6.1.1 Flange assembly
Motor damage due to ingress of liquids!
NOTICE
Liquid which exists over a longer period on the shaft sealing ring of the output
shaft can ingress into the motor and cause damage.
Ensure that liquid cannot be present at the output shaft.
Do not mount any open gearboxes (gearboxes that are not hermetically
sealed).
For details on mounting holes, refer to the project planning manual Asyn‐
chronous Housing Motors MAD/MAF. Use all motor mounting holes to mount
the motor safely to the machine.
If coupling is direct, ensure that the support is plane and the orientation is
precise.
Avoid pinching or jamming the centering collar on the motor side.
Avoid damaging the receptacle fit on the plant side.
Use the following screws and washers for flange assembly.

6.1.2 Foot mounting
Before attaching the motors according to the foot assembly method, observe
the clearance from the center of the motor shaft to the bottom edge of the
foot specified in the particular motor dimension drawing. Compare this dimen‐
sion with the connection dimension on the machine side.
The mounting holes and clearances correspond to the general tol‐
erance according to DIN ISO 2768-1 (tolerance class 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. MAD130 ... 225: Dismount the lower lateral air baffles to have free ac‐
cess to the mounting holes.
2. Align the motor so that the center line of the motor shaft is aligned with
the center line of the machine connecting shaft. To align the motor, use
sheet steel strips as a base.
3. Connect the motor firmly to the machine.
