Warning: Carefully read the following warnings!
• Never connect a 12 VDC device to a 24/48 VDC vehicle! The
device model is identified on the device type plate, a warning
sticker is affixed to the unit and on the external connector strip.
• Some forklifts have a chassis that is connected to DC. Therefore,
the 8580/8590 chassis is also connected to DC. However, if you
use peripheral devices that supply DC- to the 8580/8590 via an
interconnector (such as a DC- serial port), this will cause a short
circuit. This will inevitably lead to malfunctions or even a total
system failure.
• In DC-powered devices, always attach ring tongues on the
supply voltage cable to the ground bolt situated on the
connector bay.
• Make sure that the 8580/8590 connecting cable is attached as
close to the battery as possible. Connecting the vehicle-mount to
large electrical loads, such as converters for the forklift motor
may result in random restarts, malfunctions and/or irreparable
damage to the device.
• If you want to connect devices fed by other power sources to the
8580/8590, such as certain PS/2-Wedges, printers and so on, be
sure to power up the peripheral devices at the same time or after
the vehicle-mount. Otherwise, you may encounter start-up prob-
lems, malfunctions or even irreparable damage to the device.
