7.6.1. Essential information for vehicle applications (e.g. forklift)
− Observe the manufacturer’s instructions about the installation of peripheral devices.
− This is particularly important when welding or drilling supporting parts.
− Observe correct voltage ranges.
− Ensure that power supply cables are fused correctly.
− Make sure that the power supply cables are run without kinks and are protected
(securely protected against crushing and abrading).
− Read the labeling on the cable and connect the power supply cable with the correct
polarity.
− Cut the supply cable to the minimum length. This avoids tangled cables and
improves the quality of the power supply.
− Be sure that the connection of the power supply cables is as direct as possible to the
battery and not to power supply cables with a great deal of interference (e.g. the
motor power supply) or otherwise affected by consumers.
− Connect the power supply cable to a suitable place. Ensure that the connecting
cable has an adequate cross section and ampacity at the connection point.
− Observe the vehicle manufacturer’s instructions for connecting additional loads, for
instance, in conjunction with an emergency shut-off switch.
7.6.2. Electrical installation
Pay special attention to the various electrical potentials when installing the unit on
vehicles.
On the DLT-V83, the logic ground and the shield ground are firmly connected to each
other. The “logic ground” is the earth line (GND) for all of the internal electrical
components, such as the display and the CPU.
All cable shields and the housing are connected with the shield ground.
− Some forklifts have a chassis that is connected to DC+. Therefore, the DLT-V83
chassis is also connected to DC+. If peripheral devices supply DC− to the shield
connection of the DLT-V83 by a connection plug, for example over a serial
connection, this will cause a short-circuit and malfunctions or power failures will be
unavoidable.
− In DC-powered devices, always attach ring tongues on the supply voltage cable to
the provided ground bolt situated on the connector panel (see Fig. 7.2: Position of
the ground bolt).
