Assembly procedure to attach a standard motor to the IEC adapter (Option IEC/NEMA adapter)
1. Clean the motor shaft and flange surfaces of the motor and adapter and check for damage. The
mounting dimensions and tolerances of the motor must conform to DIN EN 50347 / NEMA MG1
Part 4.
2. Push the coupling sleeve onto the motor shaft so that the motor parallel key engages into the
groove in the sleeve on mounting.
3. Tighten the coupling hub on the motor shaft in accordance with the motor manufacturer’s
instructions until it touches the collar. With motor sizes 90, 160, 180 and 225, any spacer bushes
may need to be positioned between the coupling sleeve and the collar. With standard helical gear
units, dimension B between the coupling sleeve and the collar must be observed (see "Figure 19").
Certain NEMA adapters require adjustment of the coupling in accordance with the specifications
indicated on the adhesive plate.
4. If the coupling half contains a threaded pin, the coupling must be secured axially on the shaft. The
threaded pin must be coated with a securing lubricant, e. g. Loctite 242, Loxeal 54-03 prior to use
and tightened to the correct torque (please see chapter 7.4 "Screw tightening torques").

5. Sealing of the flange surfaces of the motor and the IEC adapter/ NEMA adapter is recommended if
the motor is installed outdoors or in a humid environment. Before the motor is installed, the flange
surfaces must be completely coated with surface sealant e.g. Loctite 574 or Loxeal 58-14 so that
the flange seals after mounting.

6. Mount the motor on the adapter. Do not forget to fit the ring gear or the gear sleeve (see Figure
unterhalb).
7. Tighten the adapter bolts to the correct torque (please see chapter 7.4 "Screw tightening torques").
