5.2 Electrical connection
DANGER! Risk of fatal injury!
The electrical connection must be made accord-
ing to the local regulations (VDE regulations) by
an electrical installation engineer approved by
local energy supply companies.
• The type of current, system type and voltage of
the mains connection must correspond to the
specifications on the rating plate
• Observe the rating plate data of the pump
motors to be controlled
• Observe the fuse protection on the mains side
according to the system's rating plate
• If residual-current-operated protection
switches are used, the corresponding regula-
tions and the operating instructions for the
pump(s) to be connected are to be observed.
• Wiring is to be performed in accordance with the
wiring diagram enclosed
• Earth the pump/installation in accordance with
the regulations
• The connection lines are to be installed in such a
way that there is no contact with the pipes and
the pump and motor housings under any circum-
