Before starting operation
in hazardous locations
Connect the earth continuity conductors
(earth wires) to the designated screw
on the explosion-proof motor and pump.
If the connection between motor and
pump already provides a conductive
path, one of the earth continuity
conductors may be deleted.
Remove paint and dirt from all connection points of earth continuity conductors and

containers to the electrically conductive base ground to ensure good conductivity.
The use of the commutator motor in combination with the pump requires
a complete and definite equipotential bonding. An equipotential bonding
consists in an electrically conductive connection between the motor and
the pump according to EN 50 014:1994-03 Paragraph 15 and DIN VDE
0165:1991-02 Paragraph 5.3.3.
The pump has to be arranged in a way that no friction and impinge
sparks form and that the operating conditions ensure safe operation.

Connection to the mains via an
explosion-proof plug device or
an explosion-proof cable
terminal box only.
Eelectrically conductive hose
(see TRbF 131 part 2)
completely mounted with
swaged hose fittings to ensure
a conductive path for the pump,
hose and fittings.
