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. The main supply voltage is applied between pins 5 (0 V) and 6 (24 V). 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 option C9900-U330 is available for this purpose.
