GROUNDING

For safety reasons the system must be properly grounded. WAGNER recommends the use
of a copper cable of at least 16 mm² with suffi cient mechanical resistance for connection
to the signal ground.
Good grounding of the work piece is also necessary for optimum powder coating.
A poorly grounded work piece causes:
dangerous electric charging of the work piece,
very poor wrap-around,
uneven coating,
back spraying to the gun, i.e., contamination
Prerequisites for perfect grounding and coating are:
Conducting suspension for the work piece that is to be coated.
Grounding of the powder coating booth, transport and suspension equipment to
be provided on site in accordance with the corresponding operating manuals or the
defi nitions laid down by the manufacturer.
Regular cleaning of hangers from powder residues.
Grounding resistance for the work piece of a maximum of 1 MΩ (megaohm).
Grounding cable connected to the controller module or control cabinet.
Sparks between work piece and conveyor hooks (hangers) can occur if hooks or
other hanger parts are not completely cleaned! These sparks can cause heavy radio
frequency interference.
