4.4 Setting up the drive unit
4.4.1 Notes
• Only install the drive unit on a level, low-vibration, and torsionally rigid support
structure.
• Observe the mounting position specified on the motor nameplate.
• Thoroughly remove any anti-corrosion agent from the shaft end. Use a commer-
cially available solvent. Do not allow the solvent to penetrate the bearings and
sealing rings as this could damage the material.
• Align the motor carefully to avoid placing any unacceptable strain on the motor
shafts. Observe the permitted overhung and axial loads specified in the respective
gearmotor catalog.
• Do not jolt or hammer the shaft end.
• Ensure that cooling air supply is unobstructed and that air discharged by other
units does not influence cooling.
• Balance components that were subsequently mounted to the shaft with a half key
(output shafts are balanced with a half key).
• Use suitable cable glands for the supply leads (use reducing adapters if neces-
sary).
• Seal the cable entry properly.
• Thoroughly clean the sealing surfaces of the cover before reassembly.
• If the corrosion protection coating is damaged, restore the coating.
• Check whether the degree of protection specified in the operating instructions and
on the nameplate is permitted in the ambient conditions on site.
• Observe the information of Directive VDI 2230-1 on determining the tightening
torques for mounting the drive unit to the application.
Changing the mounting position
Make sure to read the following information when you operate the drive unit in a
mounting position other than the one indicated in the order:
• Adjust the position of the breather valve, if necessary.
Also observe the information in the catalog "MOVIMOT
