6. Application in explosion hazard areas
6.1 Equipotential bonding and earthing
Before starting up the pump, an equipotential bonding
must be established between the pump, the container
to be emptied and the container to be filled.
The potential between the pump and the container to
be emptied is equalized by connecting the equipoten-
tial bonding cable (order no. 0204-994). Paint and dirt
should be removed from the connecting points in order
to improve the conductivity.
The conductive connection between the full and empty
containers must either be achieved by an equipotential
bonding cable or by means of a conductive substrate
(e.g. conductive gratings). Using the equipotential
bonding cable drum and container must be connected
with the earth potential. Using a grating the transition
between container and substrate must also be conduc-
tive.

6.2 Explosion protection regulations
A number of regulations have to be observed by the
operator for use of equipment in hazardous areas. The
following list renders an overview of the significant re-
gulations.
Within the EU are valid:
- DIRECTIVE 1999/92/EC on minimum requirements
for improving the safety and health protection of
workers potentially at risk from explosive atmos-
pheres
- EN 50014
Electrical appartus for potentially explosive atmos-
pheres - general requirements
- EN 60079-14 (IEC 60079-14)
Electrical appartus for potentially explosive atmos-
pheres - part 14 electrical installations in hazardous
areas (other than mines)
- EN 60079-10 (IEC 60079-10)
Electrical appartus for potentially explosive atmos-
pheres - part 10: classification of hazardous areas
- DIN EN 1127-1
Explosive atmospheres - explosion preventation
and protection - part 1: basic concepts and metho-
dology
- Directive 67/548/EEC (directive on substance)
National rules and regulations have to be observed.
