conditions, resulting in death or severe injury.
Indicates that incorrect handling may cause hazardous
conditions, resulting in minor or moderate injury and/or
property damage.
CAUTION level instructions
Under some circumstances, failure to observe the
may also lead to serious results.
Be sure to observe the instructions of both levels to ensure the safety.
Please keep this manual in a safe place for future reference and also pass this
manual on to the end user.
[DESIGN PRECAUTIONS]
DANGER
z Create a safety circuit outside the PLC to ensure the whole system will operate
safely even if an external power failure or a PLC failure occurs.
Otherwise, incorrect output or malfunction may cause an accident.
(1) For an emergency stop circuit, protection circuit and interlock circuit that is
designed for incompatible actions such as forward/reverse rotation or for
damage prevention such as the upper/lower limit setting in positioning,
any of them must be created outside the PLC.
A-1
[DESIGN PRECAUTIONS]
DANGER
(2) When the PLC detects the following error conditions, it stops the
operation and turn off all the outputs.
y The overcurrent protection device or overvoltage protection device of
the power supply module is activated.
y The PLC CPU detects an error such as a watchdog timer error by the
self-diagnostics function.
In the case of an error of a part such as an I/O control part that cannot be
detected by the PLC CPU, all the outputs may turn on. In order to make
all machines operate safely in such a case, set up a fail-safe circuit or a
specific mechanism outside the PLC.
Refer to "LOADING AND INSTALLATION" in this manual for example fail
safe circuits.
(3) Depending on the failure of the output module’s relay or transistor, the
output status may remain ON or OFF incorrectly. For output signals that
may lead to a serious accident, create an external monitoring circuit.
y If load current more than the rating or overcurrent due to a short circuit
in the load has flowed in the output module for a long time, it may cause
a fire and smoke. Provide an external safety device such as a fuse.
y Design a circuit so that the external power will be supplied after
power-up of the PLC.
Activating the external power supply prior to the PLC may result in an
accident due to incorrect output or malfunction.
y For the operation status of each station at a communication error in
data link, refer to the respective data link manual.
The communication error may result in an accident due to incorrect
output or malfunction.
A-2
[DESIGN PRECAUTIONS]
DANGER
z When controlling a running PLC (data modification) by connecting a peripheral
device to the CPU module or a PC to a special function module, create an
interlock circuit on sequence programs so that the whole system functions
safely all the time.
Also, before performing any other controls (e.g. program modification,
operating status change (status control)), read the manual carefully and
ensure the safety.
In these controls, especially the one from an external device to a PLC in a
remote location, some PLC side problem may not be resolved immediately
due to failure of data communications.
To prevent this, create an interlock circuit on sequence programs and establish
corrective procedures for communication failure between the external device
and the PLC CPU.
z When setting up the system, do not allow any empty slot on the base unit.
If any slot is left empty, be sure to use a blank cover (AG60) or a dummy
module (AG62) for it.
When using the extension base unit, A52B, A55B or A58B, attach the included
dustproof cover to the module in slot 0.
Otherwise, internal parts of the module may be flied in the short circuit test or
when an overcurrent or overvoltage is accidentally applied to external I/O
section.
CAUTION
z Do not install the control lines or communication cables together with the main
circuit or power lines, or bring them close to each other.
Keep a distance of 100mm (3.94inch) or more between them.
Failure to do so may cause malfunctions due to noise.
