Safety Precautions
■
General precautions
• You must verify that the SJ-HA Series are operating correctly in terms of functionality and
performance before the start and the operation of the SJ-HA 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-HA Series if it is used in a
manner that differs from the SJ-HA Series specifications contained in this instruction man-
ual or if the SJ-HA Series are modified by yourself.
• Do not use the SJ-HA Series for the purpose of protecting the human body.

Warnings and cautions specific to the SJ-HA Series
The SJ-HA Series is a high-voltage device that is not designed to be explosion proof. Before using
the SJ-HA 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-HA Series in an enclosed
space.
• Do not use the SJ-HA Series in the presence of flammable or explosive gases or ele-
ments.
• To avoid the risk of electric shock and ensure proper static elimination, be sure to com-
pletely ground the SJ-HA 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-HA 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-HA Series during operation.
• When the SJ-HA Series is used in an enclosed space, the generated ozone may become
harmful.
Make sure that there is adequate ventilation when using the SJ-HA Series in an enclosed
space.
• Do not use the SJ-HA 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-HA 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-HA 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-HA Series, immediately turn off the power and
contact the nearest KEYENCE office. Do not try to repair the SJ-HA Series by yourself.
This may cause electric shock or product malfunctions.
• Do not touch the SJ-HA Series' electrode probes with hard objects such as tools. If the
electrode probes are damaged, the SJ-HA Series does not operate properly, resulting in
product malfunctions.
• Operate the control panel of the SJ-HA Series with the flat-blade screwdriver provided
with the product.
• When mounting the SJ-HA Series, use the provided End units (L/R) and Auxiliary Support
Part, otherwise product malfunctions may result.
• When the SJ-HA 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-HA Series with dust accumulating on the electrode probes, the SJ-HA Series
will not operate properly, resulting in product malfunctions. Regular cleaning (about every
2 weeks) is recommended.
• Do not drop the SJ-HA Series or subject it to a strong impact. This may cause product mal-
functions.
• Do not use the SJ-HA Series for any purpose other than eliminating static electricity.
• When the SJ-HA 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-HA Series to malfunc-
tion. 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-HA unit or more than one SJ-
HA unit connected together, otherwise the power supplies will be short-circuited and prod-
uct malfunctions may result.
■ Precautions for grounding
The 10-pin I/O cable for the SJ-HA Series is provided with a ground wire.
• For proper static elimination, be sure to completely ground the SJ-HA Series' grounding
cable.
• The grounding cable must be grounded at a resistance not exceeding 100 Ω.
■ Warning labels on SJ-HA Series
For safety reasons, the warning labels are attached to the SJ-HA Series. Read each label carefully
and follow the instructions on the labels.
■ Locations
To prevent product malfunctions, avoid installing the SJ-HA Series in the following locations.
• Locations in which the SJ-HA 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-HA 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-HA 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.
• If the unit is turned off while setting, the settings may be damaged.
Before using the unit, wait approx. 20 minutes after the unit is turned on. Otherwise, the ion
balance may not be stabilized.
