(1) Power switch
Turns the power supply ON/OFF.
(2) Error output indicator
This indicator lights red during an error output.
(3) Cleaning notice/warning indicator
This indicator flashes orange to notify you that the discharge needles are dirty and
the product's neutralizing capabilities are about to drop. This indicator will stop
flashing and stay lit when the discharge needles become even dirtier and the
product's neutralizing capabilities can no longer be sustained.
(4) Power indicator
This indicator lights green when the power is ON.
(5) Ion balance adjustment button
Pressing this button adjusts the ion balance.
(6) Power input/signal output connector
Power can be supplied and output managed via this connector when the Air Clean
Unit is connected.
When the Air Clean Unit is not connected, 24 VDC power can be input. The
cleaning notice, cleaning warning operation (Unit turned OFF when a warning is
output) and error output (Unit turned OFF when an error is output) can be output.
(7) GND terminal
Terminal for connecting the ground
(8) AC adapter terminal

The following summarizes the colors and wiring of the I/O cable provided with the
ZN-J25, and output specifications.

Distance: 300 mm, Air Clean Unit: ZN-A2502 with air level 5, At center of air
outlet, Neutralization: From
±
1000 V down to
±
100 V with Charge Plate
monitor (150 x 150 mm, 20 pF)
Temperature: 18

to 28
℃
Humidity: 35% to 55%
The performance might not be able to be satisfied when there is gas such as
solvent gas in the measurement area.

The performance might not be able to be satisfied when there is gas such as
solvent gas in the measurement area.
(9) Discharge needles
Ions are generated by applying a high voltage to these discharge needles and
discharging corona.
(10) Ion balance sensor
This sensor detects the balance of the ions emitted from the discharge needles, and
this information is used as feedback to automatically control the ion balance.
(11) Mount holes
Holes for mounting this product on an Air Clean Unit, clean booth panel or other
equipment

PRECAUTIONS FOR SAFE USE
INSTRUCTION SHEET
Thank you for selecting OMRON product. This sheet primarily
describes precautions required in installing and operating the
product.
Before operating the product, read the sheet thoroughly to acquire
sufficient knowledge of the product. For your convenience, keep
the sheet at your disposal.

ZN-J25A
Air Clean Ionizer
Please observe the following precautions to prevent failure to operate, malfunctions,
or undesirable effects on product performance.
1. Installation Site
Do not install this product in locations subjected to the following conditions:
• Ambient temperature outside the rating
• Ambient humidity outside the rating
• Presence of corrosive or flammable gases
• Presence of dust, salt, or iron particles
• Presence of particles and dust
• Direct vibration or shock
• Direct sunlight
• Water, oil, or chemical fumes or spray
• Devices (e.g. precision equipment) susceptible to the influence of peripheral
noise
• Strong magnetic or electric field, and charged objects
* Precautions for Installation and Use
The two metal bars on the enclosure opening are sensor electrodes. The ion
balance can no longer be controlled if charged objects are located around this
product. Do not bring charged objected within about 150 mm of this product.
2. Power Supply and Wiring
• When using a 24 VDC power supply:
Connect the 24 VDC power supply to the rear connector using the I/O cable.
When supplying power by the I/O cable, do not connect the AC adapter at the
same time.
Do not ground the 24 VDC terminal.
• When supplying power from the Air Clean Unit:
Connect the power supply to the ZN-J25A using the exclusive cable (provided).
Do not connect the AC adapter at the same time.
• If surge current is present in the power lines, connect surge absorbers that suit
the operating environment.
• When connecting the power and output lines, pay attention to the polarity of the
lines.
The supply voltage must be within the rated range.
• When connecting the power line, do not short-circuit the power supply.
• When connecting the output line, the supply current must be within the rated
range.
• Always ground the GND terminal. Using the product without the GND
terminal grounded may cause the ion balance to deviate.
• High-voltage lines and power lines must be wired separately from this product.
Wiring them together or placing them in the same duct may cause induction,
resulting in malfunction or damage.
3. Maintenance and Inspection
• Periodically clean the discharge needles as dirt on these needles causes the
amount of generated ions to fall or the ion balance to deviate.
• Always wait at least one minute after turning the power supply OFF before
cleaning or connecting/disconnecting the discharge needles.
• Do not touch the discharge needles directly with your hands.
• Use ethanol or isopropyl alcohol to clean the discharge needles. Do not use
paint thinner, benzene, acetone or kerosene.
• This product neutralizes static electricity on charged objects by ionizing air by
corona discharge and spraying ions at charged objects from an Air Clean Unit.
• An Air Clean Unit (ZN-A2502, sold separately) can also be installed and connected
to this product at the same time. This eliminates the need for individual installation
and wiring of the Ionizer.
• Compared with bar-type ionizers, this product can be installed with minimal
blocking of laminar airflow from an Air Clean Unit.
• The Auto Ion Control function keeps the ion balance in an optimum state.
The warning labels written in Japanese are affixed to the body. For countries
other than Japan, warning labels must be replaced by English ones (supplied with
the product).

Alert Statements in This Instruction Sheet
Indicates a potentially hazardous situation which, if not
avoided, will result in minor or moderate injury, or may
result in serious injury or death. Additionally, there may be
significant property damage.
WARNING
When screw-fastening the body for use, vibration or the
body’s own weight may cause it to fall, and cause an injury
if the screws are not sufficiently tightened.
Mount the body using M4 screws tightened to a tightening
torque of 1.2 to 1.6 N.m.
Water droplets entering the body and coming into contact
with the electrical circuit may cause the circuit to ignite.
Do not use the product in locations subjected to
condensation or in highly humid atmospheres.
