Low battery:
control tension lower than 22 Vdc
Battery ok:
tension included between 22 Vdc and 28,5 Vdc
Overcharged battery:
tension over 28,5 Vdc
Mains:
presence of line tension 230 Vac
Failure
:
Led of general failure, it activates in case of:
Absence of 230 Vac mains
Faulty fuse
Loss of battery charge
Low battery
Overcharged battery
Disconnected battery
Battery resistance > 1 ohm
The power supply has been certified using YUASA NP 17-12 batteries
Security Instructions
For mains input and DC o 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
The relay contact “GUASTO” and “RETE RIT ” must be connected only to circuits operating with SELV tension.
For AC supplying, provide a 6 A protection bi-pole magneto-dynamic switch, easy to access
The wires must have a section of 1,5 mm and be equipped with adequate buttonholes where they are subject to pressure
contact.
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.
IMPORTANT: In case of mains failure and general anomaly condition, a technical intervention should be carried out
within 48 hours to avoid the complete discharge of the battery.
INSTALLATION
MECHANICAL MOUNTING
This device has to be mounted on vertical stable walls, suitable to support the power supply, by means of 4 6 mm screws, for spacers
and screws on the 4 holes on the bottom of the box. The battery must be fixed using the strap given within.
ELECTRICAL CONNECTION
Connect the power supply unit to the mains 230 Vac by use of a differential magneto-thermic bipolar 6 A. switch (minimum distance
between contacts 3 mm) aimed to protect the line against possible short circuit and operator against current leakage.
IMPORTANT: use different cables-passes and pipes for ac supplying input (mains 230 Vac) and dc o alarms (SELV)

Checks and Adjustments
Controls are shown Below (P1 and P2) are adjusted at factory and
must in no way be altered by the operator.
Tampering of these controls automatically means the lost of the warranty.
P1 - Potentiometer for adjustment of the output tension
P2 - Potentiometer for adjustment of the output current limit.
