5. Maintenance
Warning!
Electric shock hazard!
• Do not carry out any maintenance or repair work without first switching
off the high voltage generator and disconnecting the supply voltage.
• The machine which has the units fitted must not be in operation.
• Repairs and maintenance work must be carried out by qualified person-
nel only.
5.1 High voltage generator
The generator must be checked regularly to ensure its proper functioning.
The cooling fins must be kept clean and the connections of the high volt-
age cables must be free of dirt and other foreign matter. The intervals for
the check depend on the application and must hence be defined by the
user according to the operating conditions. The generator itself does not
require any maintenance.
5.2 Charging bars
To ensure the proper function of the charging bars, clean weekly with
compressed air free of oil and water (max. 6 bar) and a brush with soft
plastic bristles.
Remove encrusted dirt (e.g. grease, adhesive, ink, etc.) from the charging
bars with cleaning gasoline or a similar solvent. Do not immerse bars and
the high voltage cable in solvent!
Warning!
Risk of deflagration!
Wait until the solvent has evaporated before restarting the generator.
Caution!
Do not damage the emission tips of the charging bars.
