Beckhoff power supply technology
Schematic diagram of
power supply unit wirings
Innovative solution for
shutting down Industrial
PCs
Industrial PCs equipped with a UPS are in actual use frequently switched
off by simply turning off the supply voltage. In this case the PC shuts down
via the battery. However, over time this reduces the service life of the
battery.
The new Beckhoff power supply technology approach addresses this
problem and now offers the user the option of switching the PC off without
the need for using the battery, thereby reducing the load on the battery.
In addition to the main switch this innovative solution uses an ON/OFF
switch for the machine. Basically, the main switch remains switched on and
provides the power supply for the PC during shutdown. Via the PC ON-
input of the power supply the PC gets the command to shut down the
operating system.
Once the PC has shut down, the PC power supply unit sets the Power
Status-output (P-S) to 0, what indicates that the process is complete and
14 C6930

Installation Instructions
that the main voltage can be switched off. This can be done manually via a
signal lamp connection or via a contactor. With this solution the main
switch generally only has to be switched off if the control cabinet has to be
opened. The battery will only be used in the event of a power failure.
In order to maintain a screen display for the Industrial PC in the event of a
power failure, the power supply unit is equipped with a UPS output 27 V /
1.4 A (max. 2.5 A from 2016 and later) for connecting a Control Panel with
a display dimension up to 19 inches. This enables a power failure to be
visualized and displayed to the user. Once the PC has shut down, the UPS
output is switched off.
For a detailed functional description please refer to section Connecting
Power Supply.
Pin assignment of the connector
The power supply and the external circuit for switching the Industrial PC on
and off are connected via the 8-pole plug connector .

Installation Instructions
Connecting Power Supply
The external wiring consists of the connection of the power supply, the
battery pack (optional) and the connection of customized components for
shutting down the PC.
Cable Cross Sections
Note cable cross sections,
avoid voltage drop!
For the connection of the power supply, wiring with a cable-cross-section
of 1.5 mm2 must be used.
With bigger distances between voltage source and PC, you take the
voltage drop as a function of the cable-cross-section as well as voltage
fluctuations of your distribution voltage into account, so that is secured that
the voltage doesn't fall under 22 V at the power supply.
Insert fuse
Attention
The power supply must be protected with maximum 16 A.
Configuration for shutting down the PC
The connections for shutting down the Industrial PCs are established via
the PC_ON input and the Power Status output.
PC_ON and Power Status functions
• If the PC_ON input is connected to 24 V via a switch, the PC shuts
down according to the rules. The PC_ON signal is inverted, i.e. the
PC shuts down if the 24 V connection is live.
• If the PC_ON input is NOT connected by the user, the PC can be
booted in the familiar way by connecting the supply voltage and shut
down via the battery by switching off the supply voltage.
Service life of the rechargeable battery
Attention
This procedure significantly reduces the service life of the rechargeable
battery and should therefore not be used.
• Once the PC has shut down, the Power Status output is switched
from 24 V to 0 V. Via this output a signal lamp can be connected or a
contactor for de-energizing the whole system. The maximum load for
the Power Status output is 0.5 A and a suitable fuse should be
provided.
C6930 17

Installation Instructions
UPS output
In order to maintain a screen display for the PC in the event of a power
failure, the power supply unit is equipped with a UPS output for connecting
a Control Panel. The maximum load for the output is 1.4 A (max. 2.5 A
from 2016 and later).
UPS output function
• The 27 V DC connection at the UPS output is live even after a power
failure. The maximum load is 1.4 A (max. 2.5 A from 2016 and later).
• Once the PC has been de-energized via the UPS software, the UPS
output is switched to 0 V. Any connected panel is thus switched off,
and total discharge of the rechargeable battery is prevented.
