5.4.1. Switchgear mains connection
Insert the cable ends of the power supply cable
laid on-site through the threaded cable connec-
tions and secure them accordingly.
Connect the wires to the terminal strip according
to the wiring diagram.
The protective earth conductor (PE) is connected
to the ground rod.
• Mains connection 3~380/400 V, 50/60 Hz
• Rotating field: clockwise
• Cable: 4-core
• Wire: L1, L2, L3, PE
NOTE
The switchgear has an integrated monitoring
of the rotating field. The switchgear must be
connected to a clockwise rotating field so that
the switchgear operates correctly. If there is
no clockwise rotating field, error code "E06"
appears on the display.
5.4.2. Pumps mains connection
Insert the cable ends of the pump power supply
cable laid on-site through the threaded cable
connections and secure accordingly.
Connect the wires to the terminal strip according
to the wiring diagram.
The protective earth conductor (PE) is connected
to the ground rod.
• Supply voltage: 3~380/400 V, 50/60 Hz
• Activation: Direct
• Wire: U, V, W, PE

NOTE
The rotating field is routed directly to the pump
connection by the mains connection. Note the
required rotating field of the connected pumps
(clockwise or counter-clockwise)! Observe the
installation and operating instructions for the
connected pumps.
After the pumps have been connected correctly,
the motor protection needs to be adjusted and
the pump enabled.
Adjusting the motor protection
The max. permissible motor current must be set
directly on the motor protection switch.
• At full load, the motor protection should be set to
the rated current shown on the rating plate.
• At partial load, we recommend that the motor
protection be set 5 % above the current meas-
ured at the duty point.
Pumps enabled
Set the separate (HAND-0-AUTO switch) oper-
ating mode switch to "AUTO (A)" for every pump.
This is factory-set to the position "0 (OFF)".
You can find the operating mode switch on the
front side of the switch cabinet.
5.4.3. Winding temperature monitoring connection
One temperature monitoring can be connected
to each connected pump by means of bimetallic
strip.
Connect the wires to the terminal strip according
to the wiring diagram.
NOTE
No external voltage may be applied!
5.4.4. Leakage detection connection
Two leakage detection can be connected per
connected pump by means of a moisture probe.
The threshold value is fixed in the switchgear.
Connect the wires to the terminal strip according
to the wiring diagram.
NOTE
No external voltage may be applied!
5.4.5. Connection for level measurement signal trans-
mitter
The level is measured via the level sensor. Con-
nection of float switches or electrodes is not
possible!
Insert the cable ends of the cable laid on-site
through the threaded cable connections and
secure accordingly.
Connect the wires to the terminal strip according
to the wiring diagram.
