To prevent mechanical damage
,
all cables laid under ground must be properly
installed in underground electrical conduit specifically designed for this purpose,
cables must not be installed directly in the ground or in
concrete. (see fig. 4).
The pump must be earthed by connecting the earth (green) wire. Verify the
grounding continuity by checking that the grounding wire (green, labelled
as “E”) is electrically conductive with the bolt on the motor (paint to be stripped).
Ensure all electrical cables are securely supported and that there is no loose cable
which could be sucked into the pump inlet.
After installing the pump, secure the lifting chain or wire rope to a wall or other
rigid surface, outside of the pit, to prevent submerged in wastewater.
