[Design Precautions]
WARNING
● Configure safety circuits external to the programmable controller to ensure that the entire system
operates safely even when a fault occurs in the external power supply or the programmable controller.
Failure to do so may result in an accident due to an incorrect output or malfunction.
(1) Emergency stop circuits, protection circuits, and protective interlock circuits for conflicting
operations (such as forward/reverse rotations or upper/lower limit positioning) must be configured
external to the programmable controller.
(2) When the programmable controller detects an abnormal condition, it stops the operation and all
outputs are:
• Turned off if the overcurrent or overvoltage protection of the power supply module is activated.
• Held or turned off according to the parameter setting if the self-diagnostic function of the head
module detects an error such as a watchdog timer error.
Also, all outputs may be turned on if an error occurs in a part, such as an I/O control part, where
the head module cannot detect any error. To ensure safety operation in such a case, provide a
safety mechanism or a fail-safe circuit external to the programmable controller. For a fail-safe
circuit example, refer to Page 147, Appendix 10.
(3) Outputs may remain on or off due to a failure of a component such as a relay and transistor in an
output circuit. Configure an external circuit for monitoring output signals that could cause a
serious accident.
● In an output circuit, when a load current exceeding the rated current or an overcurrent caused by a
load short-circuit flows for a long time, it may cause smoke and fire. To prevent this, configure an
external safety circuit, such as a fuse.
● Configure a circuit so that the programmable controller is turned on first and then the external power
supply. If the external power supply is turned on first, an accident may occur due to an incorrect output
or malfunction.
● Configure a circuit so that the external power supply is turned off first and then the programmable
controller. If the programmable controller is turned off first, an accident may occur due to an incorrect
output or malfunction.
● For the operating status of each station after a communication failure, refer to relevant manuals for
each network. Incorrect output or malfunction due to a communication failure may result in an
accident.
● When changing data from a peripheral device connected to the head module during operation,
configure an interlock circuit in the program of the master station to ensure that the entire system will
always operate safely.
For other controls to a running programmable controller (such as modification of the master station
program or operating status change), read relevant manuals carefully and ensure the safety before
the operation. Especially, when a remote programmable controller is controlled by an external device,
immediate action cannot be taken if a problem occurs in the programmable controller due to a
communication failure. To prevent this, configure an interlock circuit in the program of the master
station, and determine corrective actions to be taken between the external device and head module in
case of a communication failure.
● Analog outputs may remain on due to a failure of the module. Configure an external interlock circuit
for output signals that could cause a serious accident.

