The free cable end is to be wired up in the switch
box (see switch box Installation and Operating
Instructions).
Pump with single-phase motor (1~230V):
• Single-phase current connection: The motor is
already factory-wired to the terminal box. The
mains connection is made via terminals L, N, PE.
• In acc. with DIN EN / IEC 61000-3-11 the pump is
to be provided with a rating of 1.5 kW for opera-
tion in a power supply with a system impedance
Z on a line connection of max. 0.125 (0.086)
max
Ohm at a maximum number of 6 (20) switching
operations.
If the supply impedance and the number of
switching operations per hour exceed the above-
mentioned values, the pump can lead to transient
voltage reductions and interfering voltage fluctu-
ations, or "flicker", because of the unfavourable
supply conditions.
Measures may therefore be required before the

pump can be operated properly on this connec-
tion; relevant information is to be obtained from
the local electricity company and the pump man-
ufacturer.
8 Starting-up
CAUTION! Risk of damage to the pump!
Prior to starting up the pump, the shaft and the
intake pipes should be freed from solid matter
such as rubbish.
8.1 Direction of rotation (only for three-phase
motors)
The correct direction of rotation must be tested
before the pump is submerged. This is indicated
by the arrow showing the direction of rotation on
the pump housing.
• Hang the pump in the hoist.
• Briefly switch on the pump. The pump will move in
the opposite direction to the motor (arrow on
housing).
• If the direction of rotation is incorrect, 2 phases of
the mains connection must be exchanged.
8.2 Adjusting the control level
Adjusting the control level: see instructions for
assembly and installation of the control level.
CAUTION! Risk of damage to the pump!
Dry running destroys the mechanical seal.
The pump must not be allowed to run dry and to
suck any air.
The "OFF" position (H
depends on the pump type and/or the operating
mode (Fig. 1, 2, 3).
