z SAFETY PRECAUTIONS z
(Read these precautions before using.)
When using Mitsubishi equipment, thoroughly read this manual and the
associated manuals introduced in this manual.
Also pay careful attention to safety and handle the module properly.
These z SAFETY PRECAUTIONS z classify the safety precautions into two
categories: "DANGER" and "CAUTION".
DANGER
CAUTION
Procedures which may lead to a dangerous condition
and cause death or serious injury if not carried out
properly.
Procedures which may lead to a dangerous condition
and cause superficial to medium injury, or physical
damage only, if not carried out properly.
CAUTION may
Depending on circumstances, procedures indicated by
also be linked to serious results.
In any case, it is important to follow the directions for usage.
Store this manual in a safe place so that you can take it out and read it
whenever necessary. Always forward it to the end user.
[DESIGN PRECAUTIONS]
DANGER
Install a safety circuit external to the PLC that keeps the entire system
safe even when there are problems with the external power supply or the
PLC module. Otherwise, trouble could result from erroneous output or
erroneous operation.
(1) Outside the PLC, construct mechanical damage preventing interlock
circuits such as emergency stop, protective circuits, positioning upper
and lower limits switches and interlocking forward/reverse operations.
A-1
[DESIGN PRECAUTIONS]
DANGER
(2) When the PLC detects the following problems, it will stop calculation
and turn off all output in the case of (a). In the case of (b), it will stop
calculation and hold or turn off all output according to the parameter
setting.
Note that the AnS series module will turn off the output in either of
cases (a) and (b).
(a) The power supply module has over current
protection equipment and over voltage protection equipment.
(b) The PLC CPUs self-diagnosis functions, such as the watch dog
timer error, detect problems.
In addition, all output will be turned on when there are problems that
the PLC CPU cannot detect, such as in the I/O controller. Build a fail
safe circuit exterior to the PLC that will make sure the equipment
operates safely at such times. See section 9.1 of this manual for
example fail safe circuits.
(3) Output could be left on or off when there is trouble in the outputs
module relay or transistor. So build an external monitoring circuit that
will monitor any single outputs that could cause serious trouble.
When overcurrent which exceeds the rating or caused by short-circuited
load flows in the output module for a long time, it may cause smoke or
fire. To prevent this, configure an external safety circuit, such as fuse.
Build a circuit that turns on the external power supply when the PLC main
module power is turned on. If the external power supply is turned on
first, it could result in erroneous output or erroneous operation.
When a data link results in a communication error, the faulty station
changes in operating status depending on the used data link type.
(1) For the data link data, the data prior to the communication error will be
held.
(2) The MELSECNET (II,/B,/10) remote I/O station will turn all output off.
(3) The MELSECNET/MINI-S3 remote I/O station will hold the output or
turn all output off depending on the E.C. remote setting.
Refer to the data link manuals regarding the method for setting the
communication problem station and the operation status when there are
communication problem.
A-2
[DESIGN PRECAUTIONS]
DANGER
When connecting a peripheral device to the CPU module or connecting a
personal computer or the like to the intelligent function module to
exercise control (data change) on the running PLC, configure up an
interlock circuit in the sequence program to ensure that the whole
system will always operate safely.
Also before exercising other control (program change, operating status
change (status control)) on the running PLC, read the manual carefully
and fully confirm safety.
Especially for the above control on the remote PLC from an external
device, an immediate action may not be taken for PLC trouble due to a
data communication fault.
In addition to configuring up the interlock circuit in the sequence program,
corrective and other actions to be taken as a system for the occurrence of
a data communication fault should be predetermined between the external
device and PLC CPU.
When configuring a system, do not leave any slots vacant on the base.
Should there be any vacant slots, always use a blank cover (A1SG60) or
dummy module (A1SG62).
When the extension base A1S52B, A1S55B or A1S58B is used, attach the
dustproof cover supplied with the product to the module installed in slot
0.
If the cover is not attached, the module's internal parts may be
dispersed when a short-circuit test is performed or
overcurrent/overvoltage is accidentally applied to the external I/O area.
CAUTION
Do not bunch the control wires or communication cables with the main
circuit or power wires, or install them close to each other. They should
