WAR NING
Unprotected rotating coupling
Risk of injury by rotating shafts!
Always operate the pump set with a coupling guard.
If the customer specifically requests not to include a coupling guard in PUMPIRAN
,
s
delivery, then the operator must supply one!
Observe all relevant regulations for selecting a coupling guard.
DANG E R
Risk of ignition by frictional sparks
Explosion hazard !
Choose a coupling guard material that is non-sparking in the event of
mechanical contact (see DIN EN 13463-1).
DANG E R
Incorrect electrical installation
Explosion hazard!
For electrical installation, also observe the requirements of IEC 60079-14.
Always connect explosion-proof motors via a motor protection switch.
DANG E R
Work on the pump set by unqualified personnel
Danger of death from electric shock!
Always have the electrical connections installed by a trained electrician.
Observe regulations IEC 30364 (DIN VDE 0100) and, for explosion-proof pump
sets, IEC 60079 (DIN VDE 0165).

5.8 Electrical connection
The coupling guard and step guard, if any, have been removed.
1. Check the coupling alignment.
2. Unscrew the hexagon head bolts at the motor.
3. Insert shims underneath the motor feet until the difference in shaft centre height has been
compensated.
4. Re-tighten the hexagon head bolts.
5. Check that the coupling and shaft can easily be rotated by hand.
6. Re-install the coupling guard and step guard, if any.
7. Check the distance between coupling and coupling guard. The coupling guard must not
touch the coupling.
