CAUTION
Impacts and shocks applied to the shaft end will damage the rotary
encoder and ball bearings!
Drive elements such as pulleys, clutch disks, toothed wheels etc.
may only be assembled or removed by continuously heating up
the drive elements or with a suitable installation or removal tool.
Use the thread in the shaft end.
At least half of motors with an oil-tight flange on the output side (oil-
running tight, designs 100, 101) must be submerged in oil. Due to the
high friction, they must never be started dry.
For dry operation, the rotary shaft seal must be removed, however, it
cannot be reinstalled afterwards.
CAUTION
Loss of data!
Interventions in the motor may delete the data of the electronic rat-
ing plate.
Do not dismantle servo motors. Installation work in excess of the
adjustment of the outgoing cable direction must be performed in
the manufacturer's workshop.
The outgoing direction of all plug-in systems can be changed by releas-
ing the angle flange box.
Do not turn the angle flange box by more than 180_ in order to avoid
damaging the connection leads.
CAUTION
Moisture inside the motor.
When tightening the angle flange box, please make sure that the
O-ring is properly seated in the groove of the angle flange box.
Protection standard IP 67 is achieved for the plug-in system only
if the admissible external lead diameters are maintained and the
mating connectors are screwed down to their stop.
