2.4.2 Supply v24 VDC
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 PP500 housing.
The supply voltage is protected internally by a soldered fuse (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).
The device must be returned to B&R for repairs if the fuse is blown because of an error.

2.4.2.1 Ground
Caution!
The pin's connection to the functional ground (pin 2) should be as short as possible
(e.g. in the control cabinet). We recommend using the largest possible conductor
cross section on the supply plug.
The grounding connection is located on the back of the PP500 systems.

The M4 self-locking nut can be used, for example, to fasten a copper strip that is built into
the PP500 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).
