7 Electrical connection
The following can be connected for measurement signal conditioning:
S
Carrier-frequency amplifiers
S
DC amplifiers
designed for strain gage measurement systems.
The load cells are delivered with a six-wire configuration. Optionally available
with different cable lengths.

Fig. 7.1 Pin Assignment
With this connector pin assignment, the output voltage at the measuring
amplifier is positive in the tensile direction when the transducer is loaded.
7.2 Connection in four-wire configuration
When transducers in a six-wire configuration are connected to amplifiers in a
four-wire configuration, the sense leads of the transducer must be connected
to the corresponding excitation voltage leads: Marking (+) with (+) and marking
(-) with (-),
see Fig. 7.1 . This measure also reduces the cable resistance of the
