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 carried out by a qualified electrician approved
by the local energy supply company, in accordance
with locally applicable regulations.
DANGER of explosions!
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.
Always have the electrical connections carried out by
an electrician authorised by the local energy supply
company.
• 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: 25 A (16 A for S ver-
sion with shock-proof/CEE16 plug)
• On switchgears without a power supply separation device
(O version: without main switch or plug) this must be pro-
vided by the customer!
• 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. DIP switch

The switchgear has two DIP switches. These are used to switch
various functions on/off:
• DIP switch 1, above the potentiometer
This DIP switch is used to adjust the rated current for
motor protection as well as activating or deactivating the
pump kick function and the internal buzzer.
• DIP switch 2, under the potentiometer
This DIP switch is used for stipulating the service intervals
and activating/deactivating the connected pumps as well
as for monitoring the operating parameters (S version
only).
5.4.2. Switchgear mains connection:
Insert the cable ends of the power supply cable laid onsite through
the threaded cable connections 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 earth conductor (PE) is connected to the
ground terminal (;).
• Mains connection 3~400 V:
• Cable: 4-core
• Terminals: 2/T1 (L1), 4/T2 (L2), 6/T3 (L3)
• The protective earth conductor (PE) is connected to the
ground terminal (;).
• A clockwise rotating field must be present!
5.4.3. Pump mains connection
Insert the cable ends of the pump power supply cables laid onsite
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 connected to the
ground terminal (;).
NOTE
With the S version, the pump is connected at termi-
nals 2/T1 (N), 4/T2 (L)!
