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 0.5 … 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.
