CAUTION! Danger of material damage!
Connecting the motor incorrectly can damage it!
• Check the mains voltage
• Do not cut the cable between the switchbox and
pump. The switchbox contains the necessary
motor capacitors (EM versions only).
• Fit ground
• Motor protection is regulated by a thermal or
magnetic switch (fitted on EM version, to be fitted
on the DM version)
8 Commissioning
8.1 Direction of rotation check (three-phase
motors only, the direction of rotation cannot be
confused on single-phase motors)
In order to define the correct direction of rotation,
it suffices to check the water pressure on the
pressure side of the pump that is running.
