Pump with single-phase AC motor
To connect the pump firmly to the switchgear, cut off the
plug. Carry out connection to a switchgear as follows:
Wire colour
Brown (bn)
Blue (bl)
Green/yellow (gn-ye)
Pump with three-phase AC motor
The pump is suitable for connection to a clockwise rotat-
ing field. Check the rotating field with a rotating-field-
testing device before connection and correct if necessary.
CAUTION! The pump is not approved for operation with
a counter-clockwise rotating field! Carry out connection
to a switchgear as follows:
Wire colour
Brown (bn)
Black (bk)
Blue (bl)
Green/yellow (gn-ye)
Adjust the motor protection
Set the motor protection switch to the rated current (see
rating plate).

Commissioning
DANGER
Risk of fatal injury due to electrical cur-
rents in accessible basins!
Do not operate the pump if there are persons
in contact with the fluid. In the event of a
fault this may cause death by electric shock!
Only activate the pump when there are no
longer any persons in contact with the fluid.
NOTICE
Check the inlet quantity!
The maximum inlet volume flow must be less
than the maximum pump delivery rate. If the
inlet quantity is higher, the pump will not be
able to pump away the volume flow. The
pump chamber may overflow!

6.1
Before activating
Check the following prior to activation:
ƒ
Has the electrical connection been carried out in ac-
cordance with regulations?
ƒ
Has the connection cable been routed safely?
ƒ
Can the float switch move freely?
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?
6.2
Switching on and off
The pump is switched on and off depending on the ver-
sion:
ƒ
Pump with plug, without float switch
The pump will switch on immediately after the plug has
been inserted into the socket. To switch off the pump,
pull the plug.
ƒ
Pump with plug and float switch
The pump will switch on and off automatically on
reaching the switching level:
–
Upper floater: Pump on.
–
Lower floater: Pump off.
ƒ
Pump with bare cable end (without plug)
Switch the pump on and off via a separate control. Read
the installation and operating instructions for the con-
trol unit for further details.
6.3
Test run
If the pump is installed stationary (e.g. cesspool, overflow
shaft), carry out a test run. Check the basic conditions
(feed quantity, switching points) with the test run. The
test run must include three pump cycles.
1. Flood the pump chamber: Open inlet.
NOTICE! The required feed quantity for the test
run can also be simulated using another water
source.
2. When the switch-on level is reached: pump starts.
3. Switch-off level reached: pump stops.
4. Repeat two more pumping processes.
▶ Once three pumping processes have been com-
pleted without problems, the test run is finished.
NOTICE! If the pump does not switch on once a week,
repeat the test run every month.
