nelle viti/bulloni di montaggio.
4) Verificare annualmente la sicurezza dei pressacavo.
5) Verificare annualmente l'eventuale presenza di danni alla scatola.
6) In aree con la presenza di polveri combustibili sarà necessario pulire
periodicamente la superficie superiore della scatola, limitando la
profondità dello strato a meno di 5 mm.
4.2 Resistenza agli agenti chimici
Prendere in considerazione l'ambiente d'utilizzo delle scatole per
determinare l'idoneità dei relativi materiali a sopportare l'azione di agenti
corrosivi eventualmente presenti.
4.3 Smaltimento

1 Safety rules
Junction boxes type ZENITH-P are designed as Group II Category 2
equipment and is suitable for use for fixed installation in areas with
explosion hazard designated Zone 1 / Zone 2 and Zones 21 / Zone 22.
These operating instructions must be kept in safe place for later
consultation. During operation, do not leave this instruction manual or
other objects in the enclosure.
Operate the enclosures type ZENITH-P only for their intended duty in the
undamaged and clean condition, and only where the resistance of the
material to the surroundings is assured.
The enclosures are designed to withstand an impact of 7 J, and to be used
in normal conditions of vibration. They are not designed for use in areas
subject to intentional or extreme conditions of vibration.
Enclosures are made of carbon loaded glass reinforced polyester. The
enclosures have a surface resistance between 10
present a hazard from static electricity.
In the event of incorrect assembly, the type of protection will no longer
be assured.
Only genuine SCAME spare parts may be used for replacement.
No modifications are allowed to the enclosures that are not expressly
mentioned in this instruction manual.
