5.1 Location
Install the pump so that the inlet (5) and the outlet (6) are at least 20 cm away from
the closest walls.
Oil filling port (1), oil sight glasses (2) and oil drainage ports (3) must be easily accessible.
5.2 Electric connection
The control panel and electric 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 electric equipment must comply with EN 61000-6-4 and EN 61000-6-2 standard
concerning electromagnetic compatibility, emission standard and immunity for industrial
environments.
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. In case of wrong rotation, it is necessary
to change the motor rotation by exchanging position of two of the three connections in
the motor terminal box.
