Preliminary work
Motor shaft ends must be thoroughly cleaned of anti-corrosion agents, contamination or
similar (use a commercially available solvent). Do not allow the solvent to penetrate the
bearings or shaft seals – this could damage the material.
Motors with rein-
forced bearing
NOTE
Do observe the safety notes in chapter 2 (see page 7) for when installing the unit!
1) Note that the temperature range of the gear unit may also be restricted (see gear unit operating instruc-
tions).
STOP
The mounting position for installation must correspond to the specifications on the
