CAUTION!
Danger of injury to personnel and material damage
Disregarding the technical data when installing can
lead to personal injuries or damage to property.
– Refer to the Technical Data - see the "Evolution
Data Sheet" chapter and the operating instructions
for the other components.
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.
– Only use motor protection switches, mains
switches and fuses permitted for use in areas at
risk from explosion in line with the manufacturer's
information, as electrical components in areas at
risk from explosion.
– Electrically wire all electrical units cleanly and per‐
manently to an electrically clean earthing point, -
e.g. with an earthing bar on your system.
– Electrically wire the earthing point on the pump
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!
ATEX pumps in areas at risk from explosion
Static electricity can cause ignition sparks.
– Consider potential equalisation before you
approach any pump equipment that could be at a
different electrical potential (such as pipes or tools)
WARNING!
Danger of fire with flammable feed chemicals
– The ATEX diaphragm rupture sensor and a dis‐
charge-side flow control must both stop the pump
as soon as a diaphragm rupture or no flow is
detected.
