7.5.1. Electrical installation
Pay special attention to the various
electrical potentials when installing the
unit on a vehicle (such as a forklift).
n the DLoG MTC 6, the logic ground and
the shield ground are firmly linked.
The “logic ground” is the earth line (GND)
for all of the internal electrical
components, such as the isplay and the
CPU.
The cable shielding and the housing are
connected to the “shield ground”.

Caution:
Property
damage
Pay attention to the following warnings!
•
Some forklifts have a chassis that is connected to DC
+
. Therefore, the
DLoG MTC 6 chassis is also connected to DC
+
. However, if you use peripheral
devices that supply DC– to the DLoG MTC 6 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.
