•
Ambient temperature: - 5 ° C ... + 40 °C
•
Storage temperature: - 10 °C ... + 50 °C
•
Relative humidity: 10 % ... 95 % (without condensation)
5.1 Earthing
The earthing system must be performed in conformity with CEI and ISPELS rules or rules valid in the country
where the panel is installed.
In any case, must have a resistance lower than 10 Ohm (measured with disconnected devices). This complies
the CEI 68-12 standard for TN installations.
The earth connection to the control unit is compulsory and it must be performed on the CNAL terminal block.
(refer to basic board).
5.2 Main power supply
The control unit is powered by the mains voltage and, in case of mains breakdown it can continue to normally
operate due to the re-chargeable batteries contained in the same control unit.
The required features for the mains supply are:
•
Voltage: 100 ... 240 V AC
•
Frequency: 50 / 60 Hz
•
Current: max. 1.2 A @ 230 V AC
Particular care must be taken when the installation is performed near powerful electromagnetic
sources (ex. repeaters, radio relays, motors, etc.).
5.3 Power supply
The internal power supply has the following output: 28,8
(Power supply for control unit, user output, external load power supply).
User Output: 28,5

Number of batteries that can be connected = 2 x 12 V / min. 7 Ah, max. 12 Ah
•
The battery charger section has the following signalling thresholds
Exhausted battery threshold = 21,5 V DC
Re-charge Fault threshold = 3,4 V DC (voltage difference between the two batteries)
Battery release threshold = 19,5 V DC
Threshold of internal battery resistance =
5.4.1 Batteries
Average duration declared by the manufacturer is 3 ... 5 years at an ambient temperature of + 20 °C.
