Motor protection

The motor protection is integrated in the frequency converter:
We also recommend installing a residual-current device (RCD).
Local and national regulations must be observed when connecting the pump.
6.5. Installation
DANGER: heights!
When installing the pump and its accessories, work
is sometimes performed directly at the edge of the
well or tank. Carelessness and/or wearing inappro-
priate clothing may result in a fall. There is a risk of
fatal injury! Take all safety precautions to prevent
a fall.
Observe during pump installation:
• This work must be carried out by qualified personnel and electrical work must be carried
out by an electrician.
• The operating space must be clean, free of coarse solids, dry, frost-free and, if neces-
sary, decontaminated. It must also be suitable for the particular pump. There must be
sufficient water inflow for the submersible pump's maximum output in order to prevent
dry run and/or air intake.
• When working in tanks, wells or boreholes, a second person must be present for safety
reasons. If there is a risk of toxic or asphyxiating gases building up, the necessary pre-
cautions must be taken.
