Safety Precautions
■ General Precautions
CAUTION
• 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.
WARNING
• 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.
CAUTION 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
• 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
CAUTION
• 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
CAUTION
• 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.
Be sure to turn the power off when replacing
WARNING
the electrode probes. Otherwise, electric shock may occur.
Do not touch electrode probes with your hands or fingers, as this may cause injury.
* WARNING labels in Japanese, German, French, Italian and Chinese:SC are provided.
Use them as necessary.
■ Installation Precautions
CAUTION
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
Note:
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
CAUTION • 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.
CAUTION Refer to the following diagram when installing the SJ-F300 Series.
• Install the Static Elimination Blower Unit away from the wall or surrounding objects.
50 mm or more
50 mm or more
•Install the Static Elimination Blower Unit so that the Electrode Unit can be removed for replacement.

2-1 Before Installation
Before you install this product, examine carefully the distance between the Static Elimination Blower Unit and the target object and the time required for static elimination.
About Static Elimination Performance
The following shows a typical example where static is eliminated from an aluminum plate (20 pF) 150 mm x 150 mm square charged to +1000 V by this product.
The blow rate of the blower is set at maximum (FAST).
■ Static elimination area
The following graphs show the relationship between the time required for eliminating static from a target object charged from +1000 V to +100 V and the distance from the charged object up to the Static Elimination Blower Unit.

2-1 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.
