2. Safety
The ES51 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 ES51 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 8!
• Before carrying out repairs, cleaning or maintenance work involving the
power supplies and the discharging bars, switch off the power supply
and disconnect the mains power supply (see chapter 5 "Maintenance”,
page 16, chapter 6 "Trouble-shooting”, page 17).
• 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 16, chapter 6 "Trouble-shooting”, page 17).

BA-en-2014-2006_ES51 9
• Any work involving the units must be carried out by qualified electri-
cians (see chapter 5 "Maintenance”, page 16, chapter 6 "Trouble-
shooting”, page 17).
• Before starting the unit make sure that the appliance is permanently
grounded via the grounding terminal (6, Fig. 1). The ground cable
should have a minimum cross section of 1.5 mm2(see chapter 3.2
"Ground connection”, page 11).
• Check the power supplies and the discharging bars at regular intervals
for any damage to the electrical wiring and the high voltage cables. Any
damaged components must be repaired or replaced before continuing
to operate the units.
• If the housing cover is removed and the supply voltage is switched on
at the same time, contact protection is no longer effective. Always dis-
connect the power before opening the power supply units.
• The protection class IP54 only applies if the housing cover is closed
and the cable connections are shrouded.
• Connect/disconnect the discharging bars only if the power supply unit is
switched off (see chapter 3.4 "Connecting the high voltage cable”,
page 12).
• In applications involving moving bars (e.g. film draw strips), the high
voltage cable must be attached such that there is no cable movement
near the connection zone of the power supply unit (see chapter 3.4
"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 13).
• 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 13).
• 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 15).
• 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 16).
• Make sure that the bars are clean at all times. Dirt results in malfunc-
tions and in premature wear of the units.

10 BA-en-2014-2006_ES51
• 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 16, chapter 6 "Trouble-shooting”, page 17).
• Potential risk for wearers of cardiac pacemakers:
Moving the chest closer than 3.5 cm to the emission tips of the dis-
charging 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 dis-
played.
• 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
changes or modifications in the operating instructions on request.

3. Installation and assembly
3.1 Assembly the power supply
The power supply is designed for wall mounting. Attach using the brackets
provided (installation dimensions, see Fig. 2). The operating elements of
the power supply and the terminals must be freely accessible at all times
and the display LEDs must be visible.
3.2 Ground connection
A permanent ground connection must be made via the grounding terminal
(6, Fig. 1). The ground cable should have a minimum cross section of
1.5 mm2.

3.3 Selecting the discharging bar
Eltex discharging bars and ion blowers for AC operation can be connected
to the ES51 power supplies.
3.4 Connecting the high voltage cable
Warning!
Connect or disconnect the high voltage cables only with the power supply
switched off!
Connect the discharging bars to the power supply using the prefabricated
high voltage cable. Push the high voltage cables into the sockets up to the
stop. Then secure the adapter in the socket with the clip provided (see
Fig. 3).
Cables without adapter carry a coloured marking on the flexible tubing.
This marking must lie flush with the outside edge of the coupling. Cables
without flexible tube and cables with plug-type adapters are plugged in
flush and secured with the clip.
Warning!
In applications involving moving bars (e.g. film draw strips), the high volt-
age cable must be attached such that there is no cable movement near
the connection zone of the power supply unit.

BA-en-2014-2006_ES51 13
3.5 Maximum active bar length and length of the high
voltage cable
Both the lengths of the high voltage cable and of the active bars are lim-
ited. The shielded high voltage cables cause a capacitive load on the
transformer inside the power supply. The maximum loading capacity is a
result of the function of the total active bars length and the total length of
all high voltage cables. Fig. 4 demonstrates this principle for R5x bars.
Example: The maximum permissible total cable length with a 3 meter
active bar length is 32 meters.
3.6 Connecting supply voltage
Depending on the design of the power supply, connect the supply voltage
via the power supply lead (1, Fig. 1) using an earthing pin plug (depending
on country); Overvoltage category II (exception: overvoltage category III
for version ES51/S).
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 con-
tact 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.
For external security of the power supply the following circuit breaker is
recommended: Tripping Characteristic 2A / K according to DIN VDE 0660
Part 101, DIN EN 60947-2 and IEC 947-2.

4. Operation
4.1 Startup
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.
Use the toggle switch (4, Fig. 1) to switch on the power supply. In the ON
position the switch lights up green. High voltage is now supplied to the
discharging bars.
The output voltage is now a constant 5 kV AC.
If the fuse is defective, the switch will not light up.
4.2 Function and pollution monitoring (optional)
In general, proper operation is indicated by the illuminated switch in all
units.
The optional function and pollution monitoring analyses the high voltage
signal at the output.
• High voltage is indicated by a green LED in the front panel (active). A
floating change over contact is available for transmitting this signal.
• If a defect or fault is detected (e.g. sparking, dirt or arcing at defective
cable), the fault signal will be activated and displayed via a red LED in
the front panel (fault). The signal is available at a
second floating change over contact.
Note!
The fault will not be stored. Once the cause of the fault has been reme-
died, the fault signal goes off.
Dirt beginning to settle on a discharging bar is initially indicated by an
irregular response of the fault signal. This must be kept in mind when
processing the fault signal further.

5. Maintenance
Warning!
Electric shock hazard!
• Switch the power supply off and disconnect the supply voltage before
carrying out any maintenance or repair work.
• The machine in which the discharging bars are installed must not be in
operation.
• Any work involving the units must be carried out by qualified electri-
cians.
5.1 Power supply
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. The intervals for the check depend on the appli-
cation and must hence be defined by the user according to the operating
conditions. The power supply itself does not require any maintenance.
Check for correct ground connection!
5.2 Discharging bars
To ensure the trouble-free function of the discharging bars, clean the bars
at least once a week with compressed air free of oil and water (max. 6 bar
and standard compressed air pistol) and a brush with soft plastic bristles.
Refer to the operating instructions for the bar used.
Dirt deposits settling on the bars (e.g. grease) must be cleaned off using a
suitable solvent (cleaning gasoline). Do not soak the bars and the high
voltage cable in solvent!
Caution!
Risk of deflagration!
Allow the solvent to evaporate completely before restarting the unit.
Do not damage the emission tips of the bars.
