2.6.1 +24 VDC power 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 clamp) or 0TB103.91 (cage clamp).
The pinout is listed in the following table and printed on the PPC800 housing. 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 replace-
ment not necessary). The device must be returned to B&R for repairs if the fuse is blown in the event of an error.

2.6.1.1 Grounding
Caution!
The functional ground (pin 2) must be connected to ground (e.g. control cabinet) using the shortest
possible path. Using the largest possible conductor cross section on the supply connector is recom-
mended.
The ground connection is located at the top right on the back of the PPC800 system.
Ground connection
Figure 11: Ground connection
The M4 self-locking nut can be used, for example, to fasten a copper strip to a central grounding point in the control
cabinet or system where the PPC800 is installed. The largest possible conductor cross section should be used
(at least 2.5 mm²).
