4.3 NOTE ON SAFE DISCHARGES
With the high-voltage switched on, a luminous or corona discharge occurs at the electrode
tip; this can only be seen in the dark. This physical e ect can be seen when the electrode
is brought near the grounded work piece. This luminous discharge does not involve any
ignition energy and has no e ect on system handling. When the electrode approaches the
work piece, the control unit automatically reduces the high-voltage to a safe value. If you
touch plastic parts of the spray gun with your nger, harmless discharges may occur due to
the high-voltage eld around the spray gun (so-called brush discharges). However, these
do not contain any ignition energy.
