INSTALLATION
The installation should be done by a person with knowledge of automotive installations.
1. The D250T & SMARTPASS 120T unit(s) should not be directly exposed to fuel, oil or dirt. They
should be installed on a flat surface to ensure they can be firmly secured. If you are fitting both units
together attach the accompanying connector plate (see Figure 3) before fitting them into the vehicle.
2. Secure the unit(s) with M4 or ST4.2 screws at each corner (see Figure 1).
3. Before connecting the cables, ensure that the negative terminal post on both the starter and service
battery is not connected.
4. Connect the cables to the unit connections by securing the M8
screws with the required tightening torque. (see Figure 2).
Use an Allen key - tightening by hand without a tool is not
enough. The cables connected to M8 terminals must be
equipped with ring terminals. Max thickness of connected ring
terminal(s) is 6mm (see figure 5).
5. Use tape (see Figure 4) to secure the temperature sensor
to a clean flat surface above the service battery. Position the
sensor as close to the positive terminal post as
possible.
6. Connect the battery negative terminal post.
