3.2.1 Power supply
The Panel PC is supplied with a nominal voltage of 24 V. The power supply and the protective earth of the
PC are connected via the five-pin voltage socket (X101). The main supply voltage is applied between PIN 4
(0 V) and PIN 5 (24 V) of the socket. If the Panel PC is equipped with an internal, capacitive 1-second UPS
(uninterruptible power supply), this is also supplied via the voltage. The 1-second UPS does not serve to
back-up the operating system.
