 CONNECT2 electronic control
In order to establish the unit's electric power supply (cable inlet,
calculation of the lead section, protections etc.), refer to:
- The information supplied in this document (table of technical
characteristics).
- Data plate.
- The wiring diagram and the legend supplied with the unit.
- The electronic control brochure which is supplied with the unit.
- The regulations and norms in force which regulate the installation of
air-conditioning units and electric receivers.
The electric power supply of the unit must be sized in accordance with
the maximum power input by the unit taking into account all the options
it features (if necessary, refer to the technical brochure).
Verify that electrical power corresponds to the one on the data plate
and that the voltage remains constant.
Check that the electrical connections are correct and tight
(an electrical diagram is included with each unit, along with
its legend).
Note: All connections in the site are the responsibility of the
installer. These connections are always made as per the
current regulation.
To prevent electrical shocks, make all electrical connections
before energizing the unit. Check that the automatic switch
is closed. Omitting this can cause personal damage. Make
the ground connection before any other electrical connection.
