WARNING!
ATEX pumps in areas at risk from explosion
– Only connect potential-free as well as non-isolating
low voltage switch accessories, such as diaphragm
rupture indicators, stroke rate instruments etc., to an
intrinsically safe power circuit in areas at risk from
explosion.
– If several electrical components are connected
together, the safety of the entire connected system
has to be tested and confirmed in terms of its safety.
This can either be in the form of a Declaration of
Conformity from the supplier (ProMinent) for the
entire unit or, if individual components are supplied,
in the form of the operator's explosion protection
document.
– Only motor protection switches, mains switches and
fuses permitted for use in areas at risk of explosion
in line with the manufacturer's information may be
used as electrical components in areas at risk of
explosion.
– Electrically connect the electrical units listed on the
earthing diagram in the appendix, cleanly and per‐
manently, to an electrically clean earthing point, -
e.g. with an earthing bar on your system.
– Electrically connect the electrical units fitted with a
potential equalisation cable to each other, cleanly
and permanently, to an electrically clean potential
equalisation point - e.g. with a potential equalisation
bar on your system.
– Note the enclosed documentation for the individual
electrical components.
– Please note the relevant national regulations during
installation!
WARNING!
Danger of electric shock
Unprofessional installation may lead to electric shocks.
– Crimp cable end sleeves onto all shortened cable
cores.
– Only technically trained personnel are authorised to
undertake the electrical installation of the device.
WARNING!
Danger of electric shock
In the event of an electrical accident, it must be possible
to quickly disconnect the pump, and any electrical ancil‐
laries which may possibly be present, from the mains.
– Install an emergency cut-off switch in the mains
supply line to the pump and any electrical ancillaries
which may be present or
– Integrate the pump and electrical ancillaries which
may be present in the emergency cut-off manage‐
ment of the system and inform personnel of the iso‐
lating option.