z When an output module is used to control the lamp load, heater, solenoid
valve, etc., a large current (ten times larger than the normal one) may flow at
the time that the output status changes from OFF to ON. Take some
preventive measures such as replacing the output module with the one of a
suitable current rating.
A-3
[INSTALLATION PRECAUTIONS]
CAUTION
z Use the PLC under the environment specified in the user’s manual.
Otherwise, it may cause electric shocks, fires, malfunctions, product
deterioration or damage.
z Hold down the module loading lever at the module bottom, and securely insert
the module fixing latch into the fixing hole in the base unit.
Incorrect loading of the module can cause a malfunction, failure or drop.
When using the PLC in the environment of much vibration, tighten the module
with a screw.
Tighten the screw in the specified torque range. Undertightening can cause a
drop, short circuit or malfunction. Overtightening can cause a drop, short circuit
or malfunction due to damage to the screw or module.
z Connect the extension cable to the connector of the base unit or module.
Check the cable for incomplete connection after connecting it.
Poor electrical contact may cause incorrect inputs and/or outputs.
z Correctly connect the memory cassette installation connector to the memory
cassette. After installation, be sure that the connection is not loose. A poor
connection could cause an operation failure.
z Be sure to shut off all phases of the external power supply used by the system
before mounting or removing the module. Failure to do so may damage the
module.
z Do not directly touch the conductive part or electronic components of the
module.
Doing so may cause malfunctions or a failure of the module.
A-4
[WIRING PRECAUTIONS]
DANGER
z Be sure to shut off all phases of the external power supply used by the system
before wiring.
Failure to do so may result in an electric shock or damage of the product.
z Before energizing and operating the system after wiring, be sure to attach the
terminal cover supplied with the product.
Failure to do so may cause an electric shock.
CAUTION
z Always ground the FG and LG terminals to the protective ground conductor.
Failure to do so may cause an electric shock or malfunctions.
z Wire the module correctly after confirming the rated voltage and terminal
layout.
Connecting a power supply of a different voltage rating or incorrect wiring may
cause a fire or failure.
z Do not connect multiple power supply modules to one module in parallel.
The power supply modules may be heated, resulting in a fire or failure.
z Press, crimp or properly solder the connector for external connection with the
specified tool.
Incomplete connection may cause a short circuit, fire or malfunctions.
z Tighten terminal screws within the specified torque range. If the screw is too
loose, it may cause a short circuit, fire or malfunctions.
If too tight, it may damage the screw and/or the module, resulting in a short
circuit or malfunctions.
z Carefully prevent foreign matter such as dust or wire chips from entering the
module.
Failure to do so may cause a fire, failure or malfunctions.
z Install our PLC in a control panel for use.
Wire the main power supply to the power supply module installed in a control
panel through a distribution terminal block.
Furthermore, the wiring and replacement of a power supply module have to be
performed by a maintenance worker who acquainted with shock protection.
(For the wiring methods, refer to Type A1N/A2N(S1)/A3NCPU User’s Manual.)
A-5
[STARTUP AND MAINTENANCE PRECAUTIONS]
DANGER
z Do not touch any terminal during power distribution.
Doing so may cause an electric shock.
z Properly connect batteries. Do not charge, disassemble, heat or throw them
into the fire and do not make them short-circuited and soldered. Incorrect
battery handling may cause personal injuries or a fire due to exothermic heat,
burst and/or ignition.
z Be sure to shut off all phases of the external power supply used by the system
before cleaning or retightening the terminal screws or module mounting
screws.

