ATTENTION
The electrical connections are made after completing all hydraulic connections.
ELECTRICAL WIRING
The internal and external units must be powered separately according to what is indicated on the tables of the standard NF C 15-100. Between
the internal and external units should also be made a connection RS485. This connection may be made through the use of a cable of reduced
section (recommended section 0,25 mm2). Do not let this cable walk along a power connection.
Electrical circuit
Check that the voltage and frequency of power supply from the network, coincide with the data shown in the data plate of the appliance (see
table «Technical Data»)
In order to ensure greater security, the main electrical system should be checked by a qualifi ed technician before proceeding with the installation.
(see note)
The manufacturer is not liable for any damage caused by installation with improper grounding or abnormalities in the electrical system.
Check that the installation is adequate to support the power consumption of the installed units, indicated on the data plate of the product.
The electrical connections must be carried out with the aid of a fi xed supply connection (do not use mobile sockets) and equipped with a bipolar
switch, having a distance between the contacts of at least 3 mm.
It is essential to connect the appliance to a correctly grounded electrical, as to ensure the safety of the installation.
Connect the power cord to a 230V-50Hz, verifying the polarizations of the L-N connection and the connection to the earth. The section of the
cables used must comply with the power of the installation (see plate characteristic) according to standard NF C 15-100.
For the electrical connection of the installation, you may not use power strips, extension cords and adapters. It is also prohibited to use the
hydraulic pipes and heating system pipes to ground the installation.
The system is not protected against lightning. If you need to change the fuses, use fast fuses.
Warning: Before obtaining access to terminals, all supply circuits must be disconnected.
