Dear Customer,
The ES53 high voltage power supplies and the EX discharging bars are
designed for the active discharging of disruptive static charges which
develop in production processes in explosion hazard area.
The discharging bars and the power supply are used mainly in cases
where disruptive static charges on fast-moving material webs impair pro-
duction processes and need to be eliminated. The power supply delivers
an alternating voltage of 5 kV at 50...60 Hz.
The ES53 power supply complies with the requirements of the EX dis-
charging bar approval (details in Operating Instructions of discharging bar)
and features the following characteristics:
• 5 plug-type high voltage outputs
• stable 5 kV AC output voltage
• small dimensions
• easy installation
• protection class IP54 design
• function and pollution monitoring of the bars with floating signal
contacts (optional)
• complies with the approval specifications for Eltex EX bars.
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 feedback from the users of our
appliances.

2. Safety
The ES53 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 in explosion
hazard area.
The manufacturers will not assume any liability and warranty if the units
are used improperly or outside the intended purpose.
For warranty conditions, please refer to the General Terms and Conditions
(GTC), see www.eltex.de.
2.1 Proper use
The ES53 Power Supplies may be operated only in connection with the
appropriate Eltex discharging bars for AC operation (see Technical Speci-
fications).
Modifications or changes made to the power supplies or discharging bars
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 injury.
Caution!
This symbol appearing in the operating instructions refers to operations
which, if carried out improperly, may result in damage to property.
Ex Warning!
This symbol denotes the special conditions which must be observed when
operating the system in explosion hazard areas as specified in the EX
approvals.

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 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).
• Any work involving the units must be carried out by qualified electrici-
ans (see chapter 5 "Maintenance”, page 16, chapter 6 "Trouble-shoot-
ing”, page 17).
• The unit may only be used by qualified personnel trained for explosion
hazard areas.
• The power supply must be installed outside the explosion hazard area
(see chapter 3.1 "Assembly the power supply”, page 11).
• 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).
BA-en-2018-2307_ES53 9
• 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 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.
• 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 16, chapter 6 "Trouble-shooting”, page 17).
•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 17).
• 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
Ex!
10 BA-en-2018-2307_ES53
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.
