17. Attach the cover to the mains output terminal from the control unit.
18. Connect the control unit's grounding cable with the signal ground!
19. Connect compressed air from the compressed air network of the company to the
manual system.
20. Connect the mains cable to the control unit and plug it into the socket.
6.5 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 bad wrap-around
– uneven coating
– back spraying to the spray gun, i.e., contamination
Prerequisites for perfect grounding and coating of a work piece are:
– Electroconductive suspension for the work piece that is to be coated
– Regular cleaning of powder residue from hanger
– Grounding of the spray booth, conveyor system and suspension equipment on site, in
accordance with the operating manual or the manufacturer's information
– Grounding cable connected to the control module or control cabinet
– That a grounding resistance of the work piece of 1 MΩ is not exceeded
(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 sufficiently cleaned and therefore the work pieces are not sufficiently
grounded! These sparks can cause heavy radio frequency interference (EMC).