be installed 100 mm (3.94 inch) or more from each other. Not doing so
could result in noise that would cause erroneous operation.
When controlling items like lamp load, heater or solenoid valve using an
output module, large current (approximately ten times greater than that
present in normal circumstances) may flow when the output is turned
OFF to ON.
Take measures such as replacing the module with one having sufficient
rated current.
A-3
[INSTALLATION PRECAUTIONS]
CAUTION
Use the PLC in an environment that meets the general specifications
contained in this manual. Using this PLC in an environment outside the
range of the general specifications could result in electric shock, fire,
erroneous operation, and damage to or deterioration of the product.
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.
When installing extension cables, be sure that the connectors of base
unit are installed correctly. After installation, check them for looseness.
Poor connections could cause an input or output failure.
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.
Completely turn off the external power supply before loading or
unloading the module. Not doing so could result in electric shock or
damage to the product.
Do not directly touch the module's conductive parts or electronic
components. Touching the conductive parts could cause an operation
failure or give damage to the module.
A-4
[WIRING PRECAUTIONS]
DANGER
Completely turn off the external power supply when installing or placing
wiring. Not completely turning off all power could result in electric shock
or damage to the product.
When turning on the power supply or operating the module after
installation or wiring work, be sure that the module's terminal covers are
correctly attached. Not attaching the terminal cover could result in
electric shock.
CAUTION
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.
When wiring in the PLC, be sure that it is done correctly by checking the
product's rated voltage and the terminal layout. Connecting a power
supply that is different from the rating or incorrectly wiring the product
could result in fire or damage.
Do not connect multiple power supply modules in parallel. Doing so
could cause overheating, fire or damage to the power supply module.
External connections shall be crimped or pressure welded with the
specified tools, or correctly soldered. Imperfect connections could result
in short circuit, fires, or erroneous operation.
Tighten the terminal screws with the specified torque. If the terminal
screws are loose, it could result in short circuits, fire, or erroneous
operation. Tightening the terminal screws too far may cause damages to
the screws and/or the module, resulting in fallout, short circuits, or
malfunction.
Be sure there are no foreign substances such as sawdust or wiring
debris inside the module. Such debris could cause fires, damage, or
erroneous operation.
The module has an ingress prevention label on its top to prevent foreign
matter, such as wire offcuts, from entering the module during wiring.
Do not peel this label during wiring.
Before starting system operation, be sure to peel this label because of
heat dissipation.
A-5
[STARTUP AND MAINTENANCE PRECAUTIONS]
DANGER
Do not touch the terminals while power is on.
Doing so could cause shock or erroneous operation.
Correctly connect the battery.
Also, do not charge, disassemble, heat, place in fire, short circuit, or
solder the battery. Mishandling of battery can cause overheating or
cracks which could result in injury and fires.
Switch all phases of the external power supply off when cleaning the
module or retightening the terminal or module mounting screws. Not
doing so could result in electric shock.
Undertightening of terminal screws can cause a short circuit or
malfunction. Overtightening of screws can cause damages to the screws
and/or the module, resulting in fallout, short circuits, or malfunction.
A-6
[STARTUP AND MAINTENANCE PRECAUTIONS]
CAUTION
The online operations conducted for the CPU module being operated,
connecting the peripheral device (especially, when changing data or
operation status), shall be conducted after the manual has been carefully
read and a sufficient check of safety has been conducted.
Operation mistakes could cause damage or problems with of the
module.
Do not disassemble or modify the modules.
Doing so could cause trouble, erroneous operation, injury, or fire.
Use any radio communication device such as a cellular phone or a PHS
phone more than 25cm (9.85 inch) away from the PLC.
Not doing so can cause a malfunction.
Switch all phases of the external power supply off before mounting or
removing the module. If you do not switch off the external power supply,
it will cause failure or malfunction of the module.
Do not drop or give an impact to the battery installed in the module.
Otherwise the battery will be broken, possibly causing internal leakage
of electrolyte. Do not use but dispose of the battery if it has fallen or an
impact is given to it.

