2.1 Device interfaces

The following section provides a description of all interfaces and plugs possible with a
PowerPanel 300 device with BIOS.

2.1.1 Supply voltage

Input voltage: 18 - 30 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 clamps) or 0TB103.91 (cage
clamps).
The pin assignments can be found either in the following table or printed on the Power Panel
plate. The supply voltage is internally protected 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).

Warning!
The pin's connection to the functional ground (pin 2, e.g. switching cabinet) should
be as short as possible. We recommend using the largest possible conductor cross
section on the supply plug.
