2.4.6 Supply voltage
The PPC700 system units have a 24 VDC ATX compatible power supply.
The 3-pin socket required for the supply voltage connection is not included in delivery. This can
be ordered from B&R using the model number 0TB103.9 (screw clamp) or 0TB103.91 (cage
clamp).
The pin assignments can be found either in the following table or printed on the Panel PC 700
housing. The supply voltage is internally protected (10A, fast-acting), so that the device cannot
be damaged if there is an overload (fuse replacement necessary) or if the voltage supply is
connected incorrectly (reverse polarity protection - fuse replacement not necessary).
Ground
PPC700 systems are equipped with a ground connection. The M4 self-locking nut must be used,
for example, to fasten a copper strip that is built into the PPC700 at a central grounding point in
the control cabinet or system. The largest possible conductor cross section should be used (at
least 2.5 mm²).

Warning!
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).
