Power supply

In its basic configuration, the industrial PC is equipped with a 100-240 V AC, 50-60 Hz full-range power
supply unit.

The power supply is connected via the IEC socket (X101) on the rear side of the industrial PC. The
assignment includes a protective conductor (1), a neutral conductor (2) and an outer conductor (2) (see Fig.
4).

Optionally, you can order the industrial PC with a 24 V DC power supply unit. In this case, the industrial PC
is supplied with a nominal voltage of 24 V. The power supply (X101) is connected via a 5-pin socket. The
external wiring (X102) of the industrial PC is done via a 3-pin socket.
The main supply voltage is applied between PIN 1 (24 V) and PIN 2 (0 V) of the power supply socket (X101).
If the industrial PC is equipped with an integrated uninterruptible power supply (UPS), you can also connect
an external battery pack to PIN 4 and 5.

The positive pole of the supply voltage at PIN 1 of the power supply socket (X101) is looped through to PIN 3
of the socket (X102). PIN 3 thus serves as the positive pole for PC-ON.
