4.2.2 Operation with DC Voltage
The TriBox3 can also be integrated into battery-powered measuring stations. For these applications, the Tri -
Box3 can be operated with 12–24 V (± 5%) DC voltage. Instead of the connection cable with Schuko plug, the
12–24 V DC can be directly connected to the TriBox3. When operating on 12–24 V DC power, the Schuko
plug can be removed, but this is not absolutely necessary. Be sure that the DC power source can provide the
necessary maximum power and has an output with low impedance. To operate the TriBox3 with DC power,
follow these steps:
To open the box and to attach a suitable cable to the TriBox3, please proceed as follows:
1. Carefully remove the aluminium panels on both sides of the device.
2. Remove the four screws on the edge of the TriBox3 with a Phillips screwdriver.

Before making any changes to the power line or the plug, it is essential to
make sure that the power is disconnected and cannot be reconnected or
switched on.
DANGER
3. After removing the four screws, carefully open the cover of the housing upwards. The housing cover
must be able to be opened without resistance and without the use of force, otherwise there is a risk of
damaging the wires in the device.
4. Connect the DC power cable to the plug labelled CON2 in the illustration. The following table describes
the contact assignment.
