Siemens AG Operating Instructions 1.03 1RQ671...-Z
● If a higher degree of protection is required, it may be necessary to install appropriate
filters and arrange the intake and/or outlet openings specially as needed.
● All parts must be mounted free from strain.
● In the case of motors with a built-on separately driven fan unit and with air-to-air or air-to-
water coolers the relevant operating instructions must be observed.
Loads on shaft extension
The permissible values for longitudinal and cantilever forces must be requested if necessary.
[ID 1005.01]
5.3 Aligning
Requirements
Detailed specialist knowledge of the following measures is required in order to correctly align
and securely fit the equipment.
● Preparing the foundation
● Selecting and mounting the coupling
● Measuring the concentricity and axial eccentricity tolerances
● Positioning
If you are not familiar with the prescribed measures and procedures, then you can make use
of the services offered by the local Siemens Service Center (Page 69).
Vertical and horizontal alignment
To compensate for the radial offset on the coupling, the electrical machine and the driven
load must be aligned with each other.
● Place shims under the motor feet to position it vertically and to prevent stress/distortion.
The number of shims should be kept as low as possible, so use as few thicker shims as
possible, instead of several thinner shims.
● For horizontal positioning, push the motor sideways on the foundation Pay attention to
maintaining the axial position.
● When positioning the motor, ensure that a uniform axial gap is maintained around the
coupling.
Alignment accuracy
A diameter of 0.05 mm is required to satisfy the coaxial requirements for the shafts of the
motor and the driven machine. [ID 208.02]
