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.
• 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

Before Installation
■ Appropriate static elimination method
Pay attention to the following points to ensure that static
elimination is performed appropriately.
Static elimination cannot be performed accurately at
locations where the target object is touching a metallic
body (earthed body).
Eliminate static from the target body at locations where it is
not directly touching metallic bodies (earthed body).
Static will be eliminated from only the surface of the
insulated body (film, sheet, etc.) that is facing the Static
Elimination Blower Unit.
When eliminating static from both sides of a target body,
install two Static Elimination Blower Units as one unit must
be installed on either side of the target body.
Install the Static Elimination Blower Unit so that it can be easily accessed, for
example, for replacement of parts and cleaning.
Installation Precautions
■ Installation site
