Power Supply; Installation Of Control Unit Brackets - Hardi NEPTUN Series Instruction Book

As this manual does not refer to only one model, since HARDI off ers multiple confi gurations of the same sprayer, the
following chapter refers to the available operating units.

Power supply

Power requirement is 12V DC. Always note polarity! For proper function of the electric equipment, the wires must have the
following recommended cross sectional areas and correct fuses to ensure a suffi cient power supply. The delivered power
connectors follow the standard of most of the newest tractors. If you have a tractor with another power connector, it is
necessary to disassemble the connector and fi t it to the actual tractor connector. The number and the type of connectors
may vary depending on the specifi cations.
When 12 V power is taken from other places than the battery, it often
changes in voltage when other power consumption is activated (Air
condition on / off ventilator on the radiator on/ off etc.) That assistance
in voltage does aff ect the Spray Computer.

Installation of control unit brackets

Find a suitable place in the tractor cabin to mount the control units. Best
recommended position is to the right of the driver seat.
The supplied tractor pillar bracket (A) has a hole spacing of 100 and 120
mm that fi ts most tractors. Threaded mounting holes may be hidden
behind the front corner cover. Check tractor instructions manual for
information regarding attachment points. Three mounting tubes (B)
are supplied. One, two or all three may be used. They can be bent and
shortened. A spacer (C) is also supplied to allow further attachment
possibilities. Find the best solution for your tractor or vehicle. Tube (B)
plate is prepared so that, if correctly orientated, all boxes will line up.
DANGER! turn off any spray computer before you unplug the
power supply and cable to the sprayer.
Data transmission must stop, before power supply is stopped.
