Tightening torques for the
line, motor and PE termi-
nals (M12): 50 Nm
The cable entry protection
for the line connection (
must be broken out corre-
sponding to the diameter of
the cable to be introduced.
The cable entry protection
for the motor connection is
described in the following
section.
After connection, the co-
vers of the line and motor
terminals must be rein-
stalled (tightening torque:
6 Nm).
In order to ensure a uni-
form current distribution,
first connect the motor ca-
ble to the upper connection

Only use the lower connec-
tion points if the upper con-
nection points have been
