wires on each side of a terminal of the terminal strip. For this purpose, you must use double wire end sleeves (see Fig. 12).
Fig.12: C9900-U332_double wire end sleevePIN 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.
