DANGER
Discharge of electrostatically charged components in atmospheres containing
solvents!
Explosion hazard from electrostatic sparks or flames.
Ground all device components.
Ground the work pieces to be coated.
Observe the minimum distance between the atomizer bell, the grounded unit
components and the work pieces to be coated. The minimum distance is 200 mm;
7.87 inch.

The distance between the work pieces and the parts of the spray system under high voltage
must be large enough to prevent a sparkover during normal operation. A minimum distance
of 200 mm; 7.87 inch is recommended in the area of the atomizer bell and cylindrical cover.
If required by the application or if demanded by the design, these distances can also be
shorter. In this case it is necessary to check that sparkovers do not occur.
Failure to observe the distances may result in high-voltage sparkover, damage and greater
contamination.
The distance between the bell plate and work piece to be coated should be selected with
care.
High voltages increase the risk of electric sparkover. Minimum distances can be found in
the following table.
