3 Terminal strip
4 Ground terminals
5.4.1. Switchgear mains connection: with main switch
Insert the cable ends of the power supply cables
laid onsite through the threaded cable connec-
tions and secure them accordingly.
Connect the wires to the main switch as follows:
• Mains connection 1~230 V:
• Cable: 3-core
• Terminals: 2/T1 (L), N (N)
• The protective ground conductor (PE) is con-
nected to the ground terminal (;).
• Position of DIP switch 8: OFF (down position)
NOTE
For correct operation, 2 converter bridges
(enclosed) must be installed on the network
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 ground conductor (PE) is con-
nected to the ground terminal (;).
• Position of DIP switch 8: ON (top position)
• A clockwise rotating field must be present!
5.4.2. Switchgear mains connection: with plug (S
version)
Insert the plug into the socket:
• Mains connection 1~230 V: Safety socket
• Mains connection 3~400 V: CEE socket (A clock-
wise rotating field must be present)!
5.4.3. Switchgear mains connection: without main
switch and plug (o version)
Insert the cable ends of the power supply cables
laid onsite through the threaded cable connec-
tions and secure them accordingly.
Connect the wires to the network terminal strip
as follows:
• Mains connection 1~230 V:
• Cable: 3-core
• Terminals: L1 (L), N (N)
• The protective ground conductor (PE) is con-
nected to the ground terminal (;).
• Position of DIP switch 8: OFF (down position)

• The protective ground conductor (PE) is con-
nected to the ground terminal (;).
• Position of DIP switch 8: ON (top position)
• A clockwise rotating field must be present!
5.4.4. Pump mains connection
Insert the cable ends of the pump power supply
cables laid onsite through the threaded cable
connections and secure accordingly.
Connect the wires to the motor contactor as
follows:
• Pump connection 1~230 V, 3-core cable:
• Terminals: 4/T2 (L), 6/T3 (N)
• The protective ground conductor (PE) is con-
nected to the ground 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 ground terminal (;).
• A clockwise rotating field must be present!
After the pump has been connected correctly, the
motor protection needs to be adjusted.
Adjusting the motor protection
The electronic motor protection monitors the
rated current of the connected pump during
operation. Deactivation occurs immediately if the
set rated current is exceeded.
NOTE
With connection of 3-phase current motors,
deactivation also occurs after 10 secs 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 switches
1-5. The lowest current value is 1.5 A where 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.
