carefully:
Before starting work
●Follow all the instructions and operating procedures provided in this manual and related manuals.
●Pay particular attention to the cautionary notes in the manuals and on the equipment itself, and comply with
their stipulations.
Failure to do so could cause personal injury or damage to the machine.
●Do not perform any operation or action that is not described in this manual. When in doubt, contact the
relevant store or your sales staff.
●The hazard warnings on the machine and in the manual cannot cover every possible case, as it is impossible
to predict and evaluate all circumstances.
You must be alert and use your common sense.
●Do not perform any installation, wiring, handling, or internal customization that is not described in this
manual. Hitachi will not be responsible for any damage to Hitachi equipment or peripherals and personal
injury resulting from such a practice.
●In case this product fails, configure an emergency stop circuit or interlock circuit outside the product. Failure
of this product might damage the machine or cause an accident.
●Maintenance work must be done only by appropriately trained persons who have practical experience and
understand the potential hazards (and how to avoid them) during operation.

S-3
During work
●Follow the sequence of steps specific to each procedure.
●Use the relevant tools and instruments for each task as specified in the manual. If no particular tools are
specified, use commercially available tools and instruments which fit the purpose.
●Make sure that all measurement instruments and powered tools have been properly calibrated or periodically
inspected prior to use.
●Keep the maintenance area neat and tidy.
●Make sure that maintenance parts, materials, and removed parts are not placed in a passageway so they are
not tripped on by personnel.
●Wear eye protection if there is a risk of flying debris.
●When using sharp objects or cutting tools, keep fingers and other parts of your body away from the path of
the blade bit or point.
●After maintenance work is completed, before turning on power, make sure that all parts removed during
maintenance have been installed back in their original positions in the machine. Also make sure that no tool
or foreign material remains in the machine.

S-4
Prevention of electric shock
●Before starting work, make sure that there is no potential electrical hazard in the maintenance area.
Example: Insufficient grounding line or a wet floor
●Before starting work, check the location of the emergency power-off switches and how to operate them.
●Unless otherwise specifically instructed, isolate the machine from all power sources before starting
maintenance. Turn off not only the power switches on the machine but also the switch on the distribution
panel.
After turning off the switch on the power distribution panel, attach a notice saying Do not turn on this switch
on the power distribution panel. If the power distribution panel is equipped with a lockout device, turn off the
switch on the power distribution panel, lock the device, and then bring the key with you.
If you are resuming maintenance work performed by someone else, do not assume that the power is off.
Make sure that the above-mentioned conditions, such as switches turned off, are satisfied. If necessary, use a
measurement tool to ensure that the power is off.
●Some parts in the machine remain charged for a certain time even after the power supply to the machine is
disconnected. (Follow the displayed instructions).
●When working on a machine which has a grounding terminal, make sure that the terminal is properly
connected to the facility's ground.
●When working near an exposed live electric circuit, do not work alone. Work with another person who can
immediately turn off the power.
●To prevent electric shock during work, do not wear any metallic items or an accessory such as a wristwatch
with a metallic surface. If you wear eyeglasses with a metallic frame, take care not to let the frame touch an
uninsulated surface.
●Make sure that your hands and arms are dry.
●Use only one hand when it is necessary to work near an exposed live electric circuit. This mitigates the risk
of current passing through your heart if you accidentally touch the circuit.
●Do not use a dental mirror near an exposed live electric circuit. The mirror surface is conductive and can
become hazardous even if the mirror is made of plastic.
●Unless otherwise specifically instructed, do not supply power to any subassembly such as a power supply
unit or a motor while it is removed from the machine.

S-5
Procedure in an emergency
In the case of electric shock
●Do not panic. Do not become another victim through contact with the injured person.
●First, shut off the electric current passing through the victim by using the emergency power-
off switch. If there
is no emergency power-off switch, use the normal power-off switch.
If this cannot be done, push the victim away from the source of the electric current by using a nonconductive
object such as a dry wooden stick.
●Call an ambulance.
●If the victim is unconscious, artificial respiration may be necessary.
A proper method for performing artificial respiration or resuscitation should be learned beforehand.
If the victim's heart is not beating, cardio-pulmonary resuscitation must be performed by a trained and
qualified person.
In the case of fire
●Call the fire department, and then take action to extinguish the fire.
●Shut off power to the machine by using the emergency power-off switch. If there is no emergency power-off
switch, use the normal power-off switch.

