Before start-up of the coupling, inspect the tightening of the setscrews in the hubs, the alignment and the distance
dimension E and adjust, if necessary, and also inspect all screw connections for the tightening torques specified.
If used in potentially explosive atmospheres the setscrews to fasten the 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 directive 2014/34/EU 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.
