5.1

Cabling

Electrical and magnetic fields often induce interference
voltages in the measurement circuit.
S Use shielded, low‐capacitance measurement cables
only (HBM cables fulfill these conditions),
S Do not route the measurement cables parallel to
power lines and control circuits. If this is not possible,
protect the measurement cable with steel conduit for
example.
S Avoid stray fields from transformers, motors and con­
tact switches.
S For C2A/.../Exd please note, when mounting; the fixed
connection lead must have a mechanical securing.
5.2

Connection technology

Load cells with a strain gage measuring system can be
connected to:
S carrier‐frequency measuring amplifiers, or
S DC measuring amplifiers suitable for strain gage mea­
suring systems.
The load cells are connected using the six‐wire circuit.
The wiring assignment is shown in the following diagram.
