For use in a potentially explosive atmos-
phere,all parts of the equipment must satisfy
the requirements for the zone in which they
are used.
Note that it may be necessary to provide
equipotential bonding between the equip-
ment and the truck. The safe operation of the
vacuum pump in a potentially explosive at-
mosphere requires that all safety instructions
in our operating instructions and comple-
mentary instructions are strictly observed.