3. EMC DIRECTIVES AND LOW VOLTAGE DIRECTIVES
The products sold in the European countries have been required by law to comply
with the EMC Directives and Low Voltage Directives of the EU Directives since 1996
and 1997, respectively.
The manufacturers must confirm by self-declaration that their products meet the
requirements of these directives, and put the CE mark on the products.
3.1 Requirements for Compliance with EMC Directives
The EMC Directives specifies emission and immunity criteria and requires the
products to meet both of them, i.e., not to emit excessive electromagnetic
interference (emission): to be immune to electromagnetic interference outside
(immunity).
Guidelines for complying the machinery including MELSEC-A series PLC with the
EMC Directives are provided in Section 3.1.1 to 3.1.6 below.
The guidelines are created based on the requirements of the regulations and
relevant standards, however, they do not guarantee that the machinery constructed
according to them will not comply with the Directives.
Therefore, the manufacturer of the machinery must finally determine how to make it
comply with the EMC Directives: if it is actually compliant with the EMC Directives.

3.1.1 EMC standards
When the PLC is installed following the directions given in this manual its EMC
performance is compliant to the following standards and levels as required by the
EMC directive.

3.1.2 Installation instructions for EMC Directive
The PLC is open equipment and must be installed within a control cabinet for
use.* This not only ensures safety but also ensues effective shielding of
PLC-generated electromagnetic noise.
* : Also, each network remote station needs to be installed inside the control panel.
However, the waterproof type remote station can be installed outside the control
panel.
(1) Control cabinet
(a) Use a conductive control cabinet.
(b) When attaching the control cabinet's top plate or base plate, mask
painting and weld so that good surface contact can be made between
the cabinet and plate.
(c) To ensure good electrical contact with the control cabinet, mask the
paint on the installation bolts of the inner plate in the control cabinet so
that contact between surfaces can be ensured over the widest possible
area.
(d) Earth the control cabinet with a thick wire so that a low impedance
connection to ground can be ensured even at high frequencies.
(e) Holes made in the control cabinet must be 10 cm (3.94 in.) diameter or
less. If the holes are 10 cm (3.94 in.) or larger, radio frequency noise
may be emitted.
In addition, because radio waves leak through a clearance between the
control panel door and the main unit, reduce the clearance as much as
practicable.
The leakage of radio waves can be suppressed by the direct application
of an EMI gasket on the paint surface.
Our tests have been carried out on a panel having the damping
characteristics of 37 dB max. and 30 dB mean (measured by 3 m
method with 30 to 300 MHz).
(2) Connection of power and earth wires
Earthing and power supply wires for the PLC system must be connected as
described below.
(a) Provide an earthing point near the power supply module. Earth the
power supply's LG and FG terminals (LG: Line Ground, FG: Frame
Ground) with the thickest and shortest wire possible. (The wire length
must be 30 cm (11.81 in.) or shorter.) The LG and FG terminals function
is to pass the noise generated in the PLC system to the ground, so an
impedance that is as low as possible must be ensured. In addition, make
sure to wire the ground cable short as the wires are used to relieve the
noise, the wire itself carries large noise content and thus short wiring
means that the wire is prevented from acting as an antenna.
(b) The earth wire led from the earthing point must be twisted with the power
supply wires. By twisting with the earthing wire, noise flowing from the
power supply wires can be relieved to the earthing. However, if a filter is
installed on the power supply wires, the wires and the earthing wire may
not need to be twisted.
11
3.1.3 Cables
The cables pulled out of the control panel contain a high frequency noise
component. On the outside of the control panel, therefore, they serve as
antennas to emit noise.
Ensure to use shielded cables for the cables, which are connected to the I/O
modules, special modules and those pulled out to outside of the control panel.
Mounting ferrite core is not required except some types of CPU however, noise
emanated via the cable can be restrained using it.
The use of a shielded cable also increases noise resistance. The signal lines
(including common line) connected to the PLC input/output modules and
intelligent modules use shielded cables to assure noise resistance, as a
condition, standardized on EN61131-2/A12(2000).
If a shielded cable is not used or not earthed correctly, the noise resistance will
be less than the rated value
(1) Earthing of shielded of cables
(a) Earth the shield of the shielded cable as near the unit as possible taking
care so that the earthed cables are not induced electromagnetically by
the cable to be earthed.
(b) Take appropriate measures so that the shield section of the shielded
cable from which the outer cover was partly removed for exposure is
earthed to the control panel on an increased contact surface. A clamp
may also be used as shown in the figure below. In this case, however,
apply a cover to the painted inner wall surface of the control panel which
comes in contact with the clamp.

Note) The method of earthing by soldering a wire onto the shield section of
the shielded cable as shown below is not recommended. The high
frequency impedance will increase and the shield will be ineffective.

(2) MELSECNET (II) and MELSECNET/10 units
(a) Use a double-shielded coaxial cable for the MELSECNET unit which
uses coaxial cables. Noise in the range of 30 MHz or higher in radiation
noise can be suppressed by the use of double-shielded coaxial cables
(Mitsubishi Cable: 5C-2V-CCY). Earth the outer shield to the ground.
The precautions on shielding to be followed are the same as those
stated in item (1) above.

