• 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 be
damaged due to short-circuit.
• 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.
• If the power supply is switched on immediately after
being switched off, fault output may be generated. After
the power supply is switched off, wait at least 1 sec.
before switching it 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.
•
Confirm the wiring and piping state before supplying
power or air. Wrong wiring and piping may cause
malfunction.
•
Use air (dry, clean air) for the fluid. Any fluid other than
air (dry, clean air) or even air containing corrosive gas
may cause an accident or malfunction.
• Do not use air that contains foreign particles, e.g. carbon
dust, dust, water or oil.
Since these substances may cause electric shock or
malfunction, take appropriate countermeasures, e.g.
install an airfilter, air-drier, etc.
• Do not use this product for any purpose other than
charge removal.
• Do not cover the ionized air outlets of the nozzles. Ozone
may build up and operating problems or failure may
occur. (The air monitoring function checks if the pressure
of air supplied to the unit drops, so if the ionized air
outlets of the nozzles are covered, it will not detect this
and will not cause charge removal operation to stop.)
• This product is CE-conformed under the EMC Directive.
The immunity adopted by this product should be
conformable to EN 61000-6-2. In order for such immunity
to be conformable to this standard, all wires connected to
this product should be limited in length to less than 10 m
32.808 ft
.
• When this product is no longer usable or required,
dispose of properly as industrial waste.
• Always be sure that the power supply and the
air supply are both turned off before inspection
and cleaning.
•
Be sure to turn off the air before removing the
nozzles for purposes such as maintenance.
Air pressure may cause the discharge needles
to fly out.
PRECAUTIONS FOR PROPER USE
• Since the removal discharge effect will deteriorate if
dirt is stuck to the tip of the discharge needle, clean the
discharge needle periodically.
• The maintenance required depends on the environment
of use. As a reference, the maintenance should be done
once in two weeks.
• The discharge needle is a part having a product life time.
It is recommended that the needle should be replaced, as
a reference, after 10,000 hours in use. When replacing it,
replace the whole unit (
ER-VWANT
).
Cleaning procedure and discharge needle replacement procedure
1
Check that the power is turned off.
2
Check that no air is being supplied.
3
Turn the nozzle
counterclockwise to remove it.
4
Replace the discharge needle
unit, or use a cotton swab
moistened in alcohol to clean the
discharge needle and the area
around it.
For the needle discharge unit while running it along the
guide at the side of the opening.
5
After cleaning, turn the nozzle clockwise to install it.
Securely tighten the nozzle by hand until it is touching
the enclosure, and check that the nozzle does not move.
If the nozzle is not installed correctly, it will adversely
affect charge removal performance and the nozzle may
also fall out.

•
Do not use this product beyond its rated specifications.
Doing so can cause product breakdown, non-function,
or damage. Furthermore, it will also cause a marked
reduction in product life.
• Never disassemble, repair, modify, or misuse this
product, as this can cause an accident or malfunction.
•
Do not throw this product into fire: it may explode or
generate poisonous gas.
• Since this product emits ozone into the atmosphere,
circulate air to prevent foul smells.
If ozone lingers for long periods, metals, etc. may oxidize /
decay. Furthermore, do not try to confirm that foul smells
are caused by the ozone by drawing your face near the
nozzle outlet and air outlet: you may hurt your nose,
throat, etc.
• Do not use this product in steamy or dusty places, in
places where water and oil splash, or where spatter flies
when welding.
