2.4.2 +24 VDC voltage supply
The 3-pin male connector required for the power supply interface is not included in delivery. It can be ordered from
B&R using model number 0TB103.9 (screw clamps) or 0TB103.91 (cage clamps).
The pinout is listed in the following table. The supply voltage is protected internally by a soldered fuse (15 A, fast-
acting) to prevent damage to the device in the event of an overload (fuse replacement necessary) or if the voltage
supply is connected incorrectly (reverse polarity protection -> fuse replacement not necessary). The device must
be returned to B&R for repairs if the fuse is blown in the event of an error.

2.4.2.1 Grounding
Caution!
Functional ground (pin 2 of power supply and ground connection) must be kept as short as possible
and connected to the largest possible wire cross section at the central grounding point (e.g. the control
cabinet or system).
The ground connection is located on the interface side of the Panel PC system.
Grounding
The ground connection must be used, for example, to fasten a copper strip to a central grounding point in the
control cabinet or system where the device is installed. The largest possible conductor cross section should be
used (at least 2.5 mm²).
