5. Maintenance
Warning!

Electric shock hazard!
• Switch the power supply off and disconnect the supply voltage before
carrying out any maintenance or repair work.
• The machine which has the units fitted must not be in operation.
• Any work involving the units must be carried out by qualified electrici-
ans.
Power supply
The power supply must be checked regularly to ensure its proper func-
tioning. The connections of the high voltage cables must be free of dirt
and other foreign matter. The intervals for the check depend on the appli-
cation and must hence be defined by the user according to the operating
conditions. The power supply itself does not require any maintenance.
Check for correct ground connection!
Discharging bars
To ensure the proper function of the discharging bars, clean the bars at
least once a week using compressed air (max. 6 x 10
5
Pa and standard
compressed air pistole) and a brush with soft plastic bristles. Refer to the
operating instructions for the bar used.
Dirt deposits settling on the bars (e.g. grease) must be cleaned off using a
suitable solvent (benzine). Do not soak the bars and the high voltage
cable in solvent!
Caution!

Risk of deflagration!

Allow the solvent to evaporate completely before restarting the unit.

Do not damage the emission tips of the bars.
