Connecting the cable
Requirement
You require a screwdriver with a maximum blade width of 3.5 mm.
Procedure
1. In EMC cable glands, lay the cable shielding over a large area.
Figure 6-6
2. With plastic cable glands, place the corresponding wire of the SIWAREX load cell on the
shield terminal.
3. Strip at least 6 mm of insulation from the load cell cable.
Figure 6-7
4. Insert the stripped load cell cable into the square opening of the screw terminal as far as it
will go.
5. Tighten the screws with the specified tightening torque.
Result
The tightened screw firmly holds the stripped wire and establishes the contact.

Shield connection
Make sure you observe the correct design of the shield support for the shielded cables. It is the
only way to ensure immunity of the system.
A cable is shielded to attenuate the effects of magnetic, electrical and electromagnetic
interference on the cable. Interference currents on cable shielding are diverted to ground by
conductive isolation rails. To avoid interference as a result of these currents, it is imperative to
provide a low-impedance connection to the ground.
Only use cables equipped with a shielding braid. Shielding density must be at least 80%.
