Connection of External Backup Battery Infeed
Here, you can see the position of this interface on the slot bracket.
A lithium cell (AA size, 3.6 V) is used for the backup battery supply of the
CPU 41x-2 PCI .
The WinAC Slot 41x package includes a battery pack with a suitable backup
battery and a battery holder.
A 2-pin, 4.95 mm socket is provided on the slot bracket of the CPU 41x-2 PCI for
infeed purposes. This socket is available for an SO connector without sliding
sleeve per DIN 45323 for connection of external power sources for battery-fed
devices.
However, the assignment does not correspond to DIN, i.e., the inner contact is the
positive pole and the outer contact is the negative pole. As a result, a short circuit
with the slot bracket of the CPU does not occur when the connector to the backup
battery is removed/inserted.
