7.4 Safety characteristics
This material conforms with the following directives:
2004/108/EC Electromagnetic Compatibility.
2002/96/EC Waste electrical and electronic equipment.
8 ADITIONAL INSTRUCTIONS FOR THE ATEX VERSION
This chapter only applies to equipment intended for use in explosive atmospheres.
These equipment conform with the directive 94/9/CE (Equipment and protective systems
intended for use in potentially explosive atmospheres) as is indicated in the EC-type
examination certificate LOM 09ATEX2087 X and in its marking.
Given that this instrument is group II, it is intended for use in places likely to become
endangered by explosive atmospheres, but not in mines.
The category is 1GD, that is, it is intended for use in areas in which explosive
atmospheres caused by mixtures of air and gases, vapours, mists or dust are present
continuously, for long periods or frequently.
8.1 Non metallic parts and impact risk
WARNING: POTENTIAL RISK OF ELECTROSTATIC CHARGE.
The front of the apparatus consists of a transparent plastic window in order to let the user
see the position of the pointer on the scale.
Since the danger of ignition by electrostatic discharge when rubbing this window can not
be avoided, the instrument must always be cleaned with a damp cloth.
WARNING: IMPACT RISK.
As the base of the apparatus is made in aluminium, the instrument must be always
installed and used in places with low impact risk.
8.2 Facilities connecting conductive parts to earth
When the instrument is not grounded securely through the connection process, it should
be grounded through the housing screw, as shown in the figure.
