ELECTRICAL WIRING

Diameters of 0.5 mm² to 1.5 mm² are sufficient for the connecting cables owing to the low current values applied.

In any case the section must prevent the current density from exceeding 4 A/mm² in each conductor. The cross-section

of the conductors must also be adequate in relation to the lenght of the cable used to avoid a drop in the voltage

along the cable over the values prescribed by the regulations on the subject.

One of the conductors is solely used for the earthing of the capacitive

level gauge PFG-06. It is likewise recommended 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 the directive 2014/34/EU

Category 2 and EN 60079-31.

CAUTION :

In the terminal board compartment, the connection for

Faston type cable terminal whose position is marked by the symbol

on the printed circuit (Fig. 1) is used for the earthing of the level gauge.

The yellow-green conductor (only green for the USA) of the power cable

must be connected to this terminal.

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.

Inside the cover there is the wiring plate (Fig. 2) which has printed on it the wiring diagram for the power supply and

use of the level gauge.

DECLARATION OF CONFORMITY

Always check that the mains voltage and

frequency correspond to those given on the

plate of the level gauge before powering it.

The power cable must be fixed to the main by

a qualified installer in compliance with the

current safety standards in merit.

For electric connections to the terminal use

Faston cable terminals ( 6.3 x 0.8 mm. ).
