Motor installation notes
Observe the following when setting up the motor:
CAUTION
Sharp edges due to open keyway.
Cuts.
•
Insert the key into the keyway.
•
Pull a protective tubing over the shaft.
•
Remove any anti-corrosion agent and dirt from motor shaft ends and flange sur-
faces. Use a commercially available solvent. Do not allow the solvent to come in
contact with the bearings or sealing rings.
•
The mounting position for installation must correspond with the specifications on
the nameplate.
•
Only install the gearmotor in the specified mounting position on a level, vibration-
free and torsionally rigid support structure.
•
Make sure the customer's counter-bearing is unobstructed and can move freely.
•
Align the motor and the driven machine carefully in order to prevent the output
shaft from being exposed to unacceptable strain. Observe the permitted overhung
and axial forces.
•
Do not jolt or hammer the shaft end.
•
Balance components for subsequent mounting on the shaft with a half key (motor
shafts are balanced with a half key).
•
Make sure that there is sufficient clearance around the motor to provide for ad-
equate cooling air supply, and that the motor does not draw in warm exhaust air
from other units. Observe the minimum distances specified in the chapter
4.3.1
