DANGER
WARNING
CAUTION
may only be commissioned after it has been installed in the machine/system for
which it is intended.
Use is permitted only under the operating conditions and within the performance
limits listed in the technical data. Only use compressed air as the medium.
The product is technical equipment and is intended for professional use only.
Intended use includes having fully read and understood these instructions, espe-
cially chapter g 2. Safety instructions.

2.2 ATEX

If operated as intended, mechanical maintenance units/equipment have no
inherent potential source of ignition and no internal explosive atmosphere.
They are not labelled according to ATEX Directive 2014/34/EU. Manufacturer
declarations may be requested via your service partner.
It is imperative that you comply with the set-up regulations for ex compo-
nents (e.g. EN 1127-1, EN 60079-14).

2.3 Use of maintenance unit/equipment

• ln Zone 1 (gas-ex, category 2G) in explosion groups IIA, IIB and IIC
• ln Zone 2 (gas-ex, category 3G) in explosion groups IIA, IIB and IIC
• ln Zone 21 (dust-ex, category 2D) in explosion groups IIIA and IIIB
• ln Zone 22 (dust-ex, category 3D) in explosion groups IIIA and IIIB

2.4 Permissible zone

When combining electrical equipment and mechanical components without any
inherent source(s) of ignition, identification of the electrical equipment must al-
ways be taken into account when selecting the zone. Only accessories compliant
with all statutory European and national regulations may be used in explosive ar-
eas.
• The set-up regulations in the country of use must be observed.
• The devices may be subject to electrostatic charging. Appropriate measures
must be adopted to exclude any risk, including electrostatic grounding, "Only
clean with a damp cloth" and avoidance of charging processes.
– When used in gas ex-areas, a "Only clean with a damp cloth" warning sign
must be mounted.
– A warning label is mounted on various pieces of equipment as an example.
• All external materials consist of suitable low-sparking materials and light-
weight metal. However, the operator is solely responsible for checking igni-
tion danger caused by sparks during operation of the entire machine.
• On some versions the outer material is aluminum. These versions must be
protected against external impact energy.
• The mechanical components in the series must be included in the potential
equalization.
• If the maintenance unit/equipment has built-in electrical components/
• devices, such as solenoids etc., the electrical part of the
• maintenance unit/equipment is subject to ATEX Directive 2014/34/EU with all
its
• consequences (name plate, ATEX identification etc.). The operating instruc-
tions of the electrical device must be observed.
• Repairs and/or changes to maintenance units/equipment
• operated in explosive areas are not permitted.
• In explosion group IIC and Zone 1 external parts must not have any projecting
2
surfaces in plastic > 20 cm ; for IIB or dust 100 cm
must not be used where high electrostatic charging is likely to be caused
(propagating bush discharges) (not possible with human body static).
– Do not blow off/clean the maintenance unit/equipment with compressed
air.
• Only insulated connection tubing with a diameter < 20 mm (IIC) or < 30 mm
(IIA, IIB, dust) may be used.
• Compressed air may only be discharged diffusely in ex areas.
• Dust deposits must be removed regularly.
• If the housing leaks, you must stop using the equipment.
• Compressed air generation and preparation must take place outside the ex
area.
• Use of combustible or explosive media is not permissible.
• Stray current (e.g. in systems with electrical corrosion protection) must not be
carried over components.
• EN 1127-1 Appendix A must be observed in case of assembly in ex areas (if
necessary, use low spark tools).
