4.3 Motor installation notes
CAUTION
Sharp edges due to open keyway.
Cuts.
• Insert the key into the keyway.
• Pull a protective tubing over the shaft.
NOTICE
Improper assembly may damage the drive and corresponding components.
The drive system might be damaged.
• Observe the following information.
• Thoroughly clean the motor shaft ends and flange surfaces and make sure that
they are free from anti-corrosion agent, dirt or the like (use commercially available
solvent). Do not allow the solvent to come in contact with the bearings or sealing
rings.
• Only install the gearmotor in the specified mounting position on a level, vibration-
free and torsionally rigid support structure.
• The mounting position for installation must correspond with the specifications on
the nameplate.
• 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.
• 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.
• Use an appropriate cover, e.g. option /C "Canopy", to prevent objects or fluids en-
tering motors in vertical mounting positions (M4/V1).
• Balance components for subsequent mounting on the shaft with a half key (motor
shafts are balanced with a half key).
• Existing condensation drain holes are sealed with closing plugs. If contaminated,
the condensation drain holes must be checked for proper functioning on a regular
basis and cleaned if required.
