OBU Manual
3 Installing the OBU
The OBU is designed for a voltage range of 8 V – 32 V DC and must therefore be used inside
this voltage range. If your on-board network can generate higher voltages (e.g. jump-starting
from an external power source or from additional stronger power generators in the vehicle),
the OBU must be disconnected from the on-board network for the duration of the over-
voltage.
The OBU can be installed in two ways:
1. Permanent / Fixed installation
2. Flexible installation
The status of the power supply is visible on the display:
Power supply via connection to the vehicle electric system.
Power supply via rechargeable battery. Please, consider the battery loading status during driving.
Permanent installation
The OBU is connected permanently to the vehicle electrical system.

Installation in an ADR vehicle is permitted only for fixed installation and must be performed by
authorized staff. If you wish to install the device into an ADR vehicle contact your Customer
Service.
The fixed installation of the OBU must be relied to the provided circuit diagram. Use the respective fuses.
