DANGER! Danger of death!
The switchgear is not protected against explo-
sions and may not be operated in the explosive
area.
Always install the switchgear outside the explo-
sive area.
Correct use of the pump/installation also includes
following these instructions.
Any use over and beyond these is considered to be
incorrect use.

high water level is reached, optical and acoustic
signals are output and there is a forced pump
switch-on. The collective fault signal is active.
An optional rechargeable battery (accessory)
allows for a mains-independent alarm signal,
which signalises the missing mains voltage by
means of a continuous acoustic signal.
Pump faults are registered and evaluated.
The display of the operating states is signalised by
LEDs on the front side. Operation is done via but-
tons on the right side on the housing.
The switchgear is delivered for single-phase cur-
rent (1~230 V) with a shock-proof plug and an
integrated operating capacitor, or for three-phase
current (3~400 V) with a CEE plug with phase
inverter.
