NOTE
To function correctly, 2 bridges (supplied) must
be installed on the mains terminal strip:
• Terminal 1 and 2
• Terminal 3 and 4
• Mains connection 3~400 V:
• Cable: 5-core
• Terminals: 2/T1 (L1), 4/T2 (L2), 6/T3 (L3), N (N)
• The protective earth conductor (PE) is connect-
ed to the earth terminal (;).
• DIP switch 2: DIP position "1": ON (top position)
• A clockwise rotating field must be present!
5.4.3. Switchgear mains connection - with plug ("S"
version)
Insert the plug into the socket:
• Mains connection 1~230 V: Shock-proof socket
• Mains connection 3~400 V: CEE socket (a clock-
wise rotating field must be present)
5.4.4. Switchgear mains connection - without main
switch and plug ("O" version)
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 on the mains terminal strip as
follows:
• Mains connection 1~230 V:
• Cable: 3-core
• Terminals: L1 (L), N (N)
• The protective earth conductor (PE) is connect-
ed to the earth terminal (;).
• DIP switch 2: DIP position "1": OFF (bottom
position)

5.4.5. Pump mains connection
Insert the cable ends of the pump power supply
cables laid on-site through the threaded cable
connections and secure accordingly.
Connect wires as follows to the motor protection
for the relevant pump (P1, P2):
• Pump connection 1~230 V, 3-core cable:
• Terminals: 4/T2 (L), 6/T3 (N)
• The protective earth conductor (PE) is connect-
ed to the earth terminal (;).

NOTE
With the "S" version the pump is connected at
terminals 2/T1 (L), 4/T2 (N).
• Pump connection 3~400 V:
• Terminals: 2/T1 (U), 4/T2 (V), 6/T3 (W)
• The protective ground conductor (PE) is con-
nected to the earth terminal (;).
• A clockwise rotating field must be present!
After the pumps have been connected correctly,
the pumps need to be activated and the motor
protection adjusted.
Activating pumps
The connected pumps have to be switched on via
DIP switch 2, DIP 6 and 7. The factory setting for
the DIP switches is OFF. Level-control dependent
activation of pumps is not possible in this setting.
• DIP 6 ON: Pump 1 activated
• DIP 7 ON: Pump 2 activated
Adjusting the motor protection
The electronic motor protection monitors the
rated current of the connected pumps during
operation. Deactivation takes place immediately
if the set rated current is exceeded.
NOTE
With connection of 3-phase current motors,
deactivation also occurs after 1 sec. if the rated
current drops below 300 mA during operation!
After each deactivation, the fault needs to be
acknowledged via the "Reset" button.
The motor protection needs to be set to the rated
current shown on the rating plate.
The desired rated current is set via DIP switch 1,
DIP 1-5. The lowest current value is 1.5 A in which
all DIP switches are set to OFF position. On acti-
vating the individual DIP switches (ON position),
the current value is increased by the value of the
relevant DIP switch.
DIP 1
Current value 0.5 A 1.0 A
Example: Required rated current 7.5 A
1.5 A + 2.0 A (DIP 3) + 4.0 A (DIP 5) = 7.5 A
5.4.6. Winding temperature monitoring connection
Bimetallic strips may be connected for tempera-
ture monitoring.
Monitoring is self-acknowledging, meaning that
after the motor has cooled down the error is reset
automatically and the LED goes off.
Connect the wires to the terminals for the corre-
sponding pump at the terminal strip:
• Pump 1: Terminal 1 and 2 (WSK-P1)
• Pump 2: Terminal 3 and 4 (WSK-P2)
