15.2.3. Electrically isolated installation of DC devices
Risk of accident on vehicles due to unexpected vehicle emergency stop because of
electro conductive connection of the DLT-V4108 to the vehicle chassis.
Due to a variety of technical properties of forklifts and forklift trucks, it can be necessary to
electrically isolate DLT-V4108 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.
