4. The supplied grounding cable (green / yellow) must be
connected to the grounding screw of the electrostatic
manual powder coating equipment. The grounding cable
must have good metallic connection with the coating
enclosure, the recovery unit and the conveyor chain
respectively. Any suspended objects must be connected
to the true earth ground. The provided powder hose
must be used as it provides ground to the applicator.
5. The voltage and powder feed lines to the powder
applicators must be protected against mechanical,
thermal and chemical damage.
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. The booth air must be interlocked with the controller of
the powder applicator. If the booth is switched off the
controller is off.
8. The powder spray applicator may only be operated in
a powder spray enclosure with industrial ventilation.
Operation creates a hazard zone around the powder
spray applicator. (Reference EN 16985: 2018 NFPA-33)
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/m3(must meet requirements
of EN 12981).
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 applicator 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 ammable cleaners, the powder
spraying device must be turned off, separated from the
power supply, secured against reconnection and allowed
to discharge to true earth ground.
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 powder
applicator 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 Powder may be used or
warranty and agency approval are voided.
