RISK of fatal injury due to explosion!
Pumps without Ex labelling may not be used
in potentially explosive areas! There is a risk
of fatal injury due to explosion! Observe the
following when using the pump in explosion
hazard areas:
• The pump must be approved for use in poten-
tially explosive areas!
• The power supply cable must be connected
outside the potentially explosive area, or
inside a housing with ignition protection con-
forming to DIN EN 60079-0!
• Switchgears must be installed outside the
potentially explosive area, or inside a hous-
ing with ignition protection conforming to
DIN EN 60079-0! Furthermore, these must be
configured for operation of pumps with explo-
sion approval.
DANGER of explosion!
The housing of the hydraulics must be fully
flooded (completely filled with the fluid) dur-
ing operation. If the housing is not immersed
or there is air in the hydraulics, flying sparks
may cause an explosion, for example due to
static charge! Ensure that dry-running pro-
tection is in place for switching off.
In addition to the information in the 'Commis-
sioning' section, note the following points for
Ex-rated pumps:
• The operator is responsible for defining the po-
tentially explosive area. Only pumps with Ex ap-
proval may be used within a potentially explosive
area.
• Ex-rated pumps must be identified accordingly.
10.3.5. Maintenance and repair
ELECTROCUTION hazard!
There is a risk of fatal electric shocks when
performing work on electrical devices. With
all maintenance or repair work, the pump
must be disconnected from the mains and
secured against being switched on again
without permission. Damage to the power
supply cable may only be rectified by a quali-
fied electrician.
In addition to the information in the 'Maintenance
and repair' section, note the following points for
Ex-rated pumps:
• The maintenance and repair work described in
this operating and maintenance manual must be
carried out properly.
• Repairs and alterations to the construction which
are not listed in this operating and maintenance
handbook or which may impair explosion protec-
tion may only be performed by the manufacturer
or by service dealers certified by the manufac-
turer.
