11.2.3
Three knuckle eyes are provided for tensile force introduction:
− an upper knuckle eye for coupling M3 (Option A, 1−U1/5kg/ZGO)
− an upper knuckle eye for internal thread M5 (Option C, 1−U1/5kg/ZGU)
− a lower knuckle eye for internal thread M5 (all types, 1−U1/5kg/ZGU)
The upper knuckle eye is either mounted using the coupling from the list of
components supplied (see Fig. 4.5) or is screwed directly into the
load−bearing plate. Take care not to exert any forces on the load−bearing
plate that might damage the transducer.

Code A (centre−pin):
• Screw lower knuckle eye into the coupling; starting torque approx. 2 N⋅m.
• Remove the spring from the coupling
• Push the coupling onto the load−bearing centre pin and use the spring to
secure it in the groove provided. Brace against the load−bearing plate, not
against the housing.
