SAFETY PRECAUTIONS
Be sure to read this manual and all other attached documents carefully before installing, operating
inspecting or conducting maintenance on this unit. Always use this unit properly. Be sure to
carefully read the information about the device, the safety information and precautions before using
this unit. Be sure that the person(s) responsible for maintenance receives and understands this
manual completely.
This manual divides the safety precautions into DANGERs and CAUTIONs.
: Failure to observe these warnings may result in death or serious injury.
: Failure to observe these cautions may result in injury or property damage.
Failuretoobserveany may lead to serious consequences.
All of these DANGERs and CAUTIONs provide very important precautions and should always be
observed.
Additional safety symbols representing a prohibition or a requirement are as follows:
: Prohibition. For example, “Do not disassemble” is represented by:
: Requirement. For example, if a ground is required, the following will be shown:
DANGER
CAUTION
CAUTION

DANGER
 Devise an emergency stop circuit, interlock circuit, and other similar circuits
outside the programmable controller. Disregarding this rule may result in
damage to the equipment or cause an accident if the programmable controller
fails.
 Keep it in mind that this hardware unit operates on a high voltage. If the user
touches a high-voltage terminal inadvertently during connection or disconnection
of this hardware unit or its cable, he or she may suffer from an electric shock.
Also, this hardware unit may be damaged due to a short circuit or noise. Be
sure to switch off the hardware unit before connecting or disconnecting it or its
cable.
CAUTION
 This hardware unit may fail if the ambient temperature is too high. The
hardware unit may also malfunction due to interference by electromagnetic
waves from adjacent hardware. To dissipate heat and reduce electromagnetic
interference, provide the specified mount of space between the cubicle and this
hardware unit and between the hardware unit and other ones.
 After installing this hardware unit, measure temperatures near the in-cubicle
controller and the mount base during operation, and check whether the
measurements are within the limits. If the specified amount of space cannot be
provided or the measured temperature is too high, use a cooling fan.
 At an extremely high temperature, this hardware unit may fail. Secure the
mount base to a vertical surface. If the mount base is secured horizontally, heat
does not dissipate efficiently, resulting in an extremely high temperature. This
may further cause the hardware unit to fail or its parts to deteriorate.
 This hardware unit may be damaged due to static electricity. Ground yourself
before setting switches or connecting or disconnecting cables or connectors with
the hardware unit.
 This hardware unit may be damaged during its installation or removal unless the
following rules are observed:
• Check that the connector pins are not damaged (bent or broken), are aligned
straight and are free from dust.
• Move the hardware unit along an imaginary vertical surface to the face of the
mount base. If the product is inserted or removed slantwise from the
connector on the mount base, connector pins may be bent.

REQUIREMENT
 An electric shock may lead to a death or burn. Noise may cause the system to
malfunction. Ground the line ground (LG), frame ground (FG), and shield (SHD)
terminals, as described below.
• Electrically insulate the mount base from the cubicle. To assure this, do not
remove the insulating sheet from the mount base.
• Ground the LG and FG terminals separately to prevent mutual interference.
The LG terminal is grounded to prevent intrusion of power line noise, while FG
and SHD terminals are grounded to suppress intrusion of line noise into
external interfaces for remote I/O modules, interface modules, and other
modules.
• Connect the FG terminal on each module to the FG terminal on the mount
base. Note, however, that the FG terminal for each remote I/O line or JPCN-1
line must be connected separately to a single place on the terminating side.
REQUIREMENT
 Excessive accumulation of heat in the cubicle may cause a fire or hardware
failure. When the temperature in the cubicle reaches 48°C or higher, the
maximum output current of the power supply module is limited. At 55°C, for
instance, it is limited to 5.85 A. Where this is very likely, install a cooling fan in
the cubicle or reduce the number of modules installed therein.
PROHIBITION
 If a part in a module is damaged, do not replace the part, but replace the faulty
module in its entirety, except when the part is the battery for the CPU.

Installation
The Programmable Controller is not fireproof, dustproof, or dripproof. When you install, mount
the controller in a dust and dripproof iron cubicle as shown below:
Iron cubicle
CPU unit
I/O unit
Fill this opening with putty.
Figure 1-1 Installation Example

Environment
Operate the Programmable Controller in the following environment:
Table 1-1 Operating Environment
Supply voltage 100 to 120 VAC, single-phase, 50/60 Hz±4%
Amplitude range 85 to 132 VAC
Temperature At operation: 0 to 55°C; storage: -20 to 75°C
Relative humidity At operation: 30 to 90% RH; storage: 10 to 90% RH
Vibration resistance 0.6 G (1000 rpm)
Shock resistance 10 G
Ambient air Dust: 0.1 mg/m3or less (given that there is no corrosive gas)
Output module
Furnish the output module load power supply with a fuse for the protection of load short-circuits.
Ensure that the employed fuse is rated to match the load. If the employed fuse rating is higher
than specified, the printed circuit boards, case, and other items may burnout when the load is
shorted.

Grounding point
Provide Class D* or better independent grounding. Do not use any other existing ground as a
substitute. It is particularly important that the grounding point for the Programmable Controller
be at least 15 m away from an AC panel grounding point.
* Class D grounding is defined in the Technical Standard for Electrical Facilities of Japan. This
standard states that the grounding resistance must be 100 ohms or less for equipment operating
on 300 VAC or less, and 500 ohms or less for devices that shut down automatically within 0.5
seconds when shorting occurs in low tension lines.
It is the best that the grounding wire be welded to the steel frame of a building. In case when
the aforesaid is impossible, bury the grounding rod in earth.

LG ground
Keep at least 15 meters between

and the AC panel.

Noise
Do not install the Programmable Controller inside or near a panel on which a high-voltage device
such as inverter is mounted. Make a shielding plate to protect the CPU or I/O unit main frames
and cables from electromagnetic or electrostatic induction.
External circuitry
Partial damage may affect the entire circuitry of the Programmable Controller. Ensure that the
emergency stop circuit incorporated in the Programmable Controller consists of an external relay
circuit.

Internal parts replacement
User must not replace internal parts of the Programmable Controller with anything other than the
parts specified in the manual. Replace the entire module in which a defective part is included.
For details on parts replacement, contact your Hitachi maintenance personnel.
Module insertion/removal
Power must be turned off while a module is inserted or removed. Insertion or removal of a
module when power is ON may cause damage to the module or electric shock.
Equipment addition
If the peripheral equipment is added or altered, conduct an inspection as directed in Section 7.1,
"Preventive Maintenance" to confirm whether the Programmable Controller is properly
functioning.
Special attention must be paid to the following regarding power supply and grounding.
zPower supply
* Inspection of the supply voltage and waveform.
−Check for a voltage reduction.
−Check for a significance in the amount of noise in the power supply line.

zGrounding
* Inspection of the ground wiring.
−Check if a ground wire is shared with another ground wire.
−Check if the grounding point is at least 15 m away from the grounding point of the AC
panel.
* Check if any power supplies or power cables are located adjacent to the signal cables such
as line.
