−
The other end of the yellow-green power supply cable must be connected to the vehicle’s
chassis.
−
Connect the power supply cable of the DLT-V83 as close to the battery as possible.
Connecting the DLT-V83 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 DLT-V83 (e.g. printers), be
sure to power up the peripheral devices at the same time or after the DLT-V83; otherwise,
you may encounter start-up problems, malfunctions or even irreparable damage to the device.
7.6.3. Electrically isolated installation of DC devices
DANGER
Risk of accident on vehicles due to unexpected vehicle emergency stop because of
electro conductive connection of the DLT-V83 to the vehicle chassis.
Due to a variety of technical properties of forklifts and forklift trucks, it can be necessary to
electrically isolate DLT-V83 from the chassis of the vehicle to prevent malfunctions. The
necessity of this must be studied on a case-by-case basis, however, it is recommended for
vehicles with potential-free chassis.
For example, using rubber buffers ensures that the terminal has no electrically conducting
connection to the vehicle chassis.
If peripheral equipment (such as scanners, printers, scales or similar), which has its own power
supply unit is used, you must ensure that the power supply units of these peripherals are
galvanically separated from the supply of the vehicle.
Moreover, the peripheral equipment and its cabling must be attached electrically isolated.
If external antennas are being used, you must ensure that the antennas are isolated at the
mounting point on the vehicle chassis.