(b) Ensure to attach a ferrite core to the double-shielded coaxial cable
connected to the MELSECNET unit. In addition, position the ferrite core
on each cable near the outlet of the control panel. TDK-make ZCAT3035
ferrite core is recommended.
(3) Ethernet module
Precautions to be followed when AUI cables and coaxial cables are used
are described below.
(a) Ensure to earth also the AUI cables connected to the 10BASE5
connectors of the A1SJ71QE71-B5. Because the AUI cable is of the
shielded type, as shown in the figure below, partly remove the outer
cover of it, and earth the exposed shield section to the ground on the
widest contact surface.

(b) Use shielded twisted pair cables as the twisted pair cables*1 connected
to the 10BASE-T connectors. For the shielded twisted pair cables, strip
part of the outer cover and earth the exposed shield section to the
ground on the widest contact surface as shown below.
Shielded twisted pair cables

(4) I/O and other communication cables
For the I/O signal lines (including common line) and other communication
cables (RS-232, RS-422, etc), if extracted to the outside of the control panel,
also ensure to earth the shield section of these lines and cables in the same
manner as in item (1) above.

3.1.5 Ferrite core
Use of ferrite cores is effective in reducing the conduction noise in the band of
about 10 MHz and radiated noise in 30 to 100 MHz band.
It is recommended to attach ferrite cores when the shield of the shielded cable
coming out of control panel does not work effectively, or when emission of the
conduction noise from the power line has to be suppressed.*1 The ferrite cores
used in our tests are TDK's ZCAT3035.
It should be noted that the ferrite cores should be fitted to the cables in the
position immediately before they are pulled out of the enclosure. If the fitting
position is improper, the ferrite will not produce any effect.
1:To response with CE(EN61131-2/A12), make sure to mount 2 or more
ferrite cores onto the power supply line. The mounting position should be as
near the power supply module as possible.

3.1.6 Noise filter (power supply line filter)
A noise filter is a component which has an effect on conducted noise. With the
exception of some models, it is not required to fit the noise filter to the power
supply line, but fitting it can further suppress noise. (The noise filter has the
effect of reducing conducted noise of 10 M Hz or less.) Use any of the following
noise filters (double type filters) or equivalent.

