Safety Precautions

■ General Precautions

• At startup and during operation, be sure to monitor the functions and

performance of the SJ-M 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-M 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-M Series is used in combination with other instruments,

functions and performance may be degraded, depending on operating

conditions and the surrounding environment. Use the SJ-M after fully

studying the effect of combined use with other instruments.

• Do not use the SJ-M Series for the purpose of protecting the human body.

■ SJ-M Series Handling Precautions

The SJ-M Series isa high-voltage product that is not designed in an explosion-proof structure. Pay

attention to the following when using the SJ-M Series.

•

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

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

•

The power cable supplied with the exclusive power supply (SJ-U2) is a 125 V

rated power cable. When connecting a power supply that exceeds this power

rating to the SJ-M Series, the user must prepare a power cable having

adequate voltage rating. If a power cable that does not meet the voltage

rating is used, this may cause electric shock, fire or malfunction.

•

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, tools, wire or other metallic objects near this

product. Doing so may cause electric shock or malfunction.

•

If the SJ-M Series is used in an airtight location, the generated ozone may be

harmful. Be sure to ventilate the area when using the SJ-M Series.

•

Do not use this product in locations where sudden changes in temperature

or condensation are likely to occur.

•

Do not operate this product with wet hands. Doing so may cause electric

shock.

•

Before starting inspection or maintenance, be sure to turn the power OFF.

Failure to do so might result in electric shock or malfunction.

•

During maintenance, do not directly touch the electrode probe. 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.

•

Take soundproofing measuressuch as wearing earplugs when using the

SJ-M Series.

CAUTION

WARNING

• Do not touch the electrode probe with a tool or other hard object. Damage to

the electrode probe 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 probe

become dirty due to the adhesion of dust and dirt. If the ion level alarm

indicator or condition alarm indicator lights, clean the electrode probe. If the

product is used with the electrode probe 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 probe (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 might result in

accident or malfunction.

• Use this product for static elimination only. Do not use it for other purposes.

• When installing the SJ-M Series, observe the minimum bending radius of all

provided cables. Also,

do not install

the SJ-M with the cab

les deformed by

staples or other objects. Doing so might cause the SJ-M to malfunction.

■ 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 en sure safety and appropriate static elimination, be sure to ground this

product.

• Be sure to connect a Class D ground (maximum resistance of 100 Ohms).

■ Air Purge Function Precautions

• Be sure to use an air pressure of 0.7 MPa or less.

• Be sure to supply clean or dry air of temperature –20°C or more through a

filter of mesh size about 0.01μm. Moisture or oil contained in the air or

nitrogen may cause discharge inside the Static Elimination Head, which

may result in accidents or malfunction.
