Safety Information for SJ-M Series
n General Precautions
n SJ-M Series Handling Precautions
• Do not use this product for the purpose to protect a human body or a part
of human body.
• This product is not intended for use as explosion-proof product. Do not
use this product in hazardous location and / or potentially explosive
atmosphere.
• You must verify that the SJ-M Series is operating correctly in terms of
functionality and performance before the start and during the operation of
the SJ-M Series.
• We recommend that you take substantial safety measures to avoid any
damage in the event of a problem occurring.
• KEYENCE never warrants the function or performance of the SJ-M201
Series if it is used in a manner that differs from the SJ-M201 Series
specifications contained in this instruction manual or if the SJ-M201 Series
is modified by yourself.
• When the SJ-M201 Series is used in combination with other instruments,
functions and performance maybe degraded, depending on operating
conditions and the surrounding environment.
WARNING
CAUTION
NOTICE
• Ensure you use only in well-ventilated areas as the ozone released from
the device can become harmful if used in an enclosed space. Do not place
your face close to the end of the Static Elimination Head. The ozone
released from the head can cause damage to the nose and/or throat.
• Do not touch static elimination head after turning the power on.
High voltage may occur on the surface of this product when neutralizing
highly-charged objects.
• To prevent electric shock and to ensure accurate static elimination, be sure
to connect a Class D earth (maximum resistance of 100 Ohms).
• The accessory AC power cable to Power SJ-UI/SJ-U2 (sold separately), is
rated for AC 100 to 125 V and is specifically for use in Japan.
When using the SJ-M Series outside of Japan, you cannot use the AC
Power Cable described above. Use an AC Power cable best suited to the
regulations and standards of the country or region the SJ-M Series is
going to be used.
• 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 injury, electric shock, or malfunction.
• 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.
• Supply air according to the deratings indicated in the specifications. Use
without performing derating might result in electric shock or malfunction
• 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.
• Use this product for static elimination only. Do not use it for other purposes.
WARNING
CAUTION
■ Air For Supply
■ Power Supply Precautions
■ Air Purge Function Precautions
• Protect the area around the tip of the Static Elimination Head with silicon,
fluoro-resin or other highly ozone-resistant resin.
• Do not use this product in locations where sudden changes in temperature
or condensation are likely to occur.
• 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
may 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.
• When installing the SJ-M Series, observe the minimum bending radius of
all provided cables. Also, do not install the SJ-M with the cables deformed
by staples or other objects. Doing so might cause the SJ-M to malfunction.
CAUTION
• The only gas that can be supplied to the SJ-M201 is air.
• The compressed air flowing from the compressor contains drain such as
water and oil. Please remove drains from air by using filters or air dryers
before use.
• When the gas contains foreign materials, remove them by use of filters or
the likes.
CAUTION
Use a rated power supply.
• 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.
CAUTION
NOTICE
• Be sure to use air of pressure 0.001 MPa to 0.5 MPa. Use outside of the
rated air pressure range might result in accidents or malfunction.
• Be sure to supply clean, 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. CAUTION