3.2 Requirements for Compliance with Low Voltage Directives
The Low Voltage Directives apply to the electrical equipment operating from 50
to 1000VAC or 75 to 1500VDC; the manufacturer must ensure the adequate
safety of the equipment.
Guidelines for installation and wiring of MELSEC-A series PLC are provided in
Section 3.2.1 to 3.2.7 for the purpose of compliance with the EMC Directives.
The guidelines are created based on the requirements of the regulations and
relevant standards, however, they do not guarantee that the machinery
constructed according to them will comply with the Directives.
Therefore, the manufacturer of the machinery must finally determine how to
make it comply with the EMC Directives: if it is actually compliant with the EMC
Directives.
3.2.1 Standard applied for MELSEC-A series PLC
The standard applied for MELSEC-A series PLC series is EN61010-1 safety of
devices used in measurement rooms, control rooms, or laboratories.
For the modules which operate with the rated voltage of 50 VAC/75 VDC or
above, we have developed new models that conform to the above standard.
For the modules which operate with the rated voltage under 50 VAC/75 VDC,
the conventional models can be used, because they are out of the low voltage
directive application range.
3.2.2 Precautions when using the MELSEC-A series PLC
Module selection
(1) Power module
For a power module with rated input voltage of 100/200 VAC, select a
model in which the internal part between the first order and second order is
intensively insulated, because it generates hazardous voltage (voltage of
42.4 V or more at the peak) area.
For a power module with 24 VDC rated input, a conventional model can be
used.
(2) I/O module
For I/O module with rated input voltage of 100/200 VAC, select a model in
which the internal area between the first order and second order is
intensively insulated, because it has hazardous voltage area.
For I/O module with 24 VDC rated input, a conventional model can be used.
(3) CPU module, memory cassette, base unit
Conventional models can be used for these modules, because they only
have a 5 VDC circuit inside.
(4) Special function module
Conventional models can be used for the special modules including analog
module, network module, and positioning module, because the rated
voltage is 24 VDC or smaller.
(5) Display device
Use the CE-marked product.
20
3.2.3 Power supply
The insulation specification of the power module was designed assuming installation
category II. Be sure to use the installation category II power supply to the PLC.
The installation category indicates the durability level against surge voltage
generated by a thunderbolt. Category I has the lowest durability; category IV has the
highest durability.
Category IV
Category III
Category II
Category I
Figure 1: Installation Category
Category II indicates a power supply whose voltage has been reduced by two or
more levels of isolating transformers from the public power distribution.
3.2.4 Control panel
Because the PLC is an open device (a device designed to be stored within another
module), be sure to use it after storing in the control panel.
(1) Electrical shock prevention
In order to prevent persons who are not familiar with the electric facility such
as the operators from electric shocks, the control panel must have the
following functions:
(a) The control panel must be equipped with a lock so that only the
personnel who has studied about the electric facility and have enough
knowledge can open it.
(b) The control panel must have a structure which automatically stops the
power supply when the box is opened.
(c) For electric shock protection, use IP20 or greater control panel.
(2) Dustproof and waterproof features
The control panel also has the dustproof and waterproof functions.
Insufficient dustproof and waterproof features lower the insulation withstand
voltage, resulting in insulation destruction. The insulation in our PLC is
designed to cope with the pollution level 2, so use in an environment with
pollution level 2 or below.
Pollution level 1: An environment where the air is dry and conductive dust does not
exist.
Pollution level 2: An environment where conductive dust
does not usually exist, but occasional temporary conductivity
occurs due to the accumulated dust. Generally, this is the level

3.2.5 Module installation
(1) Installing modules contiguously
In Q2AS series PLCs, the left side of each I/O module is left open. When
installing an I/O module to the base, do not make any open slots between
any two modules. If there is an open slot on the left side of a module with
100/200 VAC rating, the printed board which contains the hazardous
voltage circuit becomes bare. When it is unavoidable to make an open slot,
be sure to install the blank module (AG60).
3.2.6 Grounding
There are two kinds of grounding terminals as shown below. Either grounding
terminal must be used grounded.
Be sure to ground the protective grounding for the safety reasons.
Protective grounding
Functional grounding
: Maintains the safety of the PLC and improves
the noise resistance.
: Improves the noise resistance.
3.2.7 External wiring
(1) Module power supply and external power supply
For the remote module which requires 24VDC as module power supply, the
5/12/24/48VDC I/O module, and the special function module which requires
the external power supply, use the 5/12/24/48VDC circuit which is doubly
insulated from the hazardous voltage circuit or use the power supply whose
insulation is reinforced.
(2) External devices
When a device with a hazardous voltage circuit is externally connected to
the PLC, use a model whose circuit section of the interface to the PLC is
intensively insulated from the hazardous voltage circuit.
(3) Intensive insulation
Intensive insulation refers to the insulation with the dielectric withstand
voltage shown in Table 1.