3. EMC DIRECTIVE AND LOW-VOLTAGE INSTRUCTION
3.1 Requirements for Compliance to EMC Directive (89/336/EEC)
The EMC Directive (89/336/EEC) will become mandatory within Europe from
January 1st 1996. The EMC directive in essence defines the amount of
electromagnetic output a product is allowed to produce and how susceptible that
product is to electromagnetic interference. Any manufacturer or importer of
electrical/electronic apparatus must before releasing or selling products within
Europe after that date have either a CE mark attached to their goods. Testing to
comply with the directive is done by use of agreed European standards which
define limits for radiated and mains conducted electromagnetic emissions from
equipment, levels of immunity to radiated emissions, ability for equipment to cope
with transient voltage surges and electro-static discharges.
When installed in the specified manner this unit will be compliant with the relevant
standards EN50081-2 and prEN50082-2 as applicable in the EMC directive. Failure
to comply with these instructions could lead to impaired EMC performance of the
equipment and as such Mitsubishi Electric Corporation can accept no liability for
such actions.
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.

(*1) QP: Quasi-peak value, Mean : Average value
(*2) The PLC is an open type device (device installed to another device) and must
be installed in a conductive control box.
The tests for the corresponding items were performed while the PLC was
installed to inside the control box.
3.1.2 Installation inside the control cabinet
Since the PLC is an open type device (device incorporated into another device), it
must be installed in the control cabinet. This has a good effect of not only for
assuring safety but also for shielding noise emitted from the PLC, by means of the
control cabinet.
(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.
10
(d) Earth the control cabinet with a thick wire so that a low impedance
connection to ground can be ensured even at high frequencies.
(22mm2 wire or thicker is recommended.)
(e) Holes made in the control cabinet must be 10cm (3.94in.) diameter or
less. If the holes are 10cm (3.94in.) or larger, radio frequency noise
may be emitted.
(2) Connection of power and ground 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 30cm (11.18in.) or shorter.) The LG and FG terminals
function is to pass the noise generated in the PC system to the
ground, so an impedance that is as low as possible must be ensured.
As the wires are used to relieve the noise, the wire itself carries a
large noise content and thus short wiring means that the wire is
prevented from acting as an antenna.
Note)
A long conductor will become a more efficient antenna at high frequency.
(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 led from the control cabinet contain a high frequency noise element and
outside the control panel these cables act as antennae and radiate noise. The
cables connected to input/output modules or special modules which leave the
control panel must always be shielded cables.
Mounting of a ferrite core on the cables is not required (excluding some models) but
if a ferrite core is mounted, the noise radiated through the cable can be suppressed
further.
Use of a shielded cable is also effective for increasing the noise immunity level. The
PLC system's input/output and special function module provide a noise immunity
level of equivalent to that stated in IEC801-4 : 2 k V when a shielded cable is used.
If a shielded cable is not used or if the shield earthing treatment is not suitable even
when used (See Section 9.1.2.4), the noise immunity level is less than 2 kV.
Note)
prEN50082-2 specifies the noise resistance level based on the signal wire
application.
Signals involved in process control :
2kV
Signals not involved in process control : 1kV
The meaning of "involved in process control" is not defined in prEN50082-2.
However, when the purposes of the EMC Directive are considered, the signals that
could cause personal injury or risks in the facility if a malfunction occurs should be
defined as "signals involved in process control". Thus, it is assumed that a high
noise immunity level is required.
12
(1) Shield earthing
When a shield of the shielded cable is earthed to the cabinet body, please ensure
that the shield contact with the body is over a large surface area. If the cabinet body
is painted it will be necessary to remove paint from the contact area. All fastenings
must be metallic and the shield and earthing contact must be made over the largest
available surface area. If the contact surfaces are too uneven for optimal contact to
be made either use washers to correct for surface inconsistencies or use an
abrasive to level the surfaces. The following diagrams show examples of how to
provide good surface contact of shield earthing by use of a cable clamp.
Screw
Clamp fitting

Paint mask
(a) Peal the cable insulation off and

(b) Sandwich the exposed shield section with the and
earth to the control cabinet over a wide area.
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 module
(a) The following requirements apply to AJ71AR21, AJ71BR11,
AnNCPUR21, AnACPUR21.
Always use a triaxial cable for the module. The radiated noise in the
band of 30 M Hz or higher can be suppressed by using a triax cable.
Earth the outer shield by the method described in (1).

(b) Always mount a ferrite core onto the triaxial cable. Mount the ferrite
core near the control cabinet outlet of each cable. Use of the TDK
ZCAT3035 ferrite core is recommended.

(3) Ethernet module
(a) Always earth the AUI cable connected to the A1SJ71E71-B5. The AUI
is a shielded cable so remove the outer insulation and connect to
earth the exposed shield section using as wide a surface area as
possible in the manner shown below.

