of the local electricity supply authority and a qualified person should check that these are in perfect
order.
ATTENTION The power supply system on site must comply with VDE or other local regulations
with regard to cross-sectional area and maximum voltage drop. The voltage stated on
the nameplate of the pump must correspond to that of the mains.
The power supply cable must be protected by an adequately dimensioned slow-blow fuse corresponding to the
rated power of the pump.
c
The incoming power supply as well as the connection of the pump itself to the terminals on the control
panel must comply with the circuit diagram of the control panel as well as the motor connection
diagrams and must be carried out by a qualified person.
All relevant safety regulations as well as general good technical practice must be complied with.
ATTENTION For use in the open air, the following VDE regulations apply:
Submersible pumps used outdoors must be fitted with a power cable of at least 10 metre length. Other
