ELECTRICAL WIRING
The conductors forming the power supply and signal carrying cable must have an adequate cross-section so that
the current density, in each conductor, is no higher than 4 A/mm². One of these is used only for the earthing of
the level gauge. The cross-section of the conductors must also be adequate in relation to the length of the cable
used to avoid a drop in voltage along the cable over the values prescribed by the regulations on the subject.
It is likewise reccomended to use flexible cables with an adequate outside diameter for the cable entries used
( not supplied ) to ensure a perfect seal of the cable clamp on the power supply and signal carrying cable.
Use exclusively cable entries certified according to directive 2014/34/EU, Category 2 and EN 60079-31.
CAUTION :
The terminal box contains a screw whose position is marked by the
symbol
made in the casting ( Fig.3 ) which has the function of making the ground
connection for the level gauge. This screw must be connected to the yellow-green
conductor ( only green for the USA ) of the power cable. The ground connection of
the level gauge, through the yellow-green conductor, is compulsory.
- The external earthing has to be carried out by the installator.
- The equipment has to be protected against impact and electrostatic inside the silo.
- The user has to protect the equipment circuits with fuses against short circuit.
- The max. surface temperature considered is without dust and not safety distance.
By the terminal box there is the wiring plate ( Fig.1 ) which has printed on it the
wiring diagram for the power supply and use of the level gauge. Always check
that the mains voltage and frequency correspond to those given on the plate of the level gauge before powering up.
