Mechanical installation
Risk of accident on vehicles due to unexpected vehicle emergency stop because of
electro-conductive connection of the DLT-V72 to the vehicle chassis.
Due to a variety of technical properties of forklifts and forklift trucks, it can be necessary to
electrically isolate DLT-V72 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.
NOTICE: Physical damage
Installation environment without cooling air can overheat/damage the DLT-V72.
The DLT-V72 employs a passive cooling concept whereby the waste heat generated inside the
device is emitted from the surface of the housing.
For this system to function properly, sufficient fresh air circulation is required.
If there is no access to fresh cooling air, it may result in overheating and severe damage to the
device.
Never install the system in a closed environment where the cooling air is unable to dissipate
accumulated heat to the outside.
The maximum permissible ambient temperature for the entire system needs to be taken into
account for the specific application area.
