2. Remove the key from the motor shaft. Replace the key from the motor shaft with
the supplied key [484] (not AM63 and AM250).
3. Heat the coupling half [479] to approx. 80 – 100 °C and push the coupling half onto
the motor shaft. Position as follows:
•
IEC adapter AM63 – 225 until stop at motor shaft shoulder.
•
IEC adapter AM250 – 280 to distance "A". The values for the distance "A" are lis-
ted in the following table.
•
NEMA adapter to distance "A". The values for the distance "A" are listed in the fol-
lowing table.
4. Secure the key and coupling half using the set screw [481] on the motor shaft.
Refer to the following table for the required tightening torque "T
A
".
5. Check the position of the coupling half. The values for the distance "A" are listed in
the following table.
6. Seal the contact surfaces between the adapter and motor using a suitable sealing
compound.
7. Mount the motor on the adapter. Ensure that the coupling claws of the adapter
shaft are engaged in the plastic cam ring.

Permitted loads
NOTICE
Overloading of the gear unit due to excessive weight or excessive power rating of an
attached motor.
Gear unit failure
•
Note that the load data specified in the following table are not to be exceeded.
•
Make sure that the approved power rating (torque and speed) on the adapter is
observed according to the nameplate.
NOTICE
Danger due to static overdetermination when motors are additionally attached via a
foot plate.
Damage to property
•
A motor attached at the foot relieves the interface on the adapter, but you have to
make sure that the attached foot-mounted motor is attached to the customer’s
construction stress-free.
