5.8 Coupling guard
The pump may only be operated with a coupling guard in accordance with the accident prevention regu-
lations.
WARNING:
The coupling guard used in an ATEX classified environment must be constructed from a spark
resistant material.
5.9 Final check
Check the alignment of the coupling again in accordance with
5.3 Alignment of pump - coupling motor on
.
It must be possible to easily turn the unit at the coupling by hand.
5.10 Electric connection
WARNING:
Only have the electric connection performed by a qualified electrician. Compare the available
mains voltage with the information on the type plate of the motor and select a suitable circuit.
It is urgently recommended to use motor protection facilities (motor protection switch).
In potentially explosive areas IEC 60079-14 must also be observed for the electrical installation.
It must be ensured that the pump is grounded. This can be achieved in the simplest case by using a
toothed-lock washer or a contact disc at the housing support if the substructure itself is grounded. Other-
wise, grounding must be ensured by other means, e.g. cable bridges.
Units supplied by Goulds (pump and base plates) are to be grounded using suitable devices on the base
plate.
