CABLE REQUIREMENTS
Type of cable: 2-conductor TWISTED-SHIELDED cable.
Sections concerning the line total lenght (for the line STYLE 6", the operator must consider the loop lenght) which
CANNOT exceed 3000 meters and whose resistance must be lower than 40 Ohm.
Example:
•
Up to 500 mt. - cable 2 x 0.5 mm
2
•
Up to 1.000 mt. - cable2x1mm
2
•
Up to 1.500 mt. - cable 2 x 1.5 mm
2
•
Up to 2.000 mt. - cable2x2mm
2
•
Up to 2.500 mt. - cable 2 x 2.5 mm
2
•
Up to 3.000 mt. - cable2x3mm

As far as the laying of cables is concerned, follow the below listed instructions:
- Suitable pipes;
- The cables must run at a proper distance from the power lines and must not be in the vicinity of any High Voltage.
Troubles often may be caused by:
•
Air-conditioning installation
•
Engines or electric welding machines
•
Electrical furnaces and elevators
•
Radio links, etc.
ELECTRIC POWER
Power Supply Voltage: 220 V single phase +/- 10%.
Frequency: 50 Hz +/- 1 Hz.

NOTE
: pay special attention when installing the system near big electromagnetic sources (REPEATERS).
EARTH PLANT
The earth plant must be performed according to the CEI and ISPLES rules. The resistance CANNOT exceed
10 Ohm (to be measured at the well with disconnected mains).
