NOTICE:
Only use single
-phase or three-phase motors with sizes and powers in compliance with
European standards.
NOTICE:
The mains voltage and frequency must match the specifications on the data plate.
Electrical connection of the motor

Motor without automatic reset thermal overload protection
• If the motor is used with full load, then set the value to the nominal current value on the
data plate of the pump unit.
• If the motor is used with partial load, then set the value of the operating current measured
with a current pincer.
• For three-phase motors with star-delta starting system, set the thermal relay downstream of
the switching circuit at 58% of the rated or operating current.
