Before start-up of the coupling, inspect the tightening of the setscrews in the coupling flanges, the alignment and
the distance dimension E or E
1
and adjust, if necessary, and also inspect all screw connections for the tightening
torques specified, dependent on the type of coupling.
The setscrews to fasten the flange hubs as well as all screw connections must be secured
against working loose additionally, e. g. conglutinating with Loctite (average strength).
Finally the coupling protection against accidental contact must be fitted. It is required in accordance with
DIN EN ISO 12100 (Safety of Machinery) and must protect against
access with the little finger
falling down of solid foreign objects.
The cover may provide for openings intended for necessary heat dissipation. These openings have to comply with
DIN EN ISO 13857.
The cover must be electrically conductive and included in the equipotential bonding. Bellhousings (magnesium
share below 7.5 %) made of aluminium and damping rings (NBR) can be used as connecting element between
pump and electric motor. The cover may only be taken off with standstill of the unit.
