Assembly and connection manual | Agrónic 4500
4 CONNECTION
4.1. POWER CONNECTION
4.2. GROUND CONNECTION
Power
Power is 12 Vdc for all models.
In installations with a solar panel, generator set or diesel
motor pump, it will be connected to the 12 Vdc battery.
Ground
The installation must be carried out in accordance with current regulations for electrical installations. The protection of
the controller will not be ensured if it is not used as specified in this manual.
The Agrónic must be installed far from sources of interference such as frequency inverters, motors or power cables.
Sensor and communication cables should never pass next to alternating current cables and should preferably be
shielded. All the connection terminals of the Agrónic 4500 are pluggable, wich allows quick maintenance.
In 110 or 230 Vac systems, a 90-230 Vac / 12 Vdc (50-60Hz)
power supply is available as an accessory to connect the
controller. The socket outlet to which connect the power
should be easily accessible.
The power input has a self-resettable thermal fuse, it is
also protected against polarity inversion and overvolta-
ge peaks.
It is necessary to have an independnet magnetothermic
switch in the installation that protects the Agrónic 4500.
The general power and the transformer that power the
outputs will be connected at its output.
When a diesel engine is running avoid disconnect the
battery as the alternator would considerably increase
the supply voltage and damage the Agrónic.
The ground terminal is located next to the power
terminals. Its function is to direct possible electrical
sparks generated by storms to the ground and that may
enter through the input and output cables; arc striking
in the internal gas discharge tube occurs from 90 volts.
It is very important to connect this socket, independent-
ly, for a complete protection of the controller.
In the built-in model there is an additional earth connec-
tion on the side of the metal box in case it is necessary
to derive i to earth.
The earth connection must be distinct and separated
from the grounding of drives or motors.
