7.5.3. Installing connecting cables
If possible, use the connecting cables supplied to connect the DLoG MPC 6 to the power
supply.
Make sure that the connecting cables are laid without kinks and are protected.
7.6. 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 DLoG MPC 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 hard drive and the CPU.
Cable shielding, the housing and the ground conductor (in AC-powered units) are
connected to the shield ground.
Carefully read the following warnings!
•
Never connect a 12 VDC device to a 24/48 VDC vehicle! The device model is
written on the device type plate, a warning sticker on the front of the unit and on the
external connector strip.
•
Some forklifts have a chassis that is connected to DC
+
. Therefore, the DLoG MPC
6 chassis is also connected to DC
+
. However, if you use peripheral devices that
supply DC– to the DLoG MPC 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 .
