Tightening torque
For the terminals X1 and X11 a tightening torque of:
0.4 Nm up to 0.5 Nm is valid
and for the terminals X2, X3, X4, X5, X6, X7, X8 and X9 a tightening torque of:
0.5 Nm bis 0.6 Nm is valid.
The stipulated tightening torques of the connection terminals must be
observed and applied. Again, they must be checked and possibly
adjusted before commissioning !
