GROUNDING

For security reasons the manual system must be properly grounded. Normally this is done
via the mains cable.
Good grounding of the work piece is also necessary for optimum powder coating.
It is important to keep the ground cables as short as possible. Ground cables of an excessive
length must be shortened. Ground cables of an excessive length must never be wound up
on a roller.
A poorly grounded work piece causes:
– dangerous electric charging of the work piece,
– very poor wrap-around,
– uneven coating,
– back spraying to the spray gun, i.e., contamination.
Prerequisites for perfect grounding and coating of a work piece are:
– clean suspension of the work piece to be coated,
– The grounding resistance of the work piece must not exceed 1 M .
(Resistance to ground measured at 500 V 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 heavy radio frequency interference (EMC).
