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 mm
2
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 The power supply must be protected with 16 A.
PC_ON, Power-Status
The circuit for shutting down the Industrial PC is realized using the input-
signal
PC_ON and the output-signal Power-Status :
•
The PC starts shutting down if 24 V exists at PC_ON , for example
using a switch.
•
After shutting down, there is an output-voltage of 24 V at Power-
Status . This allows for example connecting an air gap switch for
disconnecting the system from power supply.
