5.4 Electrical connection
To prevent interferences from coupling into the system, observe the following
information:
■
A shielded, low-capacitance measuring cable is attached to the force transducer.
■
A cable amplifier can be fitted optionally.
■
Ground the shield of the measuring cable.
■
Avoid stray fields of transformers, motors and contactors.
■
When using extensions, only shielded and low-capacitance cables should be used.
The permitted maximum and minimum lengths of cable are defined in ISO 11898-2.
Care should be taken also to ensure a high-quality connection even after the shiel-
ding.
■
Do not install measuring cables in parallel to 3-phase-current cables and control
cables.
■
Transducers, amplifiers and processing or display units must not be grounded sever-
al times.
The pin assignment of the cable and the cable amplifier (fitted optionally) can be
found on the product label.
