4. If the coupling half contains a threaded pin, the coupling must be secured axially on the

shaft. The threaded pin must be coated prior to use with a securing lubricant e.g. Loctite
242, Loxeal 54-03 and tightened to the correct torque. (See Chapter 6.3 for torque values)

5. The flange surfaces of motor and adapter must be completely coated with surface sealant

e.g. Loctite 574 or Loxeal 58-14 prior to mounting the motor, so that the flange seals after
mounting. (only necessary for category 2D gear units – see ATEX labelling on the last line of
the gear unit rating plate) Sealing of the flange surfaces is also recommended for installation
outdoors or in damp environments.

6. Mount the motor to the adapter. Do not forget to fit the gear rim or the sleeve.

(See Figure 3-14)

7. Tighten the adapter bolts to the correct torque. (See Chapter 6.3 for torque values)
