2.4.2 Supply voltage
The Panel PC can be operated with 24 VDC or optionally with 100~240 VAC. The 5AC902.PS00-00 power supply
is needed for AC power.
Information on installing or exchanging the power supply can be found under "Installing or replacing the AC power
supply" on page 137.
Danger!
• All supply voltage must be disconnected before removing device covers or components or
removing/installing accessories, hardware or cables.
• The power cable must be disconnected from the device and from the voltage supply.
• Before the device can be connected to the power supply and turned on, all covers, components,
accessories, hardware and cables must be installed or attached.
2.4.2.1 +24 VDC power supply
The 3-pin male connector required for the supply voltage connection 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. 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.

2.4.2.1.1 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 on the bottom of the Panel PC system.
The ground connection can 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.
