6.7 GROUNDING
For safety reasons, the spray gun and the work piece must be properly grounded. For the
spray gun, this is done via the grounding connection.
Perfect grounding of the work piece is also necessary to achieve an optimum powder
coating.
A poorly grounded work piece causes:
dangerous electric charging of the work piece,
very poor wrap-around,
uneven coating,
and back spraying to the spray gun, i.e. contamination.
Prerequisites for perfect grounding and coating are:
clean suspension of the work piece to be coated,
grounding of spraying booth, conveyor system and suspension on the part of
the building site in accordance with the operating manual or the manufacturer's
information,
and grounding of all conductive parts of the system.
The resistance to ground of every work piece's locating point must not exceed 1 MΩ
(megohm) (measurement voltage must be 500 or 1000 V).
Sparks between conveyor, conveyor hooks (hangers) and work piece can occur
if electric contact points between conveyor, conveyor hooks (hangers) and work
piece are not su ciently cleaned and therefore the work pieces are not su ciently
grounded!
These sparks can cause heavy radio frequency interference (EMC).
Heavy paint mist if grounding is insu cient!
Danger of poisoning.
Insu cient paint application quality.
Ground all device components.
Ground the work pieces to be coated.
