Dear Customer,
The ES24 high voltage power supplies are power supply units for the ion
blower nozzles, ion blower heads and the series R45, R47, R5x and R6x
AC discharging bars.
The discharging bars and the ES24 power supply are used mainly in
cases where disruptive static charges on fast-moving material webs
impair production processes and need to be eliminated.
The ES24 power supply features the following characteristics:
• stable 5 kV AC output voltage
• output current monitoring
• short-circuit proof
• independent from different national line voltages
• connecting options for several consumer units
(bars, blowing nozzles) via ESVY61 or ESV61 high voltage distributor
(optional)
• protection class IP54
• compact design, small dimensions
• adaptable and easy to install
• low weight compared with conventional transformers
Please read the operating instructions carefully before starting the instru-
ment. This will help you prevent personal injuries and damage to property.
Please give us a call if you have any suggestions, proposals or ideas for
improvements. We greatly appreciate the feedback from the users of our
appliances.

2. Safety
The ES24 Power Supplies have been designed, built and tested using
state-of-the-art engineering, and have left the factory in a technically and
operationally safe condition. If used improperly, the units may neverthe-
less be hazardous to personnel and may cause injury or damage. Read
the operating instructions carefully and observe the safety instructions.
Always observe the rules and regulations applying in your country with
reference to opening and repairing electrical appliances.
The manufacturers will not assume any liability and warranty if the units
are used improperly or used outside the intended purpose.
2.1 Proper use
The ES24 Power Supplies may be operated only in connection with the
appropriate Eltex discharging bars for AC operation.
Modifications or changes made to the power supplies are not permitted.
Use only original Eltex spare parts and equipment.
2.2 Identification of risks and hazards
Possible risks and hazards resulting from the use of the power supplies
are referred to in these operating instructions by the following symbols:
Warning!
This symbol appearing in the operating instructions refers to operations
which, if carried out improperly, may result in serious personal injuries.
Caution!
This symbol appearing in the operating instructions refers to operations
which, if carried out improperly, may result in damage to property.
2.3 Work and operational safety
Warning!
Carefully observe the following notes and the complete chapter 2 "Safety”,
page 7!
• Before carrying out repairs, cleaning or maintenance work and before
resetting after malfunctions, switch off the power supply and disconnect
the mains supply voltage (see chapter 5 "Maintenance”, page 17, chap-
ter 6 "Troubleshooting”, page 18).
• Before carrying out any work involving the units, the machine which has
the units fitted must not be in operation (see chapter 5 "Maintenance”,
page 17, chapter 6 "Troubleshooting”, page 18).
8BA-en-2062-2106_ES24
• Any work involving the units must be carried out by qualified electrici-
ans (see chapter 5 "Maintenance”, page 17, chapter 6 "Troubleshoo-
ting”, page 18).
• The ES24 high voltage power supply must be operated only with a
24 VDC line voltage (see chapter 4 "Operation”, page 16).
• Before starting up the power supply the user must make sure that the
power supply and the bars have been installed and assembled
correctly. The supply voltage can then be switched on (see chapter 4
"Operation”, page 16).
• Before starting the unit make sure that the appliance is permanently
grounded via the grounding terminal (2, Fig. 1). The ground cable
should have a minimum cross section of 1.5 mm2(see chapter 3.2
"Ground connection”, page 12).
• Check the units, the electrical wiring and the hight voltage cable at
regular intervals and before startup for any damage. Any damaged
components must be repaired profesionally or replaced before conti-
nuing to operate the units, or the bar or cable must be disabled.
• Connect or disconnect the high voltage cable / the bars only with the
power supply switched off (see chapter 3.3 "Connecting the high vol-
tage cable”, page 12).
• In applications involving moving bar, the high voltage cable must be
attached such that there is no cable movement near the connection
zone of the consumer units (power supply, distributer or discharging
bar); see chapter 3.3 "Connecting the high voltage cable”, page 12).
• Both the lengths of the high voltage cable and of the active bars are
limited, observe maximum lengths (see chapter 3.5 "Maximum active
bar length and length of the high voltage cable”, page 14).
• Operating the ES24 power supply requires a 24 V DC line voltage
designed for a maximum current of 1.4 A (see chapter 3.6 "Connecting
supply voltage and fault signal contact”, page 15).
• The supply voltage 24 V DC at the universal plug must be connected to
Contact 2 (24 V) and Contact 3 (Ground), or plugged into the power
supply available as accessory.
Contact 3 (Ground) must be connected to the ground (see chapter 3.6
"Connecting supply voltage and fault signal contact”, page 15).
• Make sure that the units are clean at all times.
Dirt results in malfunctions and in premature wear of the units.
• 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. Check for correct ground connection (see
chapter 5 "Maintenance”, page 17).
BA-en-2062-2106_ES24 9
• 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 "Maintenance”,
page 17).
• Wearers of cardiac pacemakers:
See separate operating instructions for the bar to be connected.
• 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
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).
2.4 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 chan-
ges or modifications in the operating instructions on request.
