1. Installation Precautions
REQUIREMENT
Fasten the mount base to a vertical surface. Fastening the mount base to a
horizontal surface lessens the heat dissipation effects and allows the
temperature to rise, thereby rendering the module defective or incurring
component parts deteriorati on.
Before installing the module, discharge any static buildup from your body
because static electricity may render the module defective.
Properly tighten the screws. If they are inadequately tightened, malfunction,
smoke emission, or combustion may occur.
DANGER
If an emergency stop circuit, interlock circuit, or similar circuit is to be
formulated, it must be positioned external to this module. If you do not
observe this precaution, equipment damage or accident may occur when this
module becomes defective.
Ensure that the employed external power source has overvoltage and
overcurrent protection functions.
The external power source voltage may create an electric shock hazard. If
you disconnect/connect the module or cable with the power supply switched
on, you may inadvertently touch a power supply terminal and receive an
electric shock or the equipment may become damaged due to short circuit or
noise. Switch off the power supply before disconnecting/connecting the
module or cable.
CAUTION
Use the module in an environment specified in the catalog and manual.
If you use the module in an environment where the module is subjected to high
temperature, high humidity, dust, corrosive gas, vibration, or impact, a risk of
electric shock, fire, or malfunction may result .
Observe the installation procedure stated in the manual.
If the module is improperly installed, it may drop, become defective, or
malfunction.
Do not allow wire cuttings or other foreign matter to enter the module.
The entry of foreign matter in the module may result in a fire or cause the
module to become defective or malfunction.
When the module is to be positioned at a location wher e it may become wet
with water, place it within a drip-proof enclosure to prevent it from becoming
defective.
CAUTION
The module may become defective due to a high temperature, which may
result from heat dissipation failure. It may also mal functi on du e to
electromagnetic interfer ence fro m nearby equipment. For heat dissipation
and electromagnetic radiation minimization, provide the specified clearances
among the module, its enclosure, and neighboring equipment.
The degree of temperature rise varies depending on how the module is
mounted. The mounting intervals specified in the manual should be used as
a guide only. While a test run is conducted after completion of mounting,
measure the temperature near the module to check whether it is within the
specified range. If the measured temperature is beyond the specified range,
increase the mounting intervals or provide forced air cooling with a cooling fan.
Dust or other foreign matter might accumulate on the connector, resulting in
poor contact. Immediately after the module is unpacked, perform the
mounting and wiring procedures.
To prevent the module from being dam ag ed, obser v e the foll owing precautions
when you mount or demount the module:
• Before mounting the module to the mount base connector, check that the
connector pins are properly aligned and not bent, broken, or soiled with dirt
or the like.
• Ensure that the module is parallel to the mount base vertical surface as
shown below when mounting. If you connect a module to or disconnect it
from its connector while it is tilted, the connector pins may become damaged.
Mount base
［Bad example］
Module
［Good example］
PROHIBITION
Do not take the insulation sheets off the mount base. These insulation sheets
electrically insulate the modules from the mount base.
PROHIBITION
Do not disassemble or modify the module. Failure to observe this precaution
may result in a fire or cause the module to become defective or malfunction.
2. Wiring Precautions
REQUIREMENT
To provide protection against short circuit, furnish the external power source
with a fuse or circuit protector. Ensure that the employed circuit protector is
rated as specified.
Before supplying power to the equipment, thoroughly check the wiring
connections.
Surge voltage may cause malfunction or damage to this product. When you
connect coils, such as relays, to the PCsOK output circuit, be sure to add
surge-absorbing diodes or the equivalent to that circuit. The peak reverse
voltages of these diodes must be at least 10 times as high as the circuit
voltage and their forward currents must be larger than the load current.
Before making power supply wiring connections, make sure that no voltage is
applied to the power cable. Immediately after completion of power supply
wiring, be sure to install the terminal cover.
Ensure that the communication, power supply, motive power, and other cables
are routed apart from each other. It is essential that the inverter, motor,
power regulator, and other motive power cables be routed at least 300 mm
away from the other types of cables. Also, be sure that the communication
and motive power cables are routed within separate conduits.
DANGER
Electric shock hazards exist so that you might suffer burns or become
electrocuted. Further, the system might malfunction due to noise interference.
