• An overcurrent protection device with a nominal current rating

16 A
and breaking capacity

4 kA must be installed in the mains power sup-
ply circuit. To ensure that no voltage is supplied to the bars when the
material web is at rest, enabling the supply voltage to the power supply
via machine contact is recommended. If the material web is at rest, or if
the machine is not in operation, no high voltage is supplied to the bars
in this case (see
chapter 3.6 "Connecting supply voltage”, page 14 ).
• Before starting up the power supply the user must make sure that the
power supply and the bars have been installed and assembled cor-
rectly. The supply voltage can then be switched on (see
chapter 4.1
"Startup”, page 16 ).
• The power supply must be checked regularly to ensure its proper func-
tioning. The connections of the high voltage cables must be free of dirt
and other foreign matter (see
chapter 5.1 "Power supply”, page 17 ).
• Make sure that the bars are clean at all times. Dirt results in malfunc-
tions and in premature wear of the units.
• When cleaning do not soak the bars and the high voltage cable in sol-
vent and do not damage the emission tips; allow the solvent to evapo-
rate completely before restarting the unit (see
chapter 5.2 "Discharging
bars”, page 17 , chapter 6 "Trouble-shooting”, page 18 ).
• Ex-Warning:

Only fuses specified in the spare parts list and complying with Standard
IEC 60127-2/5 may be used; failure to observe this specification will
void the Ex approval (see
chapter 6 "Trouble-shooting”, page 18 ).
• Potential risk for wearers of cardiac pacemakers:

Moving the chest closer than 3.5 cm to the emission tips of the
discharging bars or making surface contact with several emission tips
(touching a single tip is not critical) can result in a temporary switchover
of the cardiac pacemaker into the fault mode. Permanent proximity or
contact can therefore cause severe problems.

If it is likely that the chest of such a person comes closer than 3.5 cm to
the emission tips of the discharging bar, or if several emission tips are
touched at the same time, the appropriate warning notices must be
displayed.
• 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 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
