The mounting holes and clearances correspond to the general toler-
ance according to ISO 2768-m.
Before attaching the motor to the machine, it must be aligned so
that the center line of the motor shaft is aligned with the center line
of the connecting shaft.
The following procedure is recommended for foot mounting of the motors:
1. In the case of MS2N13 forced ventilation: Dismount the lower lateral air
baffles to have free access to the mounting holes.
2. Align the motor such that the center line of the motor shaft is flush with
the center line of the connection shaft of the machine. To align the motor,
use sheet steel strips as a base.
3. Connect the motor firmly to the machine (for tightening torques, see tab.
6-1 "Mounting screws tightening torque (foot mounting)" on page 48).
4. In the case of MS2N13 forced ventilation: Reattach the air baffles to the
motor.

Radial forces may only be effective in a direction perpendicular to the mounting
surface (± 15°) if foot assembly is selected. The transmission of forces in other
effective directions is not allowed.
