Safety Precautions

■ General Precautions

• At startup and during operation, be sure to monitor the functions and performance of the SJ-F031/036.

• We recommend that you take substantial safety measures to avoid any damage in the event that a problem occurs.

• Do not modify the SJ-F031/036 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-F031/036 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-F031/036 for the purpose of protecting the human body.

■ SJ-F031/036 Handling Precautions

The SJ-F031/036 is a high-voltage product that is not designed in an explosion-proof structure. Pay attention to the following when using the SJ-F031/036.

• To prevent electric shock and to ensure accurate static elimination, be sure

to connect a Class D ground (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 blinks in red 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 ground 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 ground (maximum resistance of 100 Ohms).

■ SJ-F031/036 Warning Label

A WARNING label is affixed on the SJ-F031/036 to ensure safety. Read the description on this WARNING label to ensure correct use of the SJ-F031/036.

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.

2-1 Before Installation

Before you install this product, examine carefully the distance between the Static Elimination Blower 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.

■ Static elimination time

The following graphs show the relationship between the time required for eliminating static at the maximum blow rate from a target object charged at +1000 V positioned 300 mm apart from the Static Elimination Blower and the charged level.

■ 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 (grounded body). Eliminate static from the target body at locations where it is not directly touching metallic bodies (grounded body).

Static will be eliminated from only the surface of the insulated body (film, sheet, etc.) that is facing the Static Elimination Blower. When eliminating static from both sides of a target body, install two Static Elimination Blowers as one unit must be installed on either side of the target body.

Install the Static Elimination Blower so that it can be easily accessed, for example, for replacement of parts and cleaning.
