Check all functions.
Use only clean water to clean the components. Note the Ingress Protection (IP) ratings (IEC 60529).

Electrical connection:

Note cable cross-sectional area!
Reducing the cable cross-sectional area leads to higher current density, which can cause the cable cross-sectional area in question to heat up!
When installing electrical cables, use the provided cable ducts and harnesses; however, do not run cables parallel to ignition cables or to cables that lead to large electricity consumers.
Fasten cables with cable ties or adhesive tape. Do not run cables over moving parts. Do not attach cables to the steering column!
Ensure that cables are not subject to tensile, compressive or shearing forces.
If cables are run through drill holes, protect them using rubber sleeves or the like.
Use only one cable stripper to strip the cable. Adjust the stripper so that stranded wires are not damaged or separated.
Use only a soft soldering process or commercially available crimp connector to solder new cable connections!
Make crimp connections with cable crimping pliers only. Follow the safety instructions of the tool manufacturer.
Insulate exposed stranded wires to prevent short circuits.
Caution: Risk of short circuit if junctions are faulty or cables are damaged.
Short circuits in the vehicle network can cause fires, battery explosions and damages to other electronic systems. Consequently, all power supply cable connections must be provided with weldable connectors and be sufficiently insulated.
Ensure ground connections are sound.
Faulty connections can cause short circuits. Only connect cables according to the electrical wiring diagram.
If operating the instrument on power supply units, note that the power supply unit must be stabilized and it must comply with the following standard: DIN EN 61000, Parts 6-1 to 6-4.
