3.4 Protection of the electronic control system
• All assembly work (connection and disconnection of sensors, valves, control box etc., replacement of
fuses) must be carried out with the power supply switched off.
• The control is designed for 12 Volt operation. Operation with other on-board power supplies is not
permissible!
• The correct polarity of the power supply of the tractor
must not be changed, otherwise the electronic
control could be damaged.
• In case of welding work on the baler:
- Do not permit welding current to flow through the control unit;
- Interrupt power supply between tractor and baler;
- Take heat generation at the welding points into account;
if necessary remove sensitive parts (cables, sensors or the like) prior to welding.
3.5 Electromagnetic compatibility (EMC)
The machine is equipped with electronic components and modules; the function of these electronic
components and modules can be influenced by electromagnetic emissions of other equipment. Such
influences can cause risks to persons, if the following safety instructions are not observed:
In case of subsequent installation of electrical and electronic equipment and/or components into the
machine, with connection to the central mains, it is the user's responsibility to check whether the
installation impairs the vehicle electronics or any other components.
Ensure above all that the electrical and electronic components subsequently installed are in conformity
with the EMC directive 89/336/EEC as amended, and that they are provided with the CE.
