ELECTRICAL CONNECTION
5.1 - PRELIMINARY OPERATIONS
Before proceeding with the electrical connection, it is necessary to remove the front panel of the appliance.
Disconnect the earth cable before removing the front panel.
Before carrying out any electrical connection, make sure that power supply is disconnected by the
units and that the systems to which the equipment must connect are compliant with the current
standards.
In case you want to proceed with installation without plug, proceed as described below:
- Use a screened cable with a minimum section of 0,5 mm
- Use a ground cable at least 20 mm longer than the active wires.
- Connect the ground connection wires to the corresponding terminal.
- Pull the wires to make sure they are connected correctly, then stop them with the specific cable tie.
For correct dimensioning of the guards, please refer to voltage and current consumption indicated on the
label located on the unit.
To access the board, remove the screws (12a) and the panel (12b) of the terminal box (12) (Fig.11).
The appliance connection MUST respect the European and national standards and MUST be
protected by a 30 mA differential switch.