3.1.5 Ferrite core
A ferrite core is effective for reducing noise in the band of 30 M Hz to 100 M Hz.
Mounting of a ferrite core is not necessary except for some particular models
described in Section 9.1.3 (2), (3). However if further attenution of noise is
necessary, mounting of a ferrite core on cables which radiate noise is
recommended. When a ferrite core is mounted, mount the ferrite core just before
the point where the cable goes outside of the cabinet. The ferrite will not be effective
if the mounting position is not adequate.

ferrite.
3.1.6 Noise filter (power supply line filter)
The noise filter (power supply line filter) is a device effective to reduce conducted
noise. Except some particular models described in Section 9.1.3 (5), installation of a
noise filter onto the power supply lines is not necessary. However conducted noise
can be reduced if it is installed. (The noise filter is generally effective for reducing
conducted noise in the band of 10 M Hz or less.) Usage of the following filters is
recommended.

3.2 Requirement to Conform to the Low-Voltage Instruction
The low-voltage instruction, one of the European Instructions, is now regulated.
The low-voltage instruction require each device which operates with power supply
ranging from 50 V AC to 1000 V and 75 V DC to 1500 V to satisfy necessary safety
items.
In the Sections from 3.2.1 to 3.2.7, cautions on installation and wiring of the
MELSEC-A series PC to conform to The Low Voltage Directive requires are
described.
We have put the maximum effort to develop this material based on the
requirements and standards of the regulation that we have collected. However,
compatibility of the devices which are fabricated according to the contents of this
manual to the above regulation is not guaranteed. Each manufacturer who
fabricates such device should make the final judgement about the application
method of the low-voltage instruction and the product compatibility.
3.2.1 Standard applied for MELSEC-A
The standard applied for MELSEC-A is EN61010-1 safety of devices used in
measurement rooms, control rooms, or laboratories.
For the modules which operate with the rated voltage of 50VAC/75VDC or above,
we have developed new models that conform to the above standard.
For the modules which operate with the rated voltage under 50VAC/75VDC, the
conventional models can be used, because they are out of the Low Voltage
Directive application range.
3.2.2 Precautions when using the A series
Module selection
(1) Power module
For a power module with rated input voltage of 100/200VAC, 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 42.4V or more at the peak) area.
For a power module with 24VDC rated input, a conventional model can be
used.
(2) I/O module
For I/O module with rated input voltage of 100/200VAC, 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 24VDC rated input, a conventional model can be
used.
18
(3) CPU module, memory cassette, base unit
Conventional models can be used for these modules, because they only
have a 5VDC circuit inside.
(4) Special module
Conventional models can be used for the special modules including
analog module, network module, and positioning module, because the
rated voltage is 24VDC or less.
(5) Display device
Use an A900 series GOT CE compatible model.
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
PC.
The installation category indicates the durability level against surge voltage
generated by lighening strike. 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.
19
3.2.4 Control box
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 box.
(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 box must have the
following functions :
(a) The control box 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 box must have a structure which automatically stops the
power supply when the box is opened.
(2) Dustproof and waterproof features
The control box 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 pollustion 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 for inside the control box equivalent to
IP54 in a control room or on the floor of a typical
factory.
Pollution level 3 : An environment where conductive dust exits and
conductivity may be generated due to the
accumulated dust.
An environment for a typical factory floor.
Pollution level 4 : Continuous conductivity may occur due to rain,
snow, etc. An outdoor environment.
As shown above, the PC can realize the pollution level 2 when stored in a
control cabinet equivalent to IP54.
20
3.2.5 Module installation
(1) Installing modules contiguously
In A series PCs, 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 100/200VAC rating, the printed board which contains the hazardous
voltage circuit becomes bare. When it is unavoidable to leave an open slot,
be sure to install the blank module (AG60).
When using the A5…B expansion base with no power supply, attach the
cover packaged with the expansion base to the side of the leftmost
module.
3.2.6 Grounding
There are two kinds of grounding terminals as shown below.
terminal must be used grounded.
Either grounding
Be sure to ground the protective grounding for the safety reasons.

