5.2 - INSTALLING AN IEC-STANDARD FLANGED MOTOR
Further to all the precautions indicated above, when installing a IEC-flange mount electric motor the following
precautions must also be observed:
•
Do not force the coupling and do not use inappropriate tools during assembly. Take care not to damage
the flat and/or cylindrical coupling surfaces.
•
Do not force the shaft with large radial and/or thrust loads.
•
To facilitate assembly, use a lubricating synthetic oil paste such as Klüberpaste 46 MR 401 or equivalent
product with similar properties and application range.
•
Tighten down all motor/gear unit mounting bolts to their prescribed torque. For the tightening torques, refer
to table (A0).
When the gear unit is mounted to an IEC electric motor, proceed as follows:
•
Apply a layer of sealant (Loctite 510 or equivalent product with similar properties and applica
-
tion range) to the motor/gear unit mounting flanges, spigot and frontal coupling surfaces as
shown in diagram (S1).

•
After mounting the motor, apply a layer of sealant (Loctite 5366 or equivalent product with simi
-
lar properties and application range) around the edges of the flanges so as to close any gaps
between their surfaces.
•
If the gearbox is of the flanged type, the User must take similar precautions to prevent dust de
-
posits forming in the gaps between the flanges or in the vicinity of the couplings.
1 - Apply “Loctite 510” to both the flange
surface and spigot.
2 - Apply “Klüberpaste 46MR401” to the
input shaft bore and motor shaft.
3 - Use “Loctite 5366” to seal the area
of contact between the gear unit and
motor, taking care to fill in any gaps
between the two flanges (e.g. disas
-
sembly slots).