[Design Precautions]
WARNING
● Do not write any data to the "system area" and "write-protect area" (R) of the buffer memory in the
intelligent function module. Also, do not use any "use prohibited" signals as an output signal from the
head module to the intelligent function module. Doing so may cause malfunction of the programmable
controller system.
● If a communication cable (such as a CC-Link dedicated cable) is disconnected, the network may be
unstable, resulting in a communication failure of multiple stations. Configure an interlock circuit in the
program to ensure that the entire system will always operate safely even if communications fail.
Failure to do so may result in an accident due to an incorrect output or malfunction.
[Design Precautions]
CAUTION
● Do not install the control lines or communication cables together with the main circuit lines or power
cables. Keep a distance of 100mm or more between them. Failure to do so may result in malfunction
due to noise.
● During control of an inductive load such as a lamp, heater, or solenoid valve, a large current
(approximately ten times greater than normal) may flow when the output is turned from off to on.
Therefore, use a module that has a sufficient current rating.
● At power-on, a voltage may occur or a current may flow between output terminals of the analog output
module for a moment. In this case, start the control after analog outputs become stable.
[Installation Precautions]
WARNING
● Shut off the external power supply (all phases) used in the system before mounting or removing a
module. Failure to do so may result in electric shock or cause the module to fail or malfunction.
[Installation Precautions]
CAUTION
● Use the head module in an environment that meets the general specifications in this manual. Failure
to do so may result in electric shock, fire, malfunction, or damage to or deterioration of the product.
● To interconnect modules, engage the respective connectors and securely lock the module joint levers
until they click. Incorrect interconnection may cause malfunction, failure, or drop of the module.
● Tighten the screws within the specified torque range. Undertightening can cause drop of the screw,
short circuit, or malfunction. Overtightening can damage the screw and/or module, resulting in drop,
short circuit, or malfunction.
● Do not directly touch any conductive parts and electronic components of the module. Doing so can
cause malfunction or failure of the module.
3
[Wiring Precautions]
WARNING
● Shut off the external power supply (all phases) used in the system before wiring. Failure to do so may
result in electric shock or cause the module to fail or malfunction.
● After installation and wiring, attach the included terminal cover to the module before turning it on for
operation. Failure to do so may result in electric shock.
[Wiring Precautions]
CAUTION
● Individually ground the FG terminal of the programmable controller with a ground resistance of 100
or less. Failure to do so may result in electric shock or malfunction.
● Use applicable solderless terminals and tighten them within the specified torque range. If any spade
solderless terminal is used, it may be disconnected when a terminal block screw comes loose,
resulting in failure.
● Check the rated voltage and terminal layout before wiring to the module, and connect the cables
correctly. Connecting a power supply with a different voltage rating or incorrect wiring may cause a fire
or failure.
● Connectors for external devices must be crimped or pressed with the tool specified by the
manufacturer, or must be correctly soldered. Incomplete connections may cause short circuit, fire, or
malfunction.
● Securely connect the connector to the module.
● Do not install the control lines or communication cables together with the main circuit lines or power
cables. Keep a distance of 100mm or more between them. Failure to do so may result in malfunction
due to noise.
● Place the cables in a duct or clamp them. If not, dangling cable may swing or inadvertently be pulled,
resulting in damage to the module or cables or malfunction due to poor contact.
● Check the interface type and correctly connect the cable. Incorrect wiring (connecting the cable to an
incorrect interface) may cause failure of the module and external device.
● Tighten the terminal block screws within the specified torque range. Undertightening can cause short
circuit, fire, or malfunction. Overtightening can damage the screw and/or module, resulting in drop,
short circuit, fire, or malfunction.
● When disconnecting the cable from the module, do not pull the cable by the cable part. For the cable
with connector, hold the connector part of the cable. For the cable connected to the terminal block,
loosen the terminal screw. Pulling the cable connected to the module may result in malfunction or
damage to the module or cable.
● Prevent foreign matter such as dust or wire chips from entering the module. Such foreign matter can
cause a fire, failure, or malfunction.
● A protective film is attached to the top of the module to prevent foreign matter, such as wire chips,
from entering the module during wiring. Do not remove the film during wiring. Remove it for heat
dissipation before system operation.

[Wiring Precautions]
CAUTION
● When connecting a CC-Link system master/local module to the head module, use CC-Link dedicated
cables for the CC-Link system. If not, the performance of the CC-Link system is not guaranteed. For
the station-to-station cable length and the maximum overall cable length, follow the specifications in
the MELSEC-L CC-Link System Master/Local Module User's Manual. If not, normal data transmission
is not guaranteed.
● When the high-speed counter module is connected to the head module, ground the shield cable on
the encoder side (relay box). Always ground the FG and LG terminals to the protective ground
conductor. Failure to do so may cause malfunction.
● Mitsubishi programmable controllers must be installed in control panels. Connect the main power
supply to the power supply module in the control panel through a relay terminal block. Wiring and
replacement of a power supply module must be performed by qualified maintenance personnel with
knowledge of protection against electric shock. For wiring methods, refer to the MELSEC-L CPU
Module User's Manual (Hardware Design, Maintenance and Inspection).
[Startup and Maintenance Precautions]
WARNING
● Do not touch any terminal while power is on. Doing so will cause electric shock or malfunction.
● Shut off the external power supply (all phases) used in the system before cleaning the module or
retightening the terminal block screws or connector screws. Failure to do so may result in electric
shock.
[Startup and Maintenance Precautions]
CAUTION
● Before performing online operations (especially, program modification, forced output, and operating
status change) for the running head module from the peripheral connected, read relevant manuals
carefully and ensure the safety. Improper operation may damage machines or cause accidents.
● Do not disassemble or modify the module. Doing so may cause failure, malfunction, injury, or a fire.
● Use any radio communication device such as a cellular phone or PHS (Personal Handy-phone
System) more than 25cm away in all directions from the programmable controller. Failure to do so
may cause malfunction.
● Shut off the external power supply (all phases) used in the system before mounting or removing a
module. Failure to do so may cause the module to fail or malfunction.
● Tighten the terminal block screws or connector screws within the specified torque range.
Overtightening can damage the screw and/or module, resulting in drop, short circuit, or malfunction.
● After the first use of the product (module and terminal block), do not connect/disconnect the product
more than 50 times (in accordance with IEC 61131-2). Exceeding the limit may cause malfunction.
● Before handling the module, touch a conducting object such as a grounded metal to discharge the

(2) Data setting method
In Network Configuration Setting of the master station, set the total number of points for the input/output (X/Y) of
the modules connected to the head module, in 16-point units.
In the case of the figure on the previous page, specify "0000" to "003F" for "RX/RY Setting".
● To set an empty slot on the intelligent device station or to change a start I/O number, modify the data in the I/O
Assignment setting of the head module.
● If the number of points will be increased for a system expansion in future, for example, set a large number for "RX/RY
Setting" in Network Configuration Setting of the master station. Doing so will eliminate the need to change the parameter
setting of the master station at the time of the system expansion. However, increasing the number of points also
increases the processing time.

