SECURITY INSTRUCTIONS
1.
For mains input and DC outputs + alarms, use separate holes on the bottom of the box to pass the cables. Furthermore, the
material of the joint pipe/box must have a flammability class V-1 or better
2.
The relay contact "GUASTO" and "RETE" must be connected only to circuits operating with SELV Voltage.
3.
For AC supplying, provide a 6A protection bi-pole magneto-dynamic switch, easy to access
4.
The wires must have a section of 1,5mm and be equipped with adequate buttonholes where they are subject to pressure
contact.
5.
The installation of the power supply must be carried out by qualified personnel aware of the security norms EN60950 and
concerning power supplies CEI-64-8.
INSTALLATION
Mechanical mounting
This device has to be mounted on vertical stable walls, suitable to support the power supply, by means of 4 screws with 6mm diameter,
for spacers and screws on the 4 holes on the bottom of the box. The battery must be fixed using the strap given within.