Functional grounding
: Improves the noise resistance.
3.2.7 External wiring
(1) 24VDC external power supply
For special modules that require a 24 V DC I/O module or external power
supply, use a model whose 24 V DC circuit is intensively insulated from
the hazardous voltage circuit.
(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) Insulation requirements

4. LOADING AND INSTALLATION
4.1 Installing Modules
4.1.1 Precautions for handling of modules
This section describes the precautions that must be taken when handling the CPU,
I/O modules, special function modules, power supply module, base units, etc.
(1) Module enclosure, memory cassette, terminal block connectors and pin
connectors are made of resin; do not drop them or subject them to strong
impact.
(2) Do not remove modules' printed circuit boards from the plastic casing.
(3) During wiring, take care to ensure that wiring off cuts, etc. do not get
inside the case.
If anything does get inside the case, remove it.
(4) Tighten the module mounting (unnecessary in normal operating condition)
and terminal block screws as indicated below.

(5) To install a module, push it firmly into the base unit so that the latch
engages properly. To remove a module, press the latch to disengage it
from the base unit, then pull the module out (for details, refer to the
relevant PC CPU User's Manual.
4.1.2 Installation environment
The CPU system should not be installed under the following environmental
conditions:
(1) Places where ambient temperature is outside of 0 to 55°C range.
(2) Places where ambient humidity is outside of 10 to 90%RH range.
(3) Places where dewing (condensation) occurs due to sudden temperature
changes.
22
(4) Places where corrosive or inflammable gas exists.
(5) Places where a large amount of dust, iron powder and other conductive
powder, oil mist, salt or organic solvent exists.
(6) Places exposed to direct sunlight.
(7) Places where a strong electric or magnetic field exists.
(8) Places where mechanical vibrations or impacts are transmitted directly to
the module body.
4.1.3 Precautions relating to the installation of the base unit
The following precautions must be observed when installing a PC to an operation
panel or other bases considering fully the operability, maintainability, and resistance
to the environment.
(1) Unit mounting position
To ensure proper ventilation and make module replacement easy, provide
a clearance of 80mm (3.15in.) or more between the top of the unit and any
surrounding structure or equipment.
Represents the ceiling of panel,
wiring conduit, or component.

23
(2) A wiring conduit should be provided if required.
If its clearance above or below the programmable controller is less than
indicated in the figure above, observe the following points:
(a) If the wiring conduit is installed above the programmable controller, its
height must be no greater than 50 mm (1.97in.) to ensure good
ventilation.
In addition, there should be adequate space between the
programmable controller and the wiring conduit to allow module latches
to be pressed.
It will not be possible to replace modules if their latches cannot be
pressed.
(b) If the wiring conduit is installed below the programmable controller, it
should be installed so as to allow connection of the optical fiber cable
or coaxial cable, taking the minimum bending radius of the cable into
consideration.

When using φ4.5mm optical fiber cable,
or coaxial cable ............................................100mm (3.94in.) or more
When using φ8.5mm optical fiber cable ..........130mm (5.12in.) or more
24
(3) Unit mounting orientation
(a) Since the PC generates heat, mount it in a well-ventilated location
and in the orientation shown below.
(b) Do not mount it in either of the orientations shown below.
Vertical
Flat
(4) Mount base units on a flat surface.
If the mounting surface is uneven, this may strain the printed circuit boards
and cause malfunctions.
(5) Avoid mounting the base unit in proximity to vibration sources such as
large magnetic contactors and no-fuse circuit breakers; mount these on a
separate panel or at a distance.
(6) In order to avoid the effects of radiated noise and heat, provide the
clearances indicated below between the PC and devices that generate
noise or heat (contactors and relays).
• Required clearance in front of........................100mm or more (3.94inch)
• Required clearance on the right and left of ......50mm or more (1.97inch)

