4.1. Mechanical installation

4.1.1. Preparation and lifting

Remove the anti-corrosion coating.
Always use the holes for the lifting eye bolts when lifting the motor, see Figure 5 and Figure 6.

4.1.2. Installation of coupling

To ensure low noise and vibration levels, the alignment between the motor shaft and the mating coupling
must be accurate. The higher the motor operating speed the higher accuracy is needed. The figure below
illustrates the concentricity and perpendicular demands for the mating coupling.
Figure 7.
The values for X and Y depending on motor operating speed could be found in Table 3.

Table 3.
For side support mounting, see Figure 1. Some type of flexible coupling shall be used and the geometrical
tolerance demands can differ between type and supplier. See manual from the coupling supplier.
For dimensions involving the motor's shaft, flange and side support, see the outline drawing. The
product code is visible on the rating plate, see Figure 2.
