the site of installation 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).
• Static on personnel
Static charges on personnel are unlikely if the bars are installed pro-
perly. Personnel must wear conductive footwear.
Please note all national regulations regarding electrostatic charge (e.g.
TRGS 727 in Germany).
2.4 Contact protection
The site of installation and/or use of the units is outside the control of
Eltex, contact protection against inadvertent contact of the bars and of live
components by personnel as specified by the employer’s liability insu-
rance association may have to be provided (e.g. DGUV V3 in Germany).
Contact protection devices made of conductive material must be
grounded.
2.5 Inspection of the protective resistors - contact protection
The function and the appearance of the protective resistors must be
inspected at regular intervals. The inspection intervals are specified in the
accident prevention regulations, as amended (e.g. in Germany DGUV
V3). Eltex recommend inspection intervals of 6 months.
The function of the series resistors must be checked using a suitable
measuring device. The test voltage must be 1,000V. The measured resis-
tance between the high-voltage connection and the individual emission tip
must not fall below 234 MOhm and not exceed 286 MOhm.
2.6 Technical advance
The manufacturer reserves the right to make changes to the technical
specifications without prior notice in order to adapt the units to state-of-
the-art engineering. Eltex will provide the latest information on any
changes or modifications in the operating instructions on request.
