1.6.- Built features
1.6.1.- General information
The meter has an insulating enclosure with class II protection and double insulation.
As specified in the directives 2002/96/CE and 2002/95/CE, none of the materials or
substances listed in them are used. The materials used are fire retardant, halogen free and
with low emissions of opaque, toxic or corrosive fumes. The running of the equipment is not
affected by the presence of external magnetic fields.
The meter manufacturer certifies that, at a temperature of 35ºC, the device will have a
minimum service life of 20 years.
1.6.2.- Environmental characteristics
The meter provides:
Protection levels provided by the enclosures, Code IP51, CEI 60529:2001 standard.
Protection against salt mist, standard UNE-EN 60068-2-11:2000.
Resistance against ultraviolet rays, standard UNE-EN 60068-2-5:2000.
1.6.3.- Voltage connection
The jumper internally separates the voltage and current circuits, making it impossible to
manipulate them externally.
In the indirect and semi-indirect connection models, the voltage and current circuits are
separated galvanically.
1.6.4.- Seals
The cover and the lower slot of the meter are closed, it being impossible to open or insert
foreign objects without breaking the enclosure. In addition, the device is equipped with all the
regulation seals: on the meter cover, the sealable button and the wire cover.
