2 Safety Regulations
Paragraph 0, Point 01 of EN 50176:2009 is applicable to the elds of application of the apparatus.
This Standard also denes the design requirements for safe operation of the apparatus and the
electrical installation, including the forced ventilation.
The constructional requirements for the spray booth, dened in Standard EN 12215:2005, are also
applicable. This applies particularly to the identication of explosion hazardous areas.
This stipulates that the apparatus may only be used in areas where forced ventilation ensures that
during
• the application of ammable liquid coating materials, the average concentration of solvents
in the form of ammable vapour remains below 50% of the lower explosion limit (LEL) (EN
50176:2009, Para. 5.2).
Pursuant to EN 50176:2009, Para. 5.1.2/5.1.3, the apparatus is classied as a spraying system
type C-L or D-L when operated with electrostatic application equipment. This depends on the type
of installation and the local conditions.
In accordance with Para. 5.2.8 of EN 50176:2009, type C-L or D-L spraying systems must be tted
with a locally applied extinguishing system which may also be operated manually.
Section 5.2 of EN 50176:2009 must be observed. The requirements under 5.3 of EN 50176:2009
must be observed, in addition, if the apparatus is used as a 2G apparatus.
2.3 Electrostatic automatic spray gun
This electrostatic automatic spray gun meets the requirements of EN 50176:2009 – Stationary
electrostatic application equipment for ignitable liquid coating material – Safety requirements.
This Operating Manual deals only with the dangers typically associated with the automatic coat-
ing process when electrostatic spray guns in the described form are used under the conditions as
specied by the manufacturer.
These electrostatic spray guns are classied as Group II, Category 2 equipment pursuant to Di-
rective 94/9/EC, intended for use in explosive atmospheres generated by their own spray cloud.
Equipment in this category is intended for use in areas where an explosive atmosphere comprising
of gases, vapours, mist or dust/air mixtures may on occasion be expected.
