Chapter 4: 8580/8590 Installation
Installing Connecting Cables
THERE ARE TWO POWER INPUT VERSIONS FOR THE 8580/8590; SPECIAL
PRECAUTIONS MUST BE CONSIDERED WHEN CONNECTING POWER TO
THE TERMINAL!
If 12V is connected to a 24/48 V 8580/8590, the vehicle-mount will not start up, but the unit
will not be damaged.
If more than 16V is connected to a 12V 8580/8590, the vehicle-mount WILL BE DAM-
AGED; THE UNIT WILL NO LONGER FUNCTION.

Installing Connecting Cables
If possible, use the connecting cables supplied to connect the 8580/8590 to the power
supply. Make sure that the connecting cables are laid without kinks and are protected.
4.4
Vehicle Applications (such as Forklifts)
Pay special attention to the various electrical potentials when installing the unit on a vehicle
(such as a forklift). In the 8580/8590, the logic ground and the device enclosure are galvani-
cally connected.
The "logic ground" is the earth line (GND) for all of the internal electrical components, such
as the hard drive and the CPU. It is also the ground reference for supply and signal voltages
that the 8580/8590 provides to external devices via the COM port, the USB connectors and
the keyboard/mouse connector.
