2.3 Work and operational safety
Warning!
Carefully observe the following notes!
• Before carrying out repairs, cleaning or maintenance work and before
resetting the unit after malfunctions, switch off the power supply and
disconnect the supply voltage.
• Any work involving the units and the discharging bars must be carried
out by qualified personnel.
• The bars passively absorb energy from the moving substrate web. The
high voltage cable must be plugged in or grounded to the power supply.
An unconnected grounding cable may cause a spark discharge and
may lead to a risk of injury.
• Check the discharging bars and the high voltage cables at regular inter-
vals for any damage. Damaged components must be repaired or
replaced before continuing to operate the unit, or the bar or cable must
be disabled.
• Keep the bars clean at all times.
• Do not touch the emission tips - risk of injury!
If the high voltage supply is connected, reflex responses to electrical
irritation may increase the risk of secondery accidents, especially in the
vicinity of unguarded rotating assemblies. 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.
• Potential risk for wearers of cardiac pacemakers:
If persons with a cardiac pacemaker approach or contact the bar, a
malfunction of the pacemaker cannot be ruled out; affix the appropriate
warning sign.
• Mechanical or electrical modifications of the discharging bars are not
permitted. Shortening the shielded high voltage cable on the connect-
ing side of the power supply is permitted. Extending the cable is permit-
ted only when using the Eltex distributor as well as original high voltage
cables and glands.
• The operation of the bars can generate ozone. The ozone concentra-
tion 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 the site of instal-
lation of the bar, the concentration must be measured on site.
The AGW value (maximum admissible concentration) serves to assess
the ozone concentration at the workplace. The user must make sure
that the appropriate national AGW value is at no times exceeded, e.g.
in Germany the ozone concentration occurring during the operation of
the system must not exceed the recommended value based on interna-
tional limits of 0.06 ml/m³ (0.12 mg/m³).
