WARNING
Performs only genset control and command functions. It controls the mains and generator contactors for user power supply. It is
designed solely to be built into an electrical panel and connected to the other components (contactors, fuses, thermal magnetic
switches, etc.) the installer has arranged to complete the system.
Attention: Parts powered with dangerous voltages
The control unit can only be accessed by specifically assigned, duly trained personnel. Maintenance
operations cannot be performed unless the system is disconnected from the mains and the battery. As an
additional protection measure, we recommend grounding the system phases.
Notwithstanding the above, only specifically assigned, duly trained personnel can perform the following
operations with the system powered:
- visual inspection of control unit connections and markings;
- taking voltage and/or current measurements;
- function programming.
These works must always be performed using equipment that ensures appropriate electrical protection.
Warning:
Compliance with the following recommendations is obligatory
- Always make connections following the wiring diagram shown on page 12-13.
- All works performed on the unit must be carried out with the engine off and with starter motor terminal 50 disconnected.
- Check the consumption of the connected devices is in line with the described technical specifications.
- The installation must always guarantee adequate dissipation of heat.
- Always install the device at a lower position than any other devices that produce or dissipate heat.
- Handle and connect without exposing the electronic circuit board to mechanical strain.
- Do not let cuttings of copper conductors or other metal residues drop onto the control unit.
- Never disconnect the battery terminals while the engine is running.
- Strictly avoid using a battery charger for emergency start-up; this could damage the control unit.
- To safeguard persons and equipment, always disconnect the electrical system terminals from the battery poles before
connecting an external battery charger.
THIS UNIT IS NOT SUITABLE FOR WORKING UNDER CONDITIONS WHERE:
- The room temperatures exceeds the limits specified in the technical data sheet.
- Abrupt shifts in temperature and air pressure produce exceptional condensation.
- There is high pollution caused by dust, fumes, vapour, salts and corrosive or radioactive particles.
- There is high radiation of heat due to direct sunlight, ovens or the like.
- You suspect the presence of mould or pests.
- There is a danger of fire or explosion.
- Strong shocks or vibrations can be transmitted to the control unit.
- The control unit is protected by barriers or casings with a protection rating below IP40.
ELECTROMAGNETIC COMPATIBILITY
This control unit works correctly only if it is installed in systems that comply with regulations governing CE marking; in fact,
it complies with the immunity requirements given in EN61326-1, but this does not rule out the possibility that
malfunctions could occur in extreme cases that may arise in particular situations.
The installer is responsible for checking that the level of perturbation does not exceed that specified in standards.
OPERATION AND MAINTENANCE
We recommend the following maintenance on a weekly basis:
- signal operation checks;
- battery status checks;
- conductor tightness and terminal status checks.
IN THE ABSENCE OF OUR WRITTEN DECLARATION ATTESTING TO THE CONTRARY, THIS UNIT IS NOT SUITABLE FOR USE AS A
CRITICAL COMPONENT IN EQUIPMENT OR SYSTEMS VITAL TO THE LIFE OF PEOPLE AND OTHER LIVING THINGS.
YOUR ELECTRICIAN MAY TELEPHONE OUR TECHNICAL SERVICE WITH ANY QUESTIONS REGARDING THIS CONTROL