S-8
WARNING
●Do not allow the primary battery to be swallowed. Keep the battery out of reach of infants and children.
If the primary battery is inadvertently swallowed, immediately consult a physician.
●Do not attempt to charge the primary battery. Attempting to charge the battery can result in gas
generation or internal shorting, causing such issues as deformation, leakage, heat generation, explosion,
or fire.
●Do not heat the primary battery. If the battery is heated to a temperature of 100°C or higher, the internal
pressure of the battery rises, causing such issues as deformation, leakage, heat generation, explosion, or
fire.
●Do not place the primary battery in a fire. If you do so, the metallic lithium will melt, causing the
battery to explode or catch fire.
●Do not disassemble or bend the primary battery. Doing so can damage the insulating material, internal
structure, or other aspect of the battery, causing such issues as deformation, leakage, heat generation,
explosion, or fire.
●Take care not to insert the primary battery in the device upside down. Doing so can cause an abnormal
reaction such as charging or shorting of the battery, which can lead to issues like deformation, leakage,
heat generation, explosion, or fire.
●Do not allow a wire or other metallic object to contact the plus and minus terminals of the primary
battery. Also, do not store or carry the battery with a necklace, hairpin, or other metal object that might
cause such a connection to occur. Do not remove multiple batteries from their packaging and store them
stacked together. If the primary battery shorts out, a significant overcurrent might flow, causing such
issues as deformation, leakage, heat generation, explosion, or fire.
●Do not directly solder terminals or wires to the primary battery. The applied temperature can damage
the insulation or internal structure of the battery, causing such issues as deformation, leakage, heat
generation, explosion, or fire.
●Do not touch any liquid that has leaked from the primary battery. If the liquid contacts your eyes, it can
cause eye damage. If such contact occurs, flush your eyes thoroughly with plenty of water from the
faucet or another clean source, and immediately seek medical treatment. Do not rub your eyes. If the
liquid enters your mouth or adheres to your lips, gargle with plenty of water from the faucet or another
clean source, and consult a physician.
●Keep any liquids associated with the primary battery away from fire. If the battery is bent, leaking
liquid, or producing an unusual odor, the electrolytic solution that leaks from the battery has the
potential to ignite. Remove the battery from any source of fire.
●Do not keep the primary battery in prolonged contact with skin. Skin damage might result if tape or
other means is used to achieve prolonged skin contact.
●Do not use primary batteries other than those specified by Hitachi. Use of other primary batteries can
cause abnormal current to flow, causing damage to the primary battery or CPU module, or resulting in
heat generation, smoke, explosion, or fire.
(See page 14-6.)

S-9
WARNING
●Shorting the battery terminals is dangerous even for a drained battery. A short circuit might occur if
contact is made between the plus and minus terminals, or the battery contacts a piece of metal. When
disposing of primary batteries, use insulating tape to wrap each battery as shown in the following
example. Having done so, dispose of the battery as industrial waste.
Example of battery insulation:
(See page 14-7.)
●To avoid electric shock, turn off the power supply on the facility side that is connected to the PI/O
module before removing or mounting the module.

2.3 CAUTION
CAUTION
●Do not insert a finger or foreign object into the gap between a connector and the mount base. Doing so
might lead to injury or cause the system to malfunction.
●To avoid fire, use an external power supply with an overvoltage and overcurrent protection function.
●To avoid fire, if you see smoke or smell an unusual odor, turn off the power immediately and
investigate the source.
●Do not obstruct the ventilation slots at the top and bottom of the modules. Doing so might cause smoke
or fire, or lead to module failure or malfunction.
●The modules have open ventilation slots at the top and bottom. To avoid smoke, fire, and module failure
or malfunction, take the necessary measures to prevent objects from falling into the slots.(See page 1-5.)
●Do not insert a finger or foreign object into the gap between a connector and the mount base. Doing so
might lead to injury or cause the system to malfunction.
●Do not attach the mount base to the cabinet with modules already attached to the mount base. Doing so
might cause injury or module damage as a result of a module being dropped. (See page 6-6.)
●Make sure that the screws are securely tightened. Failing to do so can cause smoke, fire, or malfunction,
or cause the module to fall. (See pages 6-8 and 12-3.)
●Do not allow ultrasonic wave vibration near the primary battery. Ultrasonic wave vibration can
pulverize its contents, causing an internal short. This can lead to issues as deformation, leakage, heat
generation, explosion, or fire.
●Do not handle the primary battery roughly. Do not drop the battery, subject it to shock, or cause it to
deform. This can cause deformation, leakage, heat generation, explosion, or fire.
●Take care to avoid shorting the primary battery when inserting it into the device. Some devices might
have metal parts near where the battery is inserted, which can come into contact with the plus and minus
terminal of the battery.
●Do not use or leave the primary battery in direct sunlight, in a hot car, or any other location that
experiences high temperatures. This can cause deformation, leakage, heat generation, explosion, or fire.
●Do not allow the primary battery to get wet. This can cause deformation, leakage, heat generation,
explosion, or fire. It can also cause the battery to rust.
●Do not store the primary battery anywhere hot or humid. Doing so can reduce the performance or
service life of the battery. In some circumstances, it can also cause deformation, leakage, heat
generation, or explosion.
(See page 14-7.)

