6. The main power connection of the MS Powder coating
device must be electrically interlocked with the exhaust
system of the powder coating enclosure. The powder
coating device may only be switched on if the exhaust
air is running.
7. Set the exhaust system of the powder coating device
must also be switched off.
8. The powder spray gun may only be operated in a
powder spray enclosure with industrial ventilation.
Operation of the powder spray gun creates a hazard
zone around the powder spray gun.
9. The operator must ensure that an average concentration
of powder in the air does not exceed 50% of the lower
explosive limit (UEG=maximum permissible powder/
air concentration). If the UEG is not reliably known,
the mean UEG must not exceed 10g/m
3
(must meet
requirements of EN 12981, EN 16985).
10. The powder spraying equipment should be checked
annually by the operator for explosion protection.
11. The grounding of all conductive parts (hooks, chain
conveyors, etc.) must be checked at least weekly. The
Resistance to earth must be less than 1 MΩ (Mega
Ohm).
12. When cleaning the powder gun and when replacing
the nozzles, the controller must be switched off.
13. When working with cleaning agents that can develop
hazardous fumes, the manufacturer’s instructions must
be observed. Flammable cleaning agents should not
be used. Before using flammable cleaners, the powder
spraying device must be turned off, separated from
the power supply, secured against reconnection and
allowed to discharge to less than .24mJ.
14. Powder must be used according to the manufacturer’s
instructions.
15. When disposing of powder and cleaning agents,
manufacturer’s instructions and the applicable
environmental protection regulations must be observed.
16. In the case of damage (broken parts, cracks, etc), these
components should be removed and the automatic
powder gun no longer operated.
17. Repairs may not under any circumstances be carried
out in a hazardous area. Repairs must be performed by
authorized service centers from MS Powder. Only original
spare and wear parts from MS Oberflächentechnik may
be used.
NOTICE ON HARMLESS
DISCHARGES
When the high voltage is switched on, a glow or corona
discharge occurs at the tip. This is only visible in a dark
environment. When the electrode is near the grounded work
piece, this physical phenomenon can be observed. This
glowing discharge does not cause any ignition and does
not affect the functioning of the system. When the electrode
approaches the work piece, the controller automatically
reduces the high voltage to a safe value or, depending on
the setting, switches the high voltage off.
Touching the plastic parts of the automatic powder gun
with your finger can cause harmless discharges called
brush discharges. These discharges on the plastic parts
are caused by the high voltage field of the gun. However,
they have no ignition energy.
SAFETY CONSIDERATIONS
Any person who is responsible for the installation,
commissioning, operation, maintenance and repair of
powder spraying device must have read and understood
the operating instructions and particularly the "Safety"
section. The user company must ensure that the user
has the necessary professional knowledge to deal with
