When working with solvent-based paints, a conductive connection (potential equalization
cable) must be established between the original container and the device.
When working with water-based paints, all components conveying product must be
isolated.
In particular, ensure that all components have the same potential in order to minimize
high voltage problems.
Ground all device components.
Ground the work pieces to be coated.
A poorly grounded work piece causes:
very bad wrap around
uneven coating
back spraying to the high-speed rotary atomizer, i.e. contamination
Prerequisites for perfect grounding and coating are:
clean suspension for the workpiece to be coated
grounding of spray booth, conveyor system and suspension equipment on the
building side in accordance with the operating manuals or the manufacturer's
information
grounding of all conductive parts within the working area
the grounding resistance of the work piece must not exceed 1
(megohm)
only connect high-voltage generator and/or ground switch to signal ground (e.g.
water pipe)
