SECURITY INSTRUCTION
1. Utilize different fairlead holes on the bottom of the box, to pass cables for tension input and dc
alarms. Moreover, materials for pipe/box fitting must have HB inflammability class or
better.
2.
“GUASTO” and “RETE RIT” relay contacts, must be connected only to circuits working with
SELV tension.
3. For AC power supply, use a differential magneto-termic bipolar protection switch, easily
accessible.
4. Conductors must have cross section suitable to tension and equipped with adequate cable
terminals on contact pressure points.
5.
Installation of unit must be executed by qualified personnel who Know security requirements
EN60950 and concerning power supply units CEI 64-8.
INSTALLATION
Mechanical mounting
This unit has to be installed on vertical solid walls able to support the power supply unit using 4 plugs
of 6 mm, 4 washers and screws coming out from the 4 holes on the bottom of the box.
Electrical connection
Connect unit to power 230 Vac through a differential magneto-termic bipolar switch to protect line
against short circuit and operator from current leakage.
IMPORTANT: Utilize separated fairlead and tubes for input ac power supply (230 Vac) and dc
o alarms (SELV).
