7.1.3 Stationary dry sump installation, for pump with cooling
jacket only (FIG. 4)
Pos. Description of the component
2 Non-return valve
3 Gate valve
17 Installation set
18 Compensator
•The fixed pipe connections on the pressure side must be pro-
vided on site.
•The weight of pipes and fittings must not be carried by the
pump and compensators and must be intercepted through
the use of suitable fixings.
•A resonance-free pump installation must be ensured on site.
The pipes must be supported at suitable intervals to prevent
inadmissible vibrations. The use of suitable compensators is rec-
ommended for decoupling the pump.

7.2 Electrical connection

DANGER! Risk of fatal injury!
If the electrical connection is not made properly, there
is a risk of fatal injury from an electric shock.
•Only allow the electrical connection to be made by an
electrician approved by the local electricity supplier
and in accordance with the local regulations in force.
•Follow the installation and operating instructions for the
pump, level control device and other accessories.
Preparation of the electrical connection
•Make sure that the type of current and voltage of the mains
connection corresponds to the details on the name plate.
•Protect the connection on the mains side: 16 A, slow or auto-
matic fuse with C characteristic.
•Earth the system according to regulations.
•Use a ≤ 30 residual current circuit-breaker.
•Use an isolating device with a min. 3 mm contact opening to
isolate from the mains.
•Connect the pump.
7.2.1 Pump with single-phase motor (1~230V)
•The motor is already wired with the condenser box at the
works. The mains connection is made at terminals L1, N, PE of
the terminal box.
•According to DIN EN / IEC 61000-3-11, the pump is designed
with a power of 1.5 kW for operating on a power supply mains
with a system impedance Zmax on the house connection of
maximum 0.118 (0.086) Ohm with a maximum number of 10
(20) connections.
•Number of connections, see 5.2 of the Technical data.
NOTE: If the mains impedance and the number of con-
nections per hour is greater than the values specified,
because of the unfavourable mains connections, the
pump may lead to temporary voltage drops and also
to disturbing voltage fluctuations, or flickering.
Therefore, measures may be necessary before the
pump can be operated correctly on this connection.
The necessary information must be obtained from the
electricity supply company and the manufacturer.
7.2.2 Pump with three-phase motor (3~400V):
•The use of a residual current circuit-breaker is recommended.
•The switchbox for the pump(s) is available as an accessory.
CAUTION! Danger of property damage!
Risk of damage through incorrect electrical connec-
tion.
If the switchbox is provided by the customer on site, the
following requirements of the electricity supply compa-
nies must be met.
≤ 4 kW: Direct starting:
– P
2
– Set the motor protection switch to the nominal current of
the motor according to the name plate.
– For the thermal monitoring of the motor, a standard evalu-
ation device can be used to connect the thermal winding
contact. Connect with 230V AC, max. 1A, recommended:
24V DC
Connecting cable
•Allocate the connecting cable wires as follows:
≤ 1.5 kW:
Pumps with P
2
6-wire connection cable: 6x1.0 mm²
Wire no. 1 2
Terminal U V
Pumps with P = 1.5 kW to 4.0 kW:
2
7-wire connection cable: 6x1.5 mm²
Wire no. 1 2 3
Terminal U V W
Wire the free cable end in the switchbox (see Switchbox instal-
lation and operating instructions).
8. COMMISSIONING
DANGER! Danger through electric shock!
The pump must not be used for draining swimming
pools, garden ponds or similar installations if anyone is
in the water.
CAUTION! Danger of property damage!
Before installation, clear the pond and the supply pipes
of all solid materials such as rubble.
8.1 Checking the direction of rotation (three-phase motors
only)
WARNING! Risk of injury!
•Jerking occurs when the freely suspended pump is
switched on. People may be injured if the pump drops
down. Make sure that the pump is safely suspended
and cannot drop down.
•The rotating impeller creates an increased risk of injury.
Do not reach into the pump housing during operation.
The pumps are checked for the correct direction of operation
and set at the works.
Check that the pump is rotating in the correct direction before
submersion.
•To do this, suspend the pump safely in a hoist.
•Switch the pump on briefly. The pump recoils in the opposite
direction (anticlockwise) to the motor's direction of rotation.
