INFORMATION ABOUT 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 eff 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 eff 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 fi nger, harmless discharges may occur due to
the high-voltage fi eld around the spray gun (so-called brush discharges). However, these
do not contain any ignition energy.
