  Output Voltage = 27,5V. 
  Output Current= 1A ~ 100 mVpp max (with temperature compensation). 
  Batteries = 2 x 12V - 7Ah. 
Suggested Batteries : 
Yuasa type NP7-12 o NP7-12FR (UL94) Faston - Capacity (20 Hr) = 12 V  7Ah  
Dimensions = 151(b) x 65 (p) x 98 (h). 
Fiamm type FG20721 o FGV20721 (UL94) Faston - Capacity (20hr) = 12 V  7.2Ah  
Dimensions = 151(b) x 65 (p) x 98 (h). 
Yuasa type NP18-12B o NP7-12BFR (UL94) Screw  - Capacity (20hr) = 12 V  17,2Ah  
Dimensions = 181(b) x 77 (p) x 98 (h). 
Fiamm type FG21803 o FGV21803 (UL94) Screw  - Capacity (20hr) = 12 V 18 Ah  
       Dimensions = 181(b) x 77 (p) x 167 (h). 
 
  The followings are thresholds for faults indication on the Battery charger section: 
Battery exaust = 21,5 Vdc. 
Difference between batteries thresholds = 3,4Vdc  
Battery cut-out thresholds = 20Vdc. 
Current from battery in standby condition without mains (no 230 Vac): 180 mA (12 lines with End of Line 
resistor – no external loads – display OFF)  
Current from battery in Alarm condition without mains (no 230 Vac) : 320mA

Gound connection must be wired following CEI and  ISPELS rules (Italy) or equivalent for different country. 
In any case must ground circuit must have a resistance less than 10Ohm (measured at drain-well with 
equipment disconnected). The Earth connection on CNAL terminals is mandatory .

This panel must be supplied with mains . In case of Mains loss the panel can continue to be supplied by internal 
batteries for some time. Mains line required characteristics are: 
  Voltage : 230 Vac mono-phase + 10%  - 15%. 
  Frequency: 50 / 60 Hz. 
  Current from Mains: 0.45 Aac. 
 
Note: Pay particular attention to don’t install the panel near high power 
electromagnetic sources as Radio transmitters , electric motors and so on.
