Danger of injury to personnel and material damage
n
Disregarding the technical data during installation can lead to personal
injury or damage to property.
n
Observe the technical data - refer to the Chapter "Technical data" and,
where applicable, the operating instructions for the accessories.
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.
ATEX pumps in areas at risk from explosion
n
Electrically connect the electrical assemblies listed on the earthing
diagram in the appendix, cleanly and permanently, to an electrically
clean earthing point, e.g. with an earthing bar on your system.
n
Electrically connect the assemblies 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.
n
Note the documentation supplied for the individual electrical compo‐
nents.
Risk of fire with flammable feed chemicals
n
An ATEX diaphragm rupture sensor or, possibly, a flow control fitted
on the discharge side, must stop the pump safely and as quickly as
possible as soon as there is a diaphragm rupture or, for instance, in
the event that there is no flow.
Danger of electric shock
n
Improper installation can lead to electric shocks.
n
Crimp cable end sleeves onto all stripped cable cores.
n
Make sure that only technically trained personnel are authorised to
undertake the electrical installation of the unit.
WARNING!
Danger of electric shock
–
There can still be dangerous voltage present for 3
minutes in the interior of motor designs with integral
frequency converter.
–
Only open the drain screw 3 minutes after the mains
voltage has been switched off.
Never change the “Motor voltage” and “Cycle frequency” parameters with
motor designs with integral frequency converter.
The parameters on delivery from ProMinent do not correspond to the
motor manufacturer’s factory settings.
If other parameters are to be changed, then we recommend speaking to
ProMinent head office in Heidelberg.
