• In any case, following installation, check the tightness of the plant;
• Wiring cannot have cables connected directly to the coil. ALWAYS and ONLY use the connector identified by the
manufacturer;
• Before wiring the connector (1), unscrew and remove the central screw (16). Use the special cable terminals (see the figure
below). NOTE: Connector wiring (1) needs to be carried out taking care to ensure the product's IP65 rating;
• Wire the connector (1) with a 3x0.75mm² cable having an external Ø from 6.2 to 8.1 mm. The cable must have double sheathing,
suitable for outdoor use, with a minimum voltage of 500V and a temperature of at least 105°C;
• Connect terminals 1 and 2 to the power supply and the earth cable to terminal ;
• IMPORTANT: with 12 and 24 Vdc power supplies it is necessary to observe the polarity;
• Secure the connector (1) to the coil (11), tightening (recommended tightening torque 0.4 N.m ± 10%) the centre screw (16);
• The valve needs to be earthed either through the pipe or through other means (e.g. cable jumpers).
