Assembling
5.3 Installing the machine
Procedure
The machine axis must be horizontal when it is lifted and the flange must be parallel to the
mating flange, so as to avoid seizing and stressing. Otherwise damage to the centering will
result.
1. Grease the centering flange with assembly paste to make the process easier.
2. Screw three studs into tapped holes spaced about 120° apart around the driven machine
3. Position the machine so that its axis is aligned with that of the driven machine, but not yet
4. If necessary, rotate the machine into the right position so that the clearance holes in the
5. Move the machine fully up against the mating flange so that it is fully in contact.
6. Fix the machine using the flange fixing bolts, finishing by replacing the studs.

Mounting the machine
Secure mounting of different motor variants
● For secure motor mounting, use fastening screws with the required property class per ISO
● On motors with an upwardly oriented shaft extension, make sure that no water enters the
● Machines that are attached to the wall by their mounting feet because of their type must
● Install motors with a belt output on clamping bars. This provides a simple way of ensuring
Alignment accuracy
The coaxial characteristic of the shafts of electrical machines and driven machine may not
exceed 0.05 mm in diameter.
