DAnGEr of explosions!
If the connected signal transmitters are used in
potentially explosive areas, there is a danger of
fatal injuries from explosions! the connected signal
transmitters must always be used outside of po-
tentially explosive areas. Installation must always
be carried out by a qualified electrician.
Note the following:
• When using float switches, ensure that these can move
freely in the collector tank (sump, reservoir).
• The water level of the connected pump must not fall
below the minimum.
• The maximum switching frequency of the connected
pump must not be exceeded.

Electrical connection

PoTEnTIALLy fatal danger due to electrical voltage
Incorrect electrical connections can cause fatal
electric shocks. Electrical connections may only
be established by a qualified electrician who is ap-
proved by the local power supplier, in accordance
with locally applicable regulations.
DAnGEr - explosive atmosphere!
If the connected pump and signal transmitter are
used in potentially explosive areas, there is a dan-
ger of fatal injuries from explosions! the connected
pump and signal transmitter must always be used
outside of potentially explosive areas. Installation
must always be carried out by a qualified electri-
cian.
NOTE
• Depending on the system's impedance and the
connected consumers' max. no. of connections/hour,
voltage fluctuations or voltage drops may occur. Al-
ways have the electrical connections carried out by an
electrician authorized by the local energy supplier.
• Observe the installation and operating instructions for
the connected pump and signal transmitters.
• The mains connection current and voltage must be as
stated on the rating plate.
• All-pole disconnecting, K-type circuit breakers must be
installed!
• Max. fuse protection on mains side: 16 A
• It is recommended a residual-current-operated protection
switch (RCD, type A, sinus wave-form current) be installed.
Observe the local laws and regulations on this too!
• Route the power supply cable in accordance with the
valid norms and regulations and according to the wiring
diagram.
• Ground the system (switchgear and all electric consumers)
in accordance with the regulations.

5.4.1. Switchgear mains connection
Insert the cable ends of the power supply cables laid onsite
through the threaded cable connections and secure them accord-
ingly.
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 connected to
the ground terminal (;).
• Mains connection 3~400 V:
• Cable: 5-core
• Terminals: 2/T1 (L1), 4/T2 (L2), 6/T3 (L3)
• The protective ground conductor (PE) is connected to
the ground terminal (;).
• A clockwise rotating field must be present!
5.4.2. 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 connected to
the ground terminal (;).
NOTE
With the S version, the pump is connected at termi-
nals 2/T1 (N), 4/T2 (L)!
• Pump connection 3~400 V:
• Terminals: 2/T1 (U), 4/T2 (V), 6/T3 (W)
• The protective ground conductor (PE) is connected to
the ground terminal (;).
• A clockwise rotating field must be present!
After the pump has been connected correctly, the motor protec-
tion needs to be adjusted.
Adjusting the motor protection
The electronic motor protection monitors the rated current of the
connected pump during operation. Deactivation occurs immedi-
ately if the set rated current is exceeded.
NOTE
With connection of 3-phase current motors, deac-
tivation also occurs after 10 secs if the rated current
drops below 300 mA during operation!
