Safety Precautions
■ General Precautions
• At startup and during operation, be sure to monitor the functions and
performance of the SJ-F300 Series.
• We recommend that you take substantial safety measures to avoid any
damage in the event that a problem occurs.
• Do not modify the SJ-F300 Series or use it in any way other than described
in the specifications. The functions and performance of products used or
modified in this way cannot be assured.
• When the SJ-F300 Series is used in combination with other instruments,
functions and performance may be degraded, depending on operating
conditions and the surrounding environment.
• Do not use the SJ-F300 Series for the purpose of protecting the human
body.
■ SJ-F300 Series Handling Precautions
The SJ-F300 Series is a high-voltage product that is not designed in an explosion-proof structure. Pay
attention to the following when using the SJ-F300 Series.
• To prevent electric shock and to ensure accurate static elimination, be sure
to connect a Class D earth (maximum resistance of 100 Ohms).
• Do not use this product in locations where there is the risk of ignition or
explosion from flammable solvents or dirt and dust.
• High voltage is applied to this product. Prevent it from being splashed with
water, oil, or flammable solvents. Failure to do so may cause insulation
breakdown, which will result in electric shock or malfunction.
• Do not bring your fingers or tools, wire or other metallic objects near this
product. Doing so may cause electric shock or malfunction.
• Do not use this product in a non-ventilated location. The ozone generated
from this product may become toxic. Be sure to ventilate the installation site
when this product is used in a non-ventilated location.
• Do not use this product in locations where sudden changes in temperature
or condensation are likely to occur. Doing so may cause accidents or
malfunction.
• Do not operate this product with wet hands. Doing so may cause electric
shock.
• Before starting maintenance, be sure to turn the power OFF. Failure to do so
may result in electric shock or accidents.
• During maintenance, do not directly touch the electrode needles. Doing so
may cause personal injury.
• If any malfunction is observed in this product, immediately turn it OFF, and
contact your nearest agent. You should never repair this product yourself.
Doing so may cause electric shock or malfunction.
Do not touch the electrode needles with a tool or other hard object. Damage to
the electrode needles will prevent static elimination performance from being
fully demonstrated, and cause accidents or malfunction.
CAUTION
WARNING
CAUTION
• When this product is used for a long period of time, the electrode needles
become dirty due to the adhesion of dust and dirt. If the ion level alarm
indicator or condition alarm indicator lights, clean the electrode needles. If
the electrode needles are used in a dirty or dusty state, the static elimination
performance can no longer be fully demonstrated, resulting in accidents or
malfunction. We recommend periodically cleaning the electrode needles (as
a guideline, once every two weeks in a regular operating environment
though this depends on the installation conditions).
• Do not drop or subject this product to shock. Doing so may result in
accidents or malfunction.
• Use this product for static elimination only. Do not use it for other purposes.
■ Power Supply Precautions
• Use a DC power supply with rated 24 V output.
• Noise applied to the power supply may cause this product to malfunction. If
this happens, install an insulated transformer.
• When using a switching regulator, be sure to connect a Class D earth to the
Frame Ground terminal.
■ Grounding Precautions
• To ensure safety and appropriate static elimination, be sure to ground this
product.
• Be sure to connect a Class D earth (maximum resistance of 100 Ohms).
■ SJ-F300 Series Warning Label
A WARNING label is affixed on the SJ-F300 Series to ensure safety.
Read the description on this WARNING label to ensure correct use of the SJ-F300 Series.
CAUTION
CAUTION
CAUTION
Be sure to turn the power off when replacing
the electrode probes. Otherwise, electric shock may occur.
Do not touch electrode probes with your hands
or fingers, as this may cause injury.

■ Installation Precautions
Avoid installing the SJ-F300 Series in the following locations as this may
cause accidents.
• Locations directly subject to vibration and shock
• Locations subject to ambient temperature out of the 0°C to +50°C range
• Locations subject to ambient humidity out of the 35 to 65%RH range
(condensation not allowed)
• Locations subject to sudden changes in temperature
• Locations subject directly from blasts from air conditioners
• Locations subject to volatile or flammable substance, solvents or corrosive
gases
• Locations subject to large amounts of dirt, and dust, salt, iron and oil smoke
• Locations that may be splashed with water, oil or chemical mist
• Locations where strong magnetic and electrical fields are generated
■ About Warming Up the SJ-F300 Series
Leave the SJ-F300 Series for about 20 minutes after turning the power ON to allow
the ion balance to stabilize.
The ion balance may be unstable during this warming up period.
■ Other Precautions
• Be sure to read the WARNINGS and CAUTIONS described in each of the
items in this Instruction Manual.
• The Static Elimination Blower Unit has a built-in EEPROM. Do not turn the
Static Elimination Blower Unit OFF during the setup.
Refer to the following diagram when installing the SJ-F300 Series.
• Install the Static Elimination Blower Unit away from the wall or surrounding
objects.
• Install the Static Elimination Blower Unit so that the Electrode Unit can be
removed for replacement.
