For pumps fitted with a seal monitoring device (DI):
DI connection max. 30 V DC at max. 30 mA
ATTENTION!
The customer must ensure that the pump is bled using a suitable automatic bleeding
mechanism so as to ensure that the pumping process starts as soon as the switching level
is reached. The supply to the shaft must be designed to prevent air from entering into the
pump hydraulics.
ATTENTION!
Do not use frequency converters (FC).
Ensure the pump cable does not snap during laying and that all other wires and insulation
materials do not suffer damage caused by vibrations or rubbing during operation of the
pump.

WSK and DI are offset against the protective earth (PE). Only galvani-
cally separated or non-earthed control voltages can therefore be used.
Do not allow the pump to run dry.
Subject to technical alterations!
