Power supply

The panel PC is supplied with a nominal voltage of 24 V. The power supply and the protective earth of the
device are connected via the 8-pin voltage socket (X110). The main supply voltage is applied between PIN 5
(0 V) and PIN 6 (24 V) of the socket. If the panel PC is equipped with an integrated uninterruptible power
supply (UPS), an external battery pack can additionally be connected to PIN 1 and PIN 2. Beckhoff offers the
C9900-U330 battery pack for this purpose.
