2. Safety
The ES47 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 ES47 Power Supplies may be operated only in connection with the
Eltex R47 discharging bars, the R36 ion blower nozzles and the R55 ion
blower heads 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!
• Before starting the unit make sure that the appliance is permanently
grounded via the ground connection (5, Fig. 1). The ground cable
should have a minimum cross section of 1.5 mm2.
• 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 professionally or replaced
before continuing to operate the units.

BA-en-2075-1807_ES47 7
• 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.
• Any repair, maintenance or cleaning work must be carried out by quali-
fied personnel.
• If the housing cover is removed, contact protection is no longer effec-
tive. Always disconnect the power before opening the power supply
units.
• The protection class IP 54 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 and the elctrical supply is disconnected.
• Please note the maximum total lengths of the bars and the high voltage
cables in chapter 3.5.
• Make sure that the bars are clean at all times.
• 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 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).
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 Assembling 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.
3.2 Ground connection
A permanent ground connection must be made via the ground connection
(5, Fig. 1). The ground cable should have a minimum cross section of
1.5 mm2.
3.3 Selecting the discharging bars
Eltex R47 discharging bars, R36 ion blower nozzles and R55 ion blower
head for AC operation can be connected to the ES47 power supplies.

3.4 Connecting the high voltage cable
Warning!
Electric shock hazard!
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.
Method:
• Remove the cover of the power supply (see Fig. 1).
• Remove the nut from the connection at the high voltage cable.
• Insert the connection into the provided opening of the housing.
• Clamp the core of the high voltage cable to the high voltage socket X2.
• Fix the connection inside the unit with the locknut.
•Plug the flat connector of the cable shielding onto ground connection
X1.
Warning!
Terminals at the housing that are not used must be closed with blanking
plugs.

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 
limited. 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 bar length and the total length of all
high voltage cables. Fig. 4 demonstrates this principle for R47 bars.
Example: The maximum permissible total cable length with a 3 meter
active bar length is 7 meters.
3.6 Connecting the supply voltage
Connect the supply voltage via the power supply lead (4, Fig. 1) using an
earthing pin plug (depending on country).
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 EN 60947-2.

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 (1, Fig. 1) to switch on the power supply. In the ON
position the switch lights up green. High voltage is now supplied to the dis-
charging bars.
The output voltage is now a constant 5 kV AC.
If the fuse is defective, the switch will not light up.

5. Maintenance
Warning!
Electric shock hazard!
Switch the power supply off and disconnect the supply voltage before car-
rying out any maintenance or repair work. The machine in which the dis-
charging bars are installed must not be in operation. Maintenance work
must be carried out by trained or qualified personnel.
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!
Discharging bars
To ensure the proper function of the discharging bars, clean the bars at
least once a week using compressed air 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 (benzine). 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.
