Safety Precautions
„ General precautions
• You must verify that the SJ-H* Series are operating correctly in terms of functionality and
performance before the start and the operation of the SJ-H* series.
• We recommend that you take substantial safety measures to avoid any damage in the
event of a problem occurring.
• KEYENCE never warrant the function or performance of the SJ-H* Series if it is used in a
manner that differs from the SJ-H* Series specifications contained in this instruction man-
ual or if the SJ-H* Series are modified by yourself.
• Do not use the SJ-H* Series for the purpose of protecting the human body.
„ Warnings and cautions specific to the SJ-H* Series
The SJ-H* Series is a high-voltage device that is not designed to be explosion proof. Before using the
SJ-H* Series, be sure to read the following warnings and precautions carefully.
• Filling a closed space with nitrogen will reduce the oxygen levels in the air to dangerous
levels.
Make sure that there is adequate ventilation when using the SJ-H* Series in an enclosed
space.
• Do not use the SJ-H* Series in the presence of flammable or explosive gases or elements.
• To avoid the risk of electric shock and ensure proper static elimination, be sure to com-
pletely ground the SJ-H* Series' 10-pin I/O cable.
• To avoid the risk of electric shock or product malfunctions, prevent water, oil, or flammable
solvent from splashing onto the SJ-H* Series.
• To avoid the risk of electric shock or product malfunctions, keep fingers and metallic
objects such as tools or wires away from the SJ-H* Series during operation.
• When the SJ-H* Series is used in an enclosed space, the generated ozone may become
harmful.
Make sure that there is adequate ventilation when using the SJ-H* Series in an enclosed
space.
• Do not use the SJ-H* Series in a location in which the temperature changes suddenly, or
where condensation occurs. This may lead to an accident or product breakdown.
• To avoid the risk of electric shock, do not operate the SJ-H* Series with wet hands.
• To avoid the risk of electric shock or product malfunctions, be sure to turn the power off
during maintenance of the SJ-H* Series.
• To avoid the risk of injury, do not touch the electrode probes directly with your hands or fin-
gers during maintenance.
• If any abnormality is observed in the SJ-H* Series, immediately turn off the power and
contact the nearest KEYENCE office. Do not try to repair the SJ-H* Series by yourself.
This may cause electric shock or product malfunctions.
• Do not touch the SJ-H* Series' electrode probes with hard objects such as tools. If the
electrode probes are damaged, the SJ-H* Series does not operate properly, resulting in
product malfunctions.
• Operate the control panel of the SJ-H* Series with the flat-blade screwdriver provided with
the product.
• When mounting the SJ-H* Series, use the provided End units (L/R) and Auxiliary Support
Part, otherwise product malfunctions may result.
• When the SJ-H* Series is used over a long time, dust accumulates on the electrode
probes. Clean the electrode probes when the alarm indicator flashes. If you continue to
use the SJ-H* Series with dust accumulating on the electrode probes, the SJ-H* Series
will not operate properly, resulting in product malfunctions. Regular cleaning (about every
2 weeks) is recommended.
• Do not drop the SJ-H* Series or subject it to a strong impact. This may cause product mal-
functions.
• Do not use the SJ-H* Series for any purpose other than eliminating static electricity.
• When the SJ-H* Series is used in combination with other instruments, functions and
performance maybe degraded, depending on operating conditions and the surrounding
environment.
„ Precautions for power supply
• Use a DC power supply at a rated supply voltage of 24 to 36 V.
• Noise conveyed through the power supply line may cause the SJ-H* Series to malfunction.
Be sure to use a stabilized DC power supply with an insulated transformer.
• When using a commercially available switching regulator, be sure to completely ground
switching regulator's frame ground terminal.
• Do not connect a number of power supplies to a single SJ-H* unit or more than one SJ-H*
unit connected together, otherwise the power supplies will be short-circuited and product
malfunctions may result.
„ Precautions for grounding
The 10-pin I/O cable for the SJ-H* Series is provided with a ground wire.
• For proper static elimination, be sure to completely ground the SJ-H* Series' grounding
cable.
• The grounding cable must be grounded at a resistance not exceeding 100 Ω.
„ Warning labels on SJ-H* Series
For safety reasons, the warning labels are attached to the SJ-H* Series. Read each label carefully
and follow the instructions on the labels.
„ Locations
To prevent product malfunctions, avoid installing the SJ-H* Series in the following locations.
• Locations in which the SJ-H* Series may be directly subjected to vibration or impact.
• Locations in which the ambient temperature drops below 0 °C or exceeds + 40°C.
• Locations in which the relative humidity drops below 35% or exceeds 85%, or where
condensation occurs.
• Locations in which the temperature changes suddenly.
• Locations in which the SJ-H* Series is exposed to a direct breeze from an air conditioner.
• Locations in which there are volatile, flammable substances or corrosive gas.
• Locations exposed to dust, salt, metal particles, or greasy fumes.
• Locations in which water, oil or chemicals may splash onto the SJ-H* Series.
• Locations in which a strong magnetic or electric field is generated.
• Locations where the altitude exceeds 2000 m.
• Outdoors
„ Other precautions
• Follow the warning instructions and cautions specified in this instruction manual.
• The SJ-H* Series uses an EEPROM. Do not turn off the unit while settings are made in
the SJ-H* Series.