4.2 The view of a Fail-safe Circuit
When the programmable controller is switched ON/OFF, the outputs may
temporarily be incorrect due to the delay time and difference between the start-up
time of the programmable controller's power supply and that of the external power
supply for process control (especially if it is DC).
For example, if the power to the PC is turned ON after turning ON the external
power supply used for the process control with the DC output module, the DC
output module may make an erroneous output for an instant.
There is a possibility of abnormal operation if the external power supply is abnormal
or a programmable controller fault occurs.
To prevent the abnormal operation of the whole system, machine breakdown, and
accidents, build a fail-safe circuit (emergency stop, protective circuit, interlocking
circuit, etc.) outside the PC.
26
The next page shows an example of the system design circuits, based on the
considerations described above.
DANGER z Install a safety circuit external to the PC that keeps the entire
system safe even when there are problems with the external
power supply or the PC module. Otherwise, trouble could
result from erroneous output or erroneous operation.
(1) Outside the PC, construct mechanical damage
preventing interlock circuits such as emergency stop,
protective circuits, positioning upper and lower limits
switches and interlocking forward /reverse operations.
(2) When the PC detects the following problems, it will stop
calculation and turn off all output.
x The power supply module has over current protection
equipment and over voltage protection equipment.
x The PC CPUs self-diagnostic functions, such as the
watchdog timer error, detect problems. In addition, all
output will be turned on when there are problems that
the PC CPU cannot detect, such as in the I/O
controller. Build a fail safe circuit exterior to the PC that
will make sure the equipment operates safely at such
times. See Section 4.2 of this user's manual for
example fail safe circuits.
See this user's manual for example fail safe circuits.
(3) Output could be left on or off when there is trouble in the
outputs module relay or transistor. So build an external
monitoring circuit that will monitor any single outputs that
could cause serious trouble.
z Build a circuit that turns on the external power supply
when the PC main module power is turned on. If the
external power supply is turned on first, it could result in
erroneous output or erroneous operation.

[1] Switch the power supply ON.
[2] Set the CPU module to RUN.
[3] Switch the start switch ON.
[4] The output devices are driven in accordance
with the program when the magnetic
contactor (MC) comes ON.
AC/DC system
[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
supply reaches working voltage.
(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.)
28
(2) Fail-safe measures to cover the possibility of PC failure
Problems with a CPU or memory can be detected by the self diagnosis function.
However, problems with I/O control area may not be detected by the CPU.
In such cases, all I/O points turn ON or OFF depending on a condition of
problem, and normal operating conditions and operating safety cannot
sometimes be maintained.
Though Mitsubishi PCs are manufactured under strict quality control, they may
cause failure or abnormal operations due to unspecified reasons. To prevent
abnormal operations of whole system, machine breakdown, and accidents, build
a fail-safe circuit outside the PC.
The following gives an example of a fail-safe circuit.

POINTS
*1 : Overcurrent protection
(a) The overcurrent protection device shuts off the 5VDC, 24VDC
ladder and stops the system if the current flowing in the ladder
exceeds the specified value.
When this device is activated, the power supply module LED is
switched off or dimly lit.
(b) If this happens, eliminate the cause of the overcurrent  for
example insufficient current capacity or short ladder  then
start up the system.
When the current has returned to normal, the system
undergoes an initial start.
*2 : Overvoltage protection
The overboltage protection device shuts off the 5 VDC ladder and
stops the system if an excessive voltage in the range 5.5 to 6.5V is
applied to this ladder.
When this device is activated, the power supply module LED is
switched off. If this happens, switch the input power OFF, then
back ON to restart the system.
If the system is not booted and the LED remains off, the power
supply module must be changed.
*3 : Allowable momentary power interruption time
The PC CPU allowable momentary power interruption time varies
according to the type of power supply module.
In the case of the A63P module, the allowable momentary power
interruption time is defined as from when the 24VDC stabilized
primary supply is cut off until the 24VDC voltage drops to the
defined voltage (15.6VDC).

(2) Do not supply 24VDC power from more than one power supply modules in
parallel to one I/O module. If they are connected in parallel, the power
supply modules may fail.
If the 24VDC output capacity is insufficient for one power supply module,
supply 24VDC from the external 24VDC power supply as shown below:
24 VDC
External power supply
(3) 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.
39
(4) Do not bind 100VAC and 24VDC wires together with main circuit (high
tension and large current) wires or I/O signal wires nor place them near
each other. Provide 100mm (3.94 inch) clearance between the wires if
possible.
(5) As a measure against surges caused by lightning, insert a lightning surge
absorber as shown below.

POINTS
(1) Use thick wires (MAX. 2mm2) possible for the 100/200VAC and 24VDC
power supply, and twist the wires from connected terminals. When a
solderless terminal is used, use a solderless terminal with an insulation
sleeve to prevent short-circuit if the terminal screw becomes loose.
(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 items when connecting the ACPU system to the
uninterruptive power supply (abbreviated as UPS hereafter) :
Use a UPS which employs the constant inverter power supply method with 5% or
less voltage fluctuation.
Do not use a UPS with the constant commercial power supply method.

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 (X00 to X1F), LH setting: Latter half (X20 to X3F)
*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
