5.4 Electrical connection
DANGER
Unintentional contact with live parts
Danger of death from electric shock!
▷De-energise the mains connection.
▷Take steps to ensure that the mains connection cannot be re-energised
unintentionally.
CAUTION
Improper electrical connection
Damage to the control unit/ control cabinet!
▷Check the type of current and voltage of the mains.
▷For connecting pump power cables with flexible cores, attach wire end sleeves
to the core ends that are to be connected to the control unit.
▷Observe the wiring diagrams. (ðSection9.1,Page19) .
CAUTION
Technical pump data not taken into account
Damage to the control unit!
▷Connect only pumps with technical data (particularly rated current) that
matches this control unit.
NOTE
Connect the thermal circuit breaker with the corresponding cores of the pump
power cable. On pumps without a thermal circuit breaker a bridge must be inserted
into the control unit.
üThe mains voltage at the site has been verified against the data on the name
plate.
üThe wiring diagram is on hand.
1. Guide the power cables through the corresponding cable glands.
2. Make sure that the sealing elements are properly positioned. Tighten the cable
glands (strain relief).
3. Connect the control unit in accordance with the wiring diagram.
4. Set the motor protection relay to the rated current.
5. For three-phase motors, connect the power cable available on site so as to
ensure a clockwise rotating field.
6. For single-phase AC motors, ensure that phase and neutral are connected
correctly.

5.4.1 Setting the level-dependent control
CAUTION
Obstructed float switch
Flooding caused by pump not stopping!
Dry running caused by pump not stopping!
▷The float switch must be fitted in such a way that it is able to move freely.
▷The pump must be started up before the fluid handled reaches the upper edge
of the tank.
▷The pump must be stopped before the fluid handled drops down to the suction
openings.
Setting the switching
points
The pump is started and stopped by a float switch or level sensor. The float switch
closes the circuit in upper float position.
▪When the fluid handled reaches the start-up level or the float switch reaches an
upper angular position of 30°, the pump starts up.
▪When the fluid handled reaches the stop level or the float switch reaches a lower
angular position of 30°, the pump stops.
▪The switching points are indicated by a clearly audible switching noise in the
float housing.
▪The switching points must be at least 40cm apart.
Routing the float switch
cable
üThe switching level is set at the site.
1. Determine the fastening height of the float switch cable at the discharge line,
handle or other suitable points.
2. Observe the required free cable length of the float switch.
3. The minimum free float switch cable length measured from the antikink bush is
10cm.
4. Fasten the float switch cable with suitable fasteners.