S-11
2.4 Notice
Notice
●There is a potential for failure if PCs are not installed in a waterproof cabinet.
●Static electricity might damage a module or cause it to malfunction. Discharge any static electricity
from your body before touching the equipment.
●The system is not designed to withstand constant vibration or shock. If the system is installed in a
location subject to such conditions, isolate the system from sources of vibration or shock, or take anti-
vibration measures such as the use of anti-vibration rubber mounts.
(See page 1-1.)
●The cabinet in which the CPU and PI/O modules of the S10VE are mounted must have ventilation holes
in the door and top panel, or have a fan installed in the door. To improve airflow within the cabinet,
make sure that there are gaps at the top, bottom, and sides of each mount base. Failing to provide these
gaps might lead to module failure or malfunction.
●To avoid failure and malfunction, consider the following measures during installation design to ensure
that the intake air temperature at the center of the base of the power supply module and CPU modules
does not exceed 55°C:
- Make sure there is plenty of space between a unit and those above and below it
- Use a fan to perform forced air cooling
- Install a waste heat duct
- Install a cooler for the control panel
●To prevent equipment damage during transport, protect the equipment with cushioning material and
transport it as you would a precision instrument.
(See page 1-5.)

S-12
Notice
●In remote I/O communication, there is no way to view error information besides checking the system
register and looking at the LED indicators on the station module and remote I/O optical adapter. There
is no way to determine from the contents of the received data whether the data was transmitted normally
or a time out occurred. This means that in a large-scale or wide area system that has been built using
remote I/O optical adapters, it takes a long time to analyze the cause when an issue arises. Because the
system register and LED indicators provide current status information, the operator can identify the
source of a persistent error, such as that caused by a failed module. However, identifying the source of
an error that manifests intermittently such as a partial cable disconnection takes much more time.
Given this difficulty in identifying the source of errors related to remote I/O communication, you must
keep the following in mind with the objective of streamlining the process of failure analysis when a
failure occurs:
A module such as OD.RING makes it easier to analyze faults on a line. Consider using it in your system
design where doing so is cost-effective.
-Design the system in a way that considers fault analysis, through such means as centralized installation
and PI/O unit aggregation.
- Prepare an allocation table that shows the correspondence of I/O signals and PI/O addresses with
respect to the entire system configuration. This allows you to identify the location of the fault when an
issue with data occurs at the application level, such as data not being updated due to a timeout.
-The CPU module of the S10VE system does not perform external notification if the remote I/O line
times out. It is the responsibility of the user to use a program that monitors the system register at the
control cycle level and identifies when a timeout occurs.
- To identify the source of an intermittent fault, it is the responsibility of the user to use a program that
saves to memory all areas of the system register related to the remote I/O line when a timeout occurs.
- Tag each optical cable with its line number to prevent incorrect connection of the remote I/O optical
adapter and optical cables.
●If multiple remote I/O optical adapters are installed together, turning off the power supply module of the
CPU unit for maintenance of the remote I/O optical adapter prevents any further remote I/O
communication that involves the remote I/O optical adapters. When designing the system, consider your
maintenance procedures when implementing remote I/O optical adapters.
(See pages 2-4 and 13-87.)
●To prevent damage to the power supply module, take the following precautions:
- Leave sufficient time (at least 5 seconds) between turning the power switch off and on.
- Do not repeatedly turn the power switch on and off.
- Input voltage must increase and decrease monotonically between 0 and 85V.
- Do not supply a fluctuating input voltage that might cause the power supply module to repeatedly start
and stop.
(See page 5-4.)

