6 RECOMMENDATIONS
Controller location
• Install the controller at the proper height and
position for good handling.
• Avoid as much as possible the direct incidence of
the sun, humidity, dust and vibrations.
• Avoid being close to elements that generate inter-
ference and may aect the proper functioning.
• To maintain the tightness of the bos format, it is
necessary to keep the lid always closed, as well as
to install cable glands in the outlets of the cables.
Installation with frequency inverter
• The ground of the Agrónic must be independent
and separate the ground spike from the drive and
the engine.
• The sensor cables must be shielded and installed
separately from the power cables.
• It is highly recommended to install the Agrónic and
the drive in distinct and separate cabinets.
• Between the drive and the motor it is advisable to
put a filter to reduce the harmonics of the signal
exit, and thus comply with the CE marking regula-
tions. The filter must be located close the inverter,
as well as use shielded cable (EMC).
• In installations that have a pressure transducer, it
must be galvanically isolated from the pressure
pipe, since interference can propagate through it.
The tranducer can be attached b means of an in-
sulating support to the wall and connected to the
pressure pipe by means of a microtube.
• In the Agrónic 4500, the consequences of a bad
installation of the drive can be the random activa-
tions of outputs, screen changes without touching
the keyboard and poor reading of probes, among
others.
• Consult the manual “Installations with Agrónics
and frecuency inverters” available on the Progrés
website.
Wiring of sensors and meters
• Sensor and meter cables must never pass together
or parallel to cables with alternating current,
there must be a minimum distance of 0.5 meters
between them.