4.2 Fail-Safe Circuit Concept
When the PLC is powered ON and then OFF, improper outputs may be
generated temporarily depending on the delay time and start-up time
differences between the PLC power supply and the external power supply for
the control target (especially, DC).
For example, if the external power supply for the control target is powered ON
and then the PLC is powered ON, the DC output module may generate
incorrect outputs temporarily upon the PLC power-ON. Therefore, it is required
to build the circuit that energizes the PLC by priority.
The external power failure or PLC failure may lead to the system error.
In order to eliminate the possibility of the system error and ensure fail-safe
operation, build the following circuit outside the PLC: emergency circuit,
protection circuit and interlock circuit, as they could cause machine damages
and accidents due to the abovementioned failures.
An example of system design, which is based on fail-safe concept, is provided
on the next page.
28
DANGER z Create a safety circuit outside the PLC to ensure the whole
system will operate safely even if an external power failure
or a PLC failure occurs.
Otherwise, incorrect output or malfunction may cause an
accident.
(1) For an emergency stop circuit, protection circuit and
interlock circuit that is designed for incompatible actions
such as forward/reverse rotation or for damage
prevention such as the upper/lower limit setting in
positioning, any of them must be created outside the
PLC.
(2) When the PLC detects the following error conditions, it
stops the operation and turn off all the outputs.
x The overcurrent protection device or overvoltage
protection device of the power supply module is
activated.
x The PLC CPU detects an error such as a watchdog
timer error by the self-diagnostics function.
In the case of an error of a part such as an I/O control
part that cannot be detected by the PLC CPU, all the
outputs may turn on. In order to make all machines
operate safely in such a case, set up a fail-safe circuit
or a specific mechanism outside the PLC.
(3) Depending on the failure of the output module’s relay or
transistor, the output status may remain ON or OFF
incorrectly. For output signals that may lead to a serious
accident, create an external monitoring circuit.
z Design a circuit so that the external power will be supplied
after power-up of the PLC.
Activating the external power supply prior to the PLC may
result in an accident due to incorrect output or malfunction.
z If load current more than the rating or overcurrent due to a
short circuit in the load has flowed in the output module for a
long time, it may cause a fire and smoke. Provide an
external safety device such as a fuse.
z For the operation status of each station at a communication
error in data link, refer to the respective data link manual.
The communication error may result in an accident due to
incorrect output or malfunction.
29
DANGER z When controlling a running PLC (data modification) by
connecting a peripheral device to the CPU module or a PC
to a special function module, create an interlock circuit on
sequence programs so that the whole system functions
safely all the time.
Also, before performing any other controls (e.g. program
modification, operating status change (status control)), read
the manual carefully and ensure the safety.
In these controls, especially the one from an external device
to a PLC in a remote location, some PLC side problem may
not be resolved immediately due to failure of data
communications.
To prevent this, create an interlock circuit on sequence
programs and establish corrective procedures for
communication failure between the external device and the
PLC CPU.
z When setting up the system, do not allow any empty slot on
the base unit.
If any slot is left empty, be sure to use a blank cover (AG60)
or a dummy module (AG62) for it.
When using the extension base unit, A52B, A55B or A58B,
attach the included dustproof cover to the module in slot 0.
Otherwise, internal parts of the module may be flied in the
short circuit test or when an overcurrent or overvoltage is
accidentally applied to external I/O section.
CAUTION z Do not install the control lines or communication cables
together with the main circuit or power lines, or bring them
close to each other.
Keep a distance of 100mm (3.9inch) or more between them.
Failure to do so may cause malfunctions due to noise.
z When an output module is used to control the lamp load,
heater, solenoid valve, etc., a large current (ten times larger
than the normal one) may flow at the time that the output
status changes from OFF to ON. Take some preventive
measures such as replacing the module with the one of a
suitable current rating.

[1] Switch the power supply ON.
[2] Set the CPU module to RUN.
[3] Switch RA2 ON when the DC power supply starts.
[4] Switch the timer (TM) ON when the DC power

(The set value for TM must be the time it takes for
100% establishment of the DC power after RA2 is
switched ON. Make this set value 0.5 seconds.)
[5] Switch the start switch ON.
[6] The output devices are driven in accord-ance with
the program when the magnetic contactor (MC)
comes ON.
(If a voltage relay is used at RA2, no timer (TM) is
necessary in the program.)
31
(2) Fail-safe measures to cover the possibility of PLC failure
Problems with a CPU module and memory can be detected by the self
diagnostics function. However, problems with I/O control area may not be
detected by the CPU module.
In such cases, all I/O points turn ON or OFF depending on the problem,
and normal operation and safety cannot be maintained.
Though Mitsubishi PLCs are manufactured under strict quality control, they
may fail or malfunction due to unspecified reasons. To prevent the whole
system failure, machine breakdown, and accidents, build a fail-safe circuit
outside the PLC.
Examples of a system and its fail-safe circuitry are described below:

