Installation Rules Notes and Warnings
Protect the device from direct exposure to sunlight.
Do not position the device near or directly in contact with sources of heat or
electromagnetic fields.
Fix the device of a height of at least 60 cm from the ground.
In a clearly visible place easily accessible.
Connect the device to power lines other than those for operating motors or other
large power devices which could generate network interference or instability.
The electrical supply of the unit must be protected by a differential switch 230Vac~
30mA and a bipolar magneto thermic 230Vac~ 10A, positioned in a place easily
accessible.
Before working on the equipment to perform any operation switch off the
magneto thermic differential switch.
For electric operations, always remove voltage, wait 30 seconds for the
inside capacitors to discharge before opening. At the end of the operations,
close the device to restore the correct degree of protection before powering up.
For the connection of the supply voltage, use anti-flame wires with a minimum
section of 0.75mm² certified and conform to the standard IEC60227 or IEC60245.
Use flame-retardant cables with a minimum cross-section area of 0.75 mm² for all
control signals.
Use flame-retardant cables with a minimum cross-section area of 0.75 mm² to
connect to the indicating relays.
Use flame-retardant cables with a minimum cross-section area of 0.5 mm² for
electro valves control signals.
The wire ground conductor of protection must be yellow/green.
The wire ground conductor of protection must be connected first.
The wire which is colored yellow/green must only be used for the ground conductor.
