Electrical installation

WARNING!
Danger of electric shock
A mains voltage may exist inside the device.
– Before any work, disconnect the device's mains
cable from the mains.
WARNING!
Risk of electric shock
This pump is supplied with a grounding conductor and a
grounding-type attachment plug.
– To reduce the risk of electric shock, ensure that it is
connected only to a proper grounding-type recep‐
tacle.
WARNING!
Risk of electric shock
In the event of an electrical accident, the pump must be
quickly disconnected from the mains.
– Install an emergency cut-off switch in the pump
power supply line or
– Integrate the pump in the emergency cut-off man‐
agement of the system and inform personnel of the
isolating option.
WARNING!
Danger of electric shock
A mains voltage may exist inside the pump housing.
– If the pump housing has been damaged, you must
disconnect it from the mains immediately. It may
only be returned to service after an authorised
repair.
CAUTION!
Material damage possible due to power surges
Should the pump be connected to the mains power
supply in parallel to inductive consumers (such as sole‐
noid valves, motors), inductive power surges can
damage the control when it is switched off.
– Provide the pump with its own contacts (Phase) and
supply with voltage via a contactor relay or relay.
– Should this not be possible, then switch a varistor
(part no. 710912) or an RC gate (0.22 µF/220 Ω,
part no. 710802) in parallel.
