Power supply
The panel PC is supplied with a nominal voltage of 24 V.
The power supply and the protective earth of the panel PC are connected via the 12-pin round connector (X101). The cable is routed through the mounting arm adapter. If the panel PC is equipped with an integrated uninterruptible power supply (UPS), an external battery can additionally be connected to PIN 1 and PIN 2. The Beckhoff battery pack C9900-U330 is available for this purpose.
