Pump with plug
The pump is equipped with a CEE motor protection plug. The
connection to the mains is established by inserting the plug into
the socket. The plug is not watertight.
The thermal motor monitoring (bimetallic strip) is connected in
the motor protection plug. When the max. winding temperature
is reached, the pump is deactivated. Reactivation must be done
manually. Separate connection of the motor monitoring is not
necessary.
If the pump is directly connected to the switchgear, disconnect
the plug. Connect the connection cable according to the connec-
tion diagram in the switchgear.

NOTICE
Automatic activation after power cut
Depending on the process, the product is switched
on and off using separate controls. The product
may automatically switch on following power cuts.
7.1 Personnel qualifications
ƒ
Operation/control: Operating personnel, instructed in the
functioning of the complete system
7.2 Operator responsibilities
ƒ
Providing installation and operating instructions by the pump
or at a place specially reserved for it.
ƒ
Making the installation and operating instructions available in
the language of the personnel.
ƒ
Making sure that the installation and operating instructions
are read and understood by all personnel.
ƒ
All safety devices and emergency cut-outs on the system-
side must be active and checked to ensure that they work
properly.
ƒ
The pump is suitable for use under the specified operating
conditions.
7.3 Direction of rotation check for three-phase AC motor
The pump has been checked and adjusted to the correct direction
of rotation at the factory. To allow the correct direction of rota-
tion, a clockwise rotating field must be available at the mains
connection. The pump is not approved for operation with a
counter-clockwise rotating field!
ƒ
Check the direction of rotation.
Check the rotating field at the mains connection with a rotat-
ing-field testing device.
ƒ
Correct the direction of rotation.
Switch two phases.
7.4 Before switching on
Check the following prior to activation:
ƒ
Has the electrical connection been carried out in accordance
with regulations?
ƒ
Has the connection cable been routed safely?
ƒ
Can the float switch move freely?
ƒ
Accessories attached correctly?
ƒ
Temperature of the pumped fluid observed?
ƒ
Immersion depth observed?
ƒ
Are the pressure pipe and pump sump free of deposits?
ƒ
All gate valves in the pressure pipe open?
ƒ
Are ventilation systems present in the pressure pipe?
Air pockets in the pump and in the pressure pipe can lead to
delivery problems.
7.5 Switching on and off
ƒ
When the pump starts, the rated current is exceeded for a
short time.
ƒ
During operation, do not exceed the rated current any more.
CAUTION! Material damage! If the pump does not start, switch
off the pump immediately. Motor failure! Remove the fault
first before reactivation.
Observe the following points for transportable installation:
ƒ
Place the pump on a firm bearing surface. Avoid sinking!
ƒ
If the pump has fallen over, place it upright again before activ-
ating it.
ƒ
If the pump “moves away”, screw the pump to the ground.
