5. CHARACTERISTICS WITH REGARDS TO SAFETY
Equipment conforms to the following directives and norms.
97/23/CE Pressure Equipment
73/23/EEC Low voltage.
89/336/EEC Electromagnetic compatibility
94/9/EC (ATEX) Equipment & protective systems intended for use in potentially explosive
atmospheres
EN 50014 Electrical apparatus for potentially explosive atmospheres. General
requirements.
EN 50018 Electrical apparatus for potentially explosive atmospheres. Flameproof
enclosures “d”.
EN 50281-1-1 Electrical apparatus for use in the presence of combustible dust. Part 1-1
electrical apparatus protected by enclosures.
This instrument, since it belongs to Group II, is destinated to be used in areas where there is a
hazard of explosive atmospheres forming, except for mining installations.
Since it is category 2G it can be used in ambients where there is a probability of formation of
explosive atmospheres due to gases, vapours, mists or powder in suspension.
IMPORTANT
•
The respective national regulations, as well as the general engineering rules that apply to the
installation and operation of apparatus in explosive atmospheres must be observed .
•
The end user is responsible for the safe use of this equipment.
•
Modification or reparation of the flameproof housing is not permitted.
•
The opening of the housing always shall be done without voltage. The housing is considered
to be closed when the lid is completely screwed down and the grub screw in its locking
position.
•
Only approved EExd IIC cable glands with the same thread as the housing should be used.
•
The flameproof seals of the housing should kept greased to avoid corrosion, water ingress
and seizing. Clean rests of grease and corrosion, do not use sharp objects that can damage
the surface of the seal, and grease using a chemically and thermally stable grease with a
drip point > 200ºC.
