NOTICE!
Gear unit damage through overheating
• For geared motors, check that the cooling air from the motor fan can circulate around the gear unit
without obstruction.

The eye bolts which are screwed into the gear unit must be used for installing the gear unit. No
additional loads must be attached to the gear unit. If geared motors have an additional eye bolt
attached to the motor, this must also be used. Avoid pulling on the eye bolts at an angle. Observe the
safety information (please see chapter 1 "Safety information").
The base and/or flange to which the gear unit is fitted should be vibration-free, torsionally rigid and flat.
The flatness of the bolting surface on the base or flange must comply with DIN ISO 2768-2 tolerance
class K. All contamination of the bolting surfaces of gear unit and base or flange must be thoroughly
removed.
The gear housing must always be earthed. With geared motors, earthing via the motor connection
must be ensured.
The gear unit must be precisely aligned with the drive shaft of the machine in order to prevent
additional forces from being imposed on the gear unit due to distortion.
Welding of the gear unit is prohibited. The gear unit must not be used as the earth connection for
welding work, as this may cause damage to the bearings and gear wheels.
The gear unit must be installed in the correct orientation (please see chapter 7.1 "Versions and
maintenance").
All gear unit feet or all flange bolts on each side must be used. Bolts must have a minimum quality of
10.9. The bolts must be tightened to the correct torques (please see chapter 7.4 "Screw tightening
torques"). Tension-free bolting must be ensured, especially with foot and flange-mounted gear units.
Oil checking and oil drain screws must be accessible.
Information
Gear units with option XZ or XF
The foot mount is used to install and fasten the gear unit. It is designed to absorb the reaction forces
from the torque, permissible radial or axial forces and weight.
B5- or B14- flanges are not designed for mounting the gear unit and absorbing reaction forces. For
this, use the foot mount or contact Getriebebau NORD for investigation of the particular case.
