not apply for the cable and transducer combination when connection is with
four‐wire configuration, the cable percentage must be added.

4.3 Shortening the cable

If the transducer is connected to an amplifier with a six‐wire configuration, the
transducer cable can be shortened as required, without adversely affecting
the measurement accuracy.

4.4 Cable extension

Only use shielded, low‐capacitance measurement cables for extension.
Ensure that connection is perfect, with a low contact resistance.
The cable of a six‐wire transducer can be extended with a cable of the same
type.

4.5 Parallel connection (option)

Only load cells with an aligned output (nominal (rated) sensitivity and output
resistance) are suitable for parallel connection. Type PW15B load cells are
available with this option.

4.6 EMC protection

Important
The load cells with shielded, round cables are EMC‐tested in accordance with
EC directives and identified by CE certification. However, you must connect
the shield of the connection cable on the shielding electronics enclosure in
order to achieve EMC protection for the measuring chain.
Electrical and magnetic fields often induce interference voltages in the meas­
uring circuit. Therefore:
 Use shielded, low‐capacitance measurement cables only (HBM cables
fulfill both conditions).
 Do not route the measurement cables parallel to power lines and control
circuits. If this is not possible, protect the measurement cable with e. g. steel
conduit.
