GROUNDING

Defective grounding will result in high levels of powder mist!
Danger of poisoning.
Insuffi cient paint application quality.
For safety reasons, the spray gun and the work piece must be properly grounded. For the
spray gun this done through the gun support.
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 bad wrap around
uneven coating
back-spray 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 by the customer in
accordance with the operating manual or the manufacturer's information.
Grounding of all conductive parts of the system.
The resistance to ground of every work piece's locating point must not exceed 1 MΩ
(megaohm) (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 suffi ciently cleaned and therefore the work pieces are not suffi ciently
grounded!
These sparks can cause severe radio frequency interference (electro-magnetic
compatibility = EMC).
ORDER NUMBER DOC 390829
WARNING
