4 GENERAL SAFETY INSTRUCTIONS
4.1 SAFETY INSTRUCTIONS FOR THE OPERATOR
4.1.1 ELECTRICAL DEVICES AND EQUIPMENT
4.1.2 PERSONNEL QUALIFICATIONS
4.1.3 SAFE WORK ENVIRONMENT
To be provided in accordance with the local safety requirements with regard to the
operating mode and ambient in uences.
May only be maintained by skilled electricians.
Must be operated in accordance with the safety regulations and electrotechnical
regulations.
Must be repaired immediately in the event of problems.
Must be decommissioned if they pose a hazard.
Must be de-energized before work is commenced on active parts.
Secure the device against being switched back on without authorization. Inform sta
about planned work.
Observe electrical safety regulations.
The oor in the working area must be electrostatically conductive (measurements according
to EN 1081).
Make sure that all persons within the working area are wearing electrostatic-conductive
shoes.
Ensure that gloves worn are made of conductive material.
The powder release must be electrically interlocked with the powder spray system's
exhaust air equipment.
Excess coating product (overspray) must be collected up safely.
Ensure that there are no ignition sources such as naked ames, sparks, glowing wires,
or hot surfaces in the vicinity. No smoking.
Maintain su cient quantities of suitable re extinguishers and ensure that they are
serviceable.
The operating company must ensure that an average concentration of powder lacquer
in the air does not exceed 50% of the lower explosion limit (LEL = max. permitted
concentration of powder to air). If no reliable LEL value is available, the average
concentration must not exceed 10 g/m³.
Keep this operating manual at hand near the device at all times.
Always follow local regulations concerning occupational safety and accident prevention.
Ensure that the device is operated, maintained and repaired only by trained persons.

4.2.1 SAFE HANDLING OF WAGNER POWDER SPRAY DEVICES
4.2.2 GROUNDING THE DEVICE
4.2.3 PRODUCT HOSES
4.2 SAFETY INSTRUCTIONS FOR STAFF
Use only an original WAGNER powder hose.
Always follow the information in this manual, particularly the general safety instructions
and the warning instructions.
Always follow local regulations concerning occupational safety and accident prevention.
Under no circumstances may anyone tted with active implants (e.g., a pacemaker)
enter the area where the high-voltage eld between the spray gun and the work piece
to be coated builds up!
Do not point spray guns at people.
Before all work on the device, in the event of work interruptions and functional faults:
– Switch o the energy/compressed air supply.
– Secure the spray gun against actuation.
– Relieve pressure on spray gun and device.
– In case of functional faults: Identify and correct the problem, proceed as described in
the "Fault Recti cation" chapter.
The electrostatic charge may, in certain cases, give rise to electrostatic charges on the
device. This may result in the formation of sparks or ames when discharging.
Ensure that the device is grounded before each coating process.
Ground the work pieces to be coated.
Ensure that all persons inside the working area are grounded, e.g., by wearing electrostatically
conductive shoes.
The functionality of grounding cables must be checked regularly (see EN 60204).

4.2.5 HANDLING POWDER LACQUERS
When preparing or processing the powder and cleaning the device, take note of the
processing regulations laid down by the manufacturer of the powder lacquers being
used.
Take note of the manufacturer’s instructions and the relevant environmental protection
regulations when disposing of powder lacquers.
Implement the prescribed safety measures, in particular the wearing of safety glasses
and safety clothing as well as the use of protective hand cream.
Use a mask or breathing apparatus if necessary.
To ensure su cient protection of health and the environment, only operate the device
in a powder booth or on a spray wall with activated ventilation (exhaust air).
4.2.4 CLEANING
Before starting cleaning or any other manual work, the high voltage in the spray area
must be shut down and locked to prevent it from being switched back on.
Lock the compressed air supply and decompress the device.
Secure the device against being switched back on without authorization.
Use only electrically conducting and grounded tanks for cleaning uids.
Preference should be given to non- ammable cleaning uids.
Flammable cleaning liquids may only be used if, after switching o the high voltage, all
high-voltage conducting parts are discharged to a discharge energy of less than 0.24 mJ
before they can be accessed.
Most ammable solvents have an ignition energy of around 0.24 mJ or 60 nC.
The cleaning agent's ash point must be at least 15 K above the ambient temperature.
Only mobile industrial vacuum cleaners of design 1 (see EN 60335-2) may be used to
remove dust deposits.
