5.2.3 Connect battery pack
Together with the CX2100-0914 power supply unit, the CX2900-0192 battery pack is capable of supplying
power to the Embedded PC in case of power failures. The power supply unit and the battery pack are
connected to each other by two cables. In normal operation the battery pack is charged by the power supply
unit. In the event of a power failure the battery pack supplies the Embedded PC with power via the power
supply unit.
If a further device such as a control panel or monitor is connected to the X940 OUT connection (+24 V, 0 V,
earth), this device will also be supplied with power by the battery pack in the event of a power failure (see:
