7.2 Installation, Electrical

WARNING!
ATEX pump in area 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 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, with the
supply of individual components, with the operator's
explosion protection document.
– Only motor protection switches, mains switches and
fuses permitted for use in areas at risk from explosion in
line with the manufacturer's information may be used as
electrical components in areas at risk from explosion.
– Electrically connect the entire supplied installation
according to the earthing plan of the pump documenta‐
tion cleanly and permanently to an electrically clean
earthing point, e.g. with an earthing bar of your system.
– Note the enclosed documentation for the individual elec‐
trical components.
– Please note the relevant national regulations during
installation!
WARNING!
Danger of electric shock
Unprofessional installation may lead to electric shocks.
– Cable end sleeves must be crimped onto all cut-to-
length cable conductors.
– 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 ancillaries
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 management of the
system and inform personnel of the isolating option.
WARNING!
Danger of electric shock
The motor of this pump is equipped with a protective earth
conductor, to reduce the risk arising from an electric shock.
– Connect the PE conductor to "earth" with a clean and
permanent electrical connection.
