5.6 Electrical connection
The control panel and electrical connections must be carried out by skilled personnel
and conform to the EN 60204-1 rules or to other local regulations in the Country of use.
The electrical equipment must comply with EN 61000-6-4 and EN 61000-6-2 standards
concerning electromagnetic compatibility, emission standard and immunity for industrial
environment.
Check the main voltage and frequency in use to correspond to the data stamped on the
motor name plate.
The electric motor must be protected against overload. The full load amperage value on
the motor name plate must be considered when sizing the electrical components and
motor protection against overloading.
Make sure the grounding is correctly done.
Carry out the electric connection following the diagram shown on the motor terminal box.
Check direction of rotation by starting the pump for a short time (2-3 seconds). The
correct direction is shown by the arrow on the pump (figure 7). In case of wrong rotation,
it is necessary to change the motor rotation by exchanging position of two of the three
connections previously connected to the motor terminal box.
