This product is a corona discharge type electrostatic charge removal device.
The nozzle angle adjustable structure enables aligning the ionized air to desired area.
The check function which a considerable abrasion or dirt on the discharge needle
is notified via the output signal and the indicator is incorporated.
The air monitor function detects whether the air is supplied to this product or not.
When the air is not supplied, a corona discharge is stopped.

Never use this product with a device for personnel protection.
In case of using devices for personnel protection,use products which meet laws
or standards,such as OSHA ,ANSI or IEC etc.,for personnel protection applicable
in each region or country.
Do not use this product near or around surroundings containing any dangerous
materials, such as combustible material and flammable material.
Dust gathers on and around the discharge needle, and inside the nozzle depending on
the environment.
Be sure to clean up the discharge needle, periodically once a week or so, or this product
will be unable to exert the charge removal performance, which may also cause ignition or
product malfunction. However, when using this product in the environment exposed to
too much dust, be sure to clean up the discharge needle frequently.
Be sure to ground the main body of this product via ground terminal to ensure
electric shock prevention and reliable charge removal.
Since the discharge needle is live with high voltage, never touch the discharge
needle, or an electric shock may result.
If this product is used in an airtight room, ozone emitted from this product may be detrimental.
Therefore, in order for this product to be used in an airtight room, be sure to keep the room ventilated.
Since the ion air contains ozone, do not aim this product at anyone.
When loosening the nozzles for aligning the blowing air or maintenance, be sure to
stop applying air. Otherwise, the discharge needle may be flu out by air pressure.
Furthermore, after the work, screw up the nozzles by hand till they touch the main
body. Insufficient tightening may affect the charge removal capability or drop the
nozzles.
Since the tip of the discharge needle is pointed, take sufficient care in handling
the discharge needle, or injuries may result.

Make sure to use the DC power supply insulated by an isolation transformer etc.
for this product. If an auto-transformer etc. (single winding transformer) is used,
this product or the power supply may get damaged due to short-circuit.
When using as a CSA and UL compliant product, use a CLASS 2 CSA/UL certified
power supply, or a CSA/UL certified power supply that has been evaluated as a
Limited Power Source as specified in CAN/CSA-C22.2NO.60950-1/UL60950-1.

Since air pressure drops depending on the length of the air tube from the air supply
source or adding the pneumatic equipments (needle valve, speed-controler or
mini-filter etc.), take care that the air pressure of the supplied air to the product is
maintained. (The applied pressure should be checked around the air inlet of each
unit.) Furthermore, choose the appropriate pneumatic equipments in terms of air flow.

This product has been developed / produced for industrial use only.
Do not use this product beyond its rated specifications. Doing so can cause product breakdown
or damage. Furthermore, it may also cause a considerable reduction in product life.
Never disassemble, repair, modify, or misuse this product, as it can cause accident or
malfunction.
Do not throw this product in fire. There is a danger of it exploding, or generating poisonous gas.
Since this product emits ozone into the atmosphere, circulate the air if it is
foul-smelling. If ozone stays for long period, metals etc. may oxidize / decay.
Further, do not try to confirm the foul-smelling ozone by drawing your face near
the nozzle outlet. There is a danger of hurting your nose, throat, etc.
Do not use this product in steamy or dusty places and in places where water
splashes or spatter flies when welding.
Avoid use at an elevation higher than 2000m, and outdoor use.
Make sure that the power supply is off while wiring and inspection. Otherwise,
there is a danger of accident, electric shock or malfunction.
Do not use during the initial transient time (0.5 sec.) after the power supply is switched on.
Verify that the supply voltage variation is within the rating.
Do not turn the power back on immediately after it has been turned off,wait at
least 1 seconds before turning the power back on again.
If power is supplied from a commercial switching regulator, ensure that the frame
ground (F.G.) terminal of the power supply is connected to an actual ground.
In case a surge is generated in the used power supply, connect a surge absorber
to the supply and absorb the surge.
Do not run the wires together with high-voltage lines or power lines or put them in
the same raceway. This can cause malfunction due to induction.
After connecting the cables,check that the connections are correct before turning on the
power. If the cables are connected incorrectly,operating problems or accidents may occur.
Use air (dried clean air) for the fluid. Fluid other than air (dried clean air) or that
containing corrosive gas may cause accident or malfunction.
Do not use air containing foreign particles, such as, carbon dust or dust, water or
oil. Since those may cause electric shock or malfunction, take appropriate
measures, such as, installing an air-filter or an air-drier, etc.
Do not use this product for a purpose other than charge removal.
Do not block the air blowing outlet. Ozone is filled in the air, causing accident or
malfunction. (The air monitoring function detects by a falling of the applied air pressure.
Thus, if the air blowing outlet is blocked, the discharge is not halted by detection.)
Extension up to total 10m is possible with 0.15mm
2
, or more, cable. However, in
order to reduce noise, make the wiring as short as possible.
When this product is no longer usable or required, carry out the appropriate
disposal process meant for industrial waste.

MOUNTING
4
●
●
●
●
When this product is mounted on to a surface, use
M4 pan-head screw (please arrange separately).
The tightening torque should be 0.5N
･
m or less.
Be sure to ground the F.G. terminal. If the grounding is not
proper, the charge removal capability deteriorates
considerably. (Direct earth or power supply common earth)
The power supply common earth can also be connected with the accessory lead wire for F.G.connection.
0V earth: Connect No. 2 and No. 3 of the end connector (9-way) with the lead wire for F.G.connection.
+V earth: Connect No. 1 and No. 3 of the end connector (9-way) with the lead wire for F.G.connection.
Wrong wiring of the grounding causes accident or malfunction. Check the grounding condition
to be used beforehand and take care not to short-circuit the power supply when wiring.
If AC adapter is used, be sure to connect the F.G. terminal to the power supply common earth. For details of
wiring, refer to the instruction manual enclosed with the AC adapter for
ER-VW
series (
ER-VAPS1-W
).

●
Screwing the nozzle down.
Aim the nozzle to the object being charged.
After aligning, tighten the nozzle by hand till it touches the
main body and confirm that the nozzle doesn't move.
If the nozzle is not tightened enough, the charge removal
capability may deteriorate or the nozzle may drop.
The adjustable range of the nozzle is shown in the right figure.