POINTS
*1: Overcurrent protection
The overcurrent protection device shuts off the 5VDC and/or 24VDC
circuit(s) and stops the system if the current exceeding the specified
value flows in the circuit(s).
As this results in voltage drop, the power supply module LED turns
OFF or is dimly lit.
After that, eliminate the causes of overcurrent, e.g., insufficient
current capacity and short circuit, and then start the system.
When the current has reached the normal value, the initial start up of
the system will be performed.
*2: Overvoltage protection
The overvoltage protection shuts off the 5VDC circuit and stops the
system if the overvoltage of 5.5 to 6.5V is applied to the circuit.
This results in the power supply module LED turning OFF.
When restarting the system, power OFF and ON the input power
supply, and the initial start up of the system will be performed.
If the system is not booted and the LED remains off, this means that
the power supply module has to be replaced.
*3: Allowable momentary power failure period
The PLC CPU allowable momentary power failure period varies with
the power supply module used.
In case of the A1S63P power supply module, the allowable
momentary power failure period is defined as the time from when the
primary side of the stabilized power supply for supplying 24VDC to
the A1S63P is turned OFF until when the voltage (secondary side)
has dropped from 24VDC to the specified value (15.6VDC) or less.
*4: Inrush current
If the power supply module is re-powered ON right after powered
OFF (within 5seconds), the inrush current exceeding the specified
value (2ms or less) may be generated. Therefore, make sure to
re-power ON the module 5seconds after power off.
When selecting a fuse or breaker for external circuit, consider the
above point as well as meltdown and detection characteristics.

(g) 100VAC, 200VAC, and 24VDC wires should be twisted as tightly as
possible, and connect the modules at the shortest distance between
them.
To minimize voltage drop, use thick wires (MAX. 2mm2) where
possible.
(h) Do not bind 100VAC and 24VDC wires together with main circuit (high
tension and large current) wires or I/O signal lines (including common
line) nor place them near each other. Provide 100mm (3.94 inch)
clearance between the wires if possible.

POINT
(1) Provide separate grounding for the lightning surge absorber (E1) and the
PLC (E2).
(2) Select a lightning surge absorber whose maximum allowable circuit
voltage is higher than the circuit voltage at the maximum power supply
voltage.
(2) Wiring to I/O device
(a) The solderless terminal with insulation sleeve is inapplicable to a
terminal block.
It is advisable to cover the wire connection part of a terminal with a
mark tube or insulation tube.
45
(b) Install wiring to a terminal block using the cable of core diameter 0.3 to
0.75mm2, and outside diameter 2.8mm or less.
(c) Run the I/O line and output line away from each other.
(d) When the main circuit line and power line cannot be separated, use a
shielding cable and ground it on the PLC side.
However, ground it on the opposite side in some cases.

(e) When cables are run through pipes, securely ground the pipes.
(f)
Run the 24VDC input line away from the 100VAC and 200 VAC lines.
(g) The cabling of 200m (656.2ft.) or longer distance may produce
leakage current depending on the capacity between lines and result in
an accident.
(h) As a countermeasure against the power surge due to lightning,
separate the AC wiring and DC wiring and connect a surge absorber
for lightning as shown in (i) of item (1).
Failure to do so increases the risk of I/O device failure due to lightning.
(3) Grounding
CAUTION z Be sure to ground the FG terminals and LG terminals to
the protective ground conductor. Not doing so could
result in electric shock or erroneous operation.
(a) Carry out the independent grounding if possible. (Grounding

