Mounting and installation
Installing the junction box
2. Insert the cable to the end of the coat. There should only be cable cores inside the junction box.
The cable coating must end at the junction box casing. This is the only way to ensure that you
have enough space in the junction box to be able to guide all of the cable cores to the terminals.
3. Remove the cable coating of the cable cores ca. 1 cm from the end of the cable core.
4. CAUTION! Pay attention to the proper polarity of the cable cores and the terminals.
5. Connect the cable cores to the terminals.
To do so, use the information on the lid of the junction box, on the relay circuit board and in the
pin-out diagram.
6. With screw terminals, use wire end sleeves. Wire end sleeves may not be used with spring-
loaded terminal blocks.
7. Close the screw connections of the junction box.
After screwing them shut, the glands should be sealed.
8. Close unused openings in the casing of the junction box with blind caps.
Inserting the cable core into a terminal
Each terminal consists of two openings:
▪ The upper opening of the terminal opens the lower opening.
▪ The bottom opening of the terminal serves to insert and clamp one cable core.
You have prepared a small flat screwdriver that fits the upper opening of the terminal. You only
need this screwdriver if there are no wire end sleeves on the cable cores.
You have cut the cable to the proper length and have exposed the cable cores according to the
instructions, or you have a finished cable from Müller Elektronik.
The tractor engine is switched off.
The junction box is not powered.
There is no voltage on the components to be connected.
1. Find the proper connectors for the cable cores to be connected.
To do so, use the information on the lid of the junction box, on the relay circuit board and in the
pin-out diagram.
2. Insert the cable core into the opening in the lower part of the terminal. If you are not using wire
end sleeves, you first have to use the screwdriver.
⇨ The cable core will be held by the terminal.
⇨ You have clamped the cable core.
Connecting the junction box to the job computer
1. Connect the AMP connector of the junction box onto the proper job computer.