Therefore, ground the line ground (LG), frame ground (FG), and shield cable
(SHD).
REQUIREMENT
Insulate the mount base from the enclosure. To keep the mount base
insulated, avoid removing the insulation sheets that are supplied with the
mount base.
The LG is a ground terminal for power supply noise. The FG and SHD are
ground terminals for the noise in the remote I/O, communication module and
other external interface lines. To avoid interference between the ground
terminals, separately ground the LG and FG.
Connect each module's FG terminal to the FG terminal provided on the mount
base and ground those terminals properly. The FG terminals for remote I/O
lines and JPCN-1 (J.NET or IR.LINK) lines must be grounded at one place
(LPU unit) for each line -- the FG terminals of remote I/O station and JPCN-1
station (J.Station or IR.Station) modules that can be grounded at the same
place as is the LPU unit must all be grounded.
CAUTION
If the input voltage for the power supply module is within the specified range
but close to the upper or lower limit, you should conclude that an input power
problem exists, and ask the power supply facility manager to conduct an
inspection.
Be sure that the power source for supplying power to various modules is rated
as specified. The use of a differently rated power source may cause a risk of
fire.
Ensure that the same power source is used for output module external power
source (for supplying power to the +V terminal) and load power supply. The
use of different power sources may cause a risk of malfunction.
Only qualified personnel should be allowed to make cable connections.
Incorrect wiring connections may cause a risk of fire, malfunction, or electric
shock.
PROHIBITION
To avoid noise-induced malfunction, do not bundle the 100 VAC/100 VDC wiring
and network cable together, but route them at least 100 mm away from each
other.
3. Operating Precautions
REQUIREMENT
Before terminating this product (by shutting down or resetting), check that all
the peripheral equipment is already stopped or will not be affected by the
termination.
Failure of an installed module may damag e the contents of memory spaces.
Be sure to make a backup copy of any important data in memory.
Overheating may cause a fire or unit failure. Where the ambient temperature
reaches 48°C or higher, lower the maximum output current that can be drawn
from the power supply module. By taking into consideration the environment
where the unit is mounted, install a cooling fan in the housing enclosure or
reduce the number of modules mounted.
DANGER
The input/output currents of I/O modules must be within their maximum
allowable current values. If an overcurrent flows in the I/O module, its
component parts may be damaged, r esulti ng i n an accident, fir e , or fail ure.
If the module emits smoke or foreign odor, immediately switch off the power
supply and investigate the problem cause.
While the power is applied, never touch a terminal strip or connector pin. If
you touch a terminal strip or connector pin while the power is applied, you may
receive an electric shock.
CAUTION
Before changing the program, generating a forced output, or performing the
RUN, STOP, or like procedure during an operation, thoroughly verify the safety
because the use of an incorrect procedure may cause equip ment d amag e or
other accident.
When you switch on the power supply, follow the specified power-on
sequence. Failure to follow the specified sequence may cause equipment
damage or other accident.
CAUTION
Do not use a transceiver, cellular phone, or similar device near the unit
because unit malfunction or system failure may occur due to noise.
The parts, which used gallium arsenic (GaAs) for a photo coupler and LED, are
included in this product. GaAs is specified as a harmful object by law. Take
special care when handling the product, in particular, scrapping it. Before
scrapping the product, ask a professional waste disposal dealer in charge of
scrapping work.
To avoid malfunction, ensure that the power supply is switched on and off at
intervals of longer than 1 second.
PROHIBITION
Do not carry out any installation, wiring, handling, and remodeling not covered
in this manual. The manufacturer is not liable to any damage to the product
and peripheral equipment and/or bodily injury due to such an improper
practice.
Never insert your finger or foreign matter into the gap between a connector
and the mount base. Disregarding this rule may result in a bodily injury..

1 PRELIMINARY CHECKING
Is grounding correct?
• Do not ground the D.NET module in the same place where high-voltage equipment is grounded.
They must be grounded in separate places.
• Perform grounding work conforming to Class D* or higher grounding standard.
Are the LG and FG separated?
• Be sure to separate the LG from the FG or vice versa because power noise enters the FG via the
LG. Failure to observe this rule may result in an equipment malfunction.
• Ground the LG at the power supply side.

LG is here!
FG is over there!
* 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.
