5. Maintenance
Warning!
Electric shock hazard!
• Switch off the generator 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.
• The bars passively absorb energy from the moving substrate web. The
high voltage cable must be plugged in or grounded to the generator. If
the high voltage cable is disconnected, the plug is live (high voltage)
and applies with full power on the plug; this may cause a spark dis-
charge and may lead to a risk of injury. Disconnected high voltage plugs
are not permitted or have to be grounded.
• Repairs and maintenance work must only be carried out by qualified
personnel.
To ensure the proper function of the charging bars, clean the bars at least
once a week using compressed air free of oil and water (max. 6 bar, com-
mercial pistol) and a brush with soft plastic bristles.
Clean grease, ink, glue, paper dust, etc. off the discharging bar using a
suitable solvent (benzine). Do not soak the bars and the high voltage
cable in solvent!
To maintain adequate insulation, insulating mounting material must be
cleaned at regular intervals.
Warning!
Risk of deflagration!
Allow the solvent to evaporate completely before restarting the unit.
Caution!
Do not damage the emission tips when cleaning the bars. Brush only in
longitudinal direction.
Caution!
No continuous sparking (electric arc) must be visible on the bar tips.