(1) Use the thickest possible (max. 2 mm2 (14 AWG)) wires for the 100/200
VAC and 24 VDC power cables. Be sure to twist these wires starting at
the connection terminals. For wiring a terminal block, be sure to use a
solderless terminal. To prevent short-circuit due to loosening screws,
use the solderless terminals with insulation sleeves of 0.8 mm (0.03
inch) or less thick. The number of the solderless terminals to be
connected for one terminal block are limited to 2.
Solderless terminals

(2) When the LG and FG terminals are connected, they must be grounded.
If they are not grounded, the operations will be easily influenced by
noise. Be aware not to touch the LG terminal since it has potential of half
the input voltage.
4.4 Precaution when Connecting the Uninterruptive Power Supply (UPS)
Be sure of the following terms when connecting the PLC system to the
uninterruptive power supply (abbreviated as UPS hereafter):
As for UPS, use the online power system or online interactive system with a
voltage distortion rate of 5% or less.
For the UPS of the commercial online power system, use Mitsubishi Electric's F
Series UPS (serial number P or later) (Ex.: FW-F10-0.3K/0.5K).
Do not use any UPS of the commercial online power system other than the F
series mentioned above.

The following specifications apply to all modules:
Isolation method
: Photocoupler
Input indication
: LEDs
*1 : The ON/OFF status of the first or latter half is indicated by the LEDs in
accordance with the setting of the selector switch on the front panel of the
module:
FH setting: First half (Y00 to Y1F), LH setting: Latter half (Y20 to Y3F)
*2 : When 12/48 VDC is used as the load power supply, a separate 24 VDC power
supply must be used as an external power supply.
*3 : When 12 VDC is used as the load power supply, a separate 24/48 VDC power
supply must be used as an external power supply.
*4 : When the module is installed adjacent to the power supply module, the value
indicated in parentheses applies.
*5 : The maximum load current differs depending on the number of simultaneously
ON points.
*6 : Fast-melting fuse (one per common)
*7 : Normal fuse (two per common)
*8 : Fast-melting fuse (two per 8-per-common unit)
*9 : Fast-melting fuse (two per common)
*10 : LED comes on when a fuse blows or the external power supply is turned off.
*11 : Since this is a built-in fuse directly fixed to the module, replace the entire
module if it blows.
*12 : TYP. 12 VDC

*1 : The same numbers are allocated to both input and output points. The number
of occupied I/O points is 64.
*2 : The first half 32 points are allocated to input and the latter half 32 points are
allocated to output. Thus, the number of occupied I/O points is 64. When I/O
allocation is carried out at a peripheral device, both modules should be set as
64-point output modules.

6.4 Canceling of Errors
Q series CPU module can perform the cancel operation for errors only when the
errors allow the CPU module to continue its operation.
To cancel the errors, follow the steps shown below.
1) Eliminate the cause of the error.
2) Store the error code to be canceled in the special register SD50.
3) Energize the special relay SM50 (OFF
ON).
4) The error to be canceled is canceled.
After the CPU module is reset by the canceling of the error, the special relays,
special registers, and LEDs associated with the error are returned to the status
under which the error occurred.
If the same error occurs again after the cancellation of the error, it will be registered
again in the error history.
When multiple enunciators(F) detected are canceled, the first one with No. F only is
canceled.
Refer to the following manual for details of error canceling.
QCPU User's Manual (Function Explanation, Program Fundamentals
POINT
(1) When the error is canceled with the error code to be canceled stored in
the SD50, the lower one digit of the code is neglected.
(Example)
If error codes 2100 and 2101 occur, and error code 2100 to cancel error
code 2101.
If error codes 2100 and 2111 occur, error code 2111 is not canceled
even if error code 2100 is canceled.
(2) Errors developed due to trouble in other than the CPU module are not
canceled even if the special relay (SM50) and special register (SD50)
are used to cancel the error.
(Example)
Since "SP. UNIT DOWN" is the error that occurred in the base unit
(including the extension cable), intelligent function module, etc. the error
cause cannot be removed even if the error is canceled by the special
relay (SM50) and special register (SD50).
Refer to the error code list and remove the error cause.
