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 250 mm; 9.84 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.
The attachment point for the TOPFINISH Bell 1S is not grounded!
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.

Sparkovers may arise for reasons other than electric charges from the device itself. To
prevent sparkovers, conductive work clothes (conductive safety boots and gloves) must
also be worn.
