kept clean (see chapter 3.6 "Connecting the high voltage cable of the
charging bar to the high voltage generator POWER CHARGER PC_ _”,
page 18).
• The operating voltages of the charging bars are different. Make sure
that the correct distance between the charging bar and the material sur-
face is maintained (see chapter 4 "Operation”, page 20).
• The current must not be allowed to exceed 1 mA per meter of active
charging bar length. The minimum operating current for any stable-cur-
rent working point must be >0.5 mA (see chapter 4.1 "Operating voltage
for the R130A / R130A3L / R131A / EXR130A / EXR130A3L charging
bars”, page 20, chapter 4.2 "Operating modes”, page 20).
• When cleaning the bars do not soak the bars and the high voltage cable
in solvent and do not damage the emission tips; allow the solvent to
evaporate completely before restarting the unit. No continuous sparking
(electric arc) must be visible on the bar tips (see chapter 5 "Mainte-
nance”, page 21).
• Check the units and the high voltage cables at regular intervals and
before startup for any damage. Any damaged components must be
repaired or replaced professionally before continuing to operate the
unit, or the units must be disabled.
• Make sure that the units are clean at all times.
Dirt results in malfunctions and in premature wear of the units.
• Do not touch the emission tips - risk of injury.
If the high voltage supply is connected, reflex responses to electrical irri-
tation can lead to secondary accidents; the charging bar as such is safe
to touch. If contact is made, the energy transferred is so low
(≤ 20 tips) that there is no risk of injury.
• Potential dangers for persons with cardiac pacemakers
The contact of several emission tips with the hand can trigger or sup-
press a single impulse. Such a single influence is irrelevant. A repeated
contact during a short period can be excluded because the electrical irri-
tation causes a warning effect. The charging bar as such is safe to
touch. If contact is made, the energy transferred is so low that there is
no risk of injury.
• If electrically conductive substrates or substrates coated with conduc-
tive material (e.g. metal foil or metal composites) are used (e. g. in the
printing process), the charging voltage must be disabled (in these prin-
ting units), if applicable the supply voltage of the generator must also be
disabled.
• The operation of the bars can generate ozone. The ozone concentration
levels developing near the bars depend on many different factors such
as site of installation, bar current and voltage, air circulation, etc., and
can therefore not be specified in general terms.
If the maximum allowable concentration of ozone must be observed at
