Mounting and wiring
CPX27xx-0010 25 Version: 0.2
5.2.2 Connecting
NOTE
Use the correct fuse
The power supply must be protected with maximum 4 A.
Cable Cross Sections
For the connection of the power supply, wiring with a cable-cross-section of 0.2 … 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.
Check voltage rating and connect
Fitted with the 24 VDC power supply unit:
1. Check that the external power supply is providing the correct voltage.
2. Insert the power supply cable that you have assembled into the Industrial PC's power supply socket.
Then connect it to your external 24 V power supply.
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.
• 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.
