Zone and Machine Classification according to ATEX
This machine is classified as equipment group II, equipment category 2G, type of protection Ex h, eligi-
ble for gases of explosion group IIB, equipment protection level Gb and can be used in zone 1.
See also type plate:
II 2G Ex h IIB T6 Gb
In accordance with legal requirements, the ATEX zone definition around the machine and creation of
an explosion protection document comes under the responsibility of the "responsible person of the
company" where the machine is placed as this classification is subject to the cleaning fluid used and
various conditions such as ventilation.
However, at this point the operator should be supported with general advice to comply with this ob-
ligation. Helpful advice can also be found in EN 12921‐1 and ‐3 and EN ISO 80079-36.
If using the machine with flammable cleaning fluids, the following zone designation has to be consid-
ered:
Zone 1
→
The interior of the machine
Zone 2
→
Surroundings within 1.0 m
Mark the different zones with appropriate warning and prohibition signs. Markings on the floor can be
helpful. In the area surrounding the machine, open flames and other ignition sources (e.g. welding or
grinding equipment) are not allowed. In addition, smoking is prohibited. Temporary work causing igni-
tion sources must be approved in writing and appropriate additional safety measures must be applied
(e.g. remove all combustible materials; firefighting equipment must be on hand in the working area.)

Requirements for the Installation Site
Horizontal industrial floor with electrical resistance of max. 10
8
Ohm.
Dry and protected from frost.
Very good technical room ventilation with at least 5 air changes per hour (Depending on local
regulations).
Do not install or operate the machine within a radius of 1.5 m from heat sources.
Ensure an ambient temperature of 5 °C – 40 °C and do not expose the machine to direct sun-
light, as this carries a risk of overheating.
Follow the relevant legislative and regulatory safety instructions regarding substances hazard-
ous to water applicable in the country where the machine is installed.
Follow the safety regulations according to zone designation.
The machine can be placed against the wall or in a corner. A 1.5 m space should be provided
in front of the machine.
Requirement in German DGUV (German Social Accident Insurance) Information 209-046:
“In rooms with filling, mixing and pumping of flammable liquids you must have at least 5 air
changes per hour. Therefore, a technical room ventilation system is required. The air-outlet
opening must be near the ground. Air-inlet and –outlet must be placed in a way that a com-
plete and even air exchange is achieved”