S-13
Notice
●If the environment does not meet the conditions for grounding to the steel frame of the building, drive a
grounding rod in the earth near the PCs panel that provides a low grounding resistance. This prevents
surrounding noise from entering the PCs and prevents equipment from failing or malfunctioning.
Conditions for grounding to steel frame of building:
- The steel frame is welded together.
- The grounding between the earth and the steel frame meets the criteria for class D.
- To prevent AC current from entering the grounding point of the PCs panel, the grounding point
connects to a different main line from the AC panel, separated by a distance of at least 15 m.
(See page 6-1.)
●To avoid failure or malfunction, leave clearance of at least 100 mm between the cabinet (top and bottom
panels) and unit, and between each unit. If you are unable to provide 100 mm of clearance, make sure
that the intake air temperature will not exceed 55°C.
●To avoid failure or malfunction, leave clearance of at least 50 mm between the cabinet (side panels) and
units. If you are unable to provide 50 mm of clearance, make sure that the intake air temperature will
not exceed 55°C.
(See page 6-4.)
●Secure the mount base to the upright surface inside the cabinet. The rise in temperature that occurs
when the mount base is attached anywhere else can damage or degrade the equipment.
●To avoid malfunction, do not remove the insulating bushes that insulate the mount base from the
cabinet. Confirm that the structure does not allow the metallic part of the mount base to contact the
control panel.
●The system is not designed to withstand constant vibration or shock. If the system is installed in a
location subject to such conditions, isolate the system from sources of vibration or shock, or take anti-
vibration measures such as the use of anti-vibration rubber mounts.
(See page 6-6.)

S-14
Notice
●Static electricity might damage a module or cause it to malfunction. Discharge any static electricity
from your body before touching any equipment.
●Poor contact might cause malfunction. Mount the module and connect cabling to the module
immediately after the module is unpacked so that dust or other foreign substances do not accumulate on
connectors.
●To avoid damaging a module when removing or mounting it, turn off the power switch of the power
supply module beforehand.
●To avoid damaging a module, observe the following precautions when mounting or removing the
module:
- Before mounting the module on the mount base connector, check that the connector pins are properly
aligned and not bent, broken, or soiled.
- Connecting or disconnecting a module that is tilted might damage connector pins. When moving the
module, hold it vertically parallel to the mount base as shown below.
(See page 6-8.)
●Mounting a module to the wrong slot can damage the equipment. Mount the power supply module,
CPU module, and RI/O-IF module to its dedicated slot and no other.
(See page 6-10.)
●Failing to observe the PI/O module mounting restrictions can lead to malfunction.
(See page 6-13.)

S-15
Notice
●The grounding system of the CPU unit differs from that of the PI/O unit. To avoid malfunction or
damage to a module, confirm that the wiring is correct.
(See page 7-8.)
●Noise can cause the system to malfunction. Make sure that the protective grounding terminal ( ) is
grounded.
●To avoid malfunction, the mount base must be insulated from the cabinet. Do not remove the insulating
bushes from behind the mount base.
●Connect the FG terminals of adjacent modules and mount base in a daisy chain, and then connect the
end of the daisy chain to the FG terminal of the power supply module.
●Do not connect the FG terminal of a module to a mount base fixing screw.
(See page 7-9.)
●To avoid malfunction, set a terminating resistance (150Ω) at any RI/O-IF module ports to which a
remote I/O cable will not be connected. This prevents external noise from entering the system.
(See pages 7-14 and 7-15.)
●Noise can cause malfunction. Do not harness the wiring for 100 V AC or 100 V DC power together
with network cables. There must be at least 100 mm separation between the two types of cabling.
●To protect from short circuits, provide fuses or circuit protectors in any external power source. Use a
circuit protector that is appropriate for the rating of the system.
●Surge voltage can cause equipment damage or malfunction. If you connect a coil (such as a relay) to the
PCsOK output circuit, you must also provide a surge absorption diode or other means to protect from
surge voltage. This diode must withstand reverse voltage of at least 10 times the circuit voltage, and a
forward current matching or exceeding the load current.
●Noise can cause the equipment to malfunction. Keep each type of cable, such as communication cables,
power cables, and lead cables separated when wiring the system. It is of particular importance that lead
cables such as those for inverters, motors, and power regulators are separated from other cables by at
least 300 mm. Furthermore, communication cables must travel through different conduits and ducts
from lead cables.
●Static electricity might damage a module or cause it to malfunction. Discharge any static electricity
from your body before touching the equipment.
●To avoid malfunction, set a terminating resistance (150Ω) at any RI/O-IF module ports to which a
remote I/O cable will not be connected. This prevents external noise from entering the system.
(See page 7-19.)