CHAPTER 11 TROUBLESHOOTING
(2) Precautions
(a) When the time and date of the error is not correctly displayed
• Check if the master station is connected to the head module. The head module periodically collects time
information from the CPU module on the master station. If the master station is not connected to the head
module, the time and date of errors will not be displayed correctly. (Initial value: 2000/01/01 00:00:00)
• After acquisition of clock information from the master station, if the head module is powered off and on, the
clock will restart from the time of the power off. (The clock pauses during power off.)
11
Because of this, the displayed time and date of the error occurred during initial processing may be different
from the actual time and date.
(b) When the error code is not correctly displayed
If errors occur frequently, "*HST.LOSS*" may be displayed in the "Error Code" column, instead of an error code.
(c) When no error history is displayed
Check if the "Module Error History Collection (Intelligent Function Module)" is selected in the "PLC RAS"
setting of PLC parameter. This setting is enabled by executing the write to PLC function using GX Works2 and
resetting the head module or powering off and on the system.
Select the
checkbox.

CHAPTER 11 TROUBLESHOOTING
(2) Error codes (4000H to 4FFFH)
If an error occurs at communication request from the programming tool, intelligent function module, or network
system connected, the head module returns the error code (any of 4000H to 4FFFH) to the request source.
This error code is not stored in SD0 because the error is not the one detected by the self-diagnostic function of
the head module.
When the request source is a programming tool, a message and an error code are displayed on the programming
tool. When the request source is an intelligent function module or network system, the head module returns an
11
error code to the request source.
For messages, details, causes, and actions of errors, refer to the following.

Regardless of the remote output (RY) that was
transmitted cyclically, "on" is output externally.
Forced off registration
The remote input (RX) assigned to the input (X) is
transmitted cyclically in a forced off-status.
Regardless of the remote output (RY) that was
transmitted cyclically, "off" is output externally.

• The on status of the 0 bit in Debug function usage (SD840)
(c) Forcibly turning on/off from multiple GX Works2
Forced on/off can be registered from multiple GX Works2 to a single head module. In this case, the last
registration is effective. For this reason, the GX Works2 that executed the forced on/off may display an on/off
information that is different from that of the head module. When the forced on/off registration is performed from
multiple GX Works2, click the
button to update the data, and then execute the function.
(d) Status of devices after forced on/off registration data are canceled
When the on/off registration information of the following input (X) and output (Y) are canceled, the forced on/off
status is retained.
• Of the inputs (X) in the range of unattached modules, input (X) that is outside the refresh range with CCLink
• Output (Y) that is outside the range that was set in "RX/RY Setting" of Network Configuration Setting of the
master station
(e) Status of the head module
The REM. LED of the head module flashes.
Forced on/off can be registered regardless of the operating status (RUN/STOP).
If an error occurs in the head module, output (Y) cannot be turned on.
(f) Target input/output
• Input/output (X/Y) of the connected modules
• Input/output (X/Y) of the head module that corresponds to the refresh range of the remote input/output
(RX/RY) of the connected CC-Link master/local module

EMC and Low Voltage Directives
A
Compliance with the EMC Directive, which is one of the EU directives, has been mandatory for products sold within EU
member states since 1996 as well as compliance with the Low Voltage Directive since 1997.
For products compliant to the EMC and Low Voltage Directives, their manufacturers are required to declare
compliance and affix the CE marking.

The sales representative in EU member states is:
Company: Mitsubishi Electric Europe BV
Address: Gothaer Strasse 8, 40880 Ratingen, Germany
Appendix 9.1
Measures to comply with the EMC Directive
The EMC Directive sets requirements for emission (conducted and radiated electromagnetic interference emitted by a
product) and immunity (the ability of a product not to be influenced by externally generated electromagnetic
interference).
This section describes the precautions for machinery constructed with the MELSEC-L series modules to comply with
the EMC Directive.
These precautions are based on the requirements of the EMC Directive and the harmonized standards. However, they
do not guarantee that the entire machinery constructed according to the descriptions complies with the EMC Directive.
The manufacturer of the machinery must determine the testing method for compliance and declare conformity to the
EMC Directive.

Programmable controller is an open-type device intended to be placed in a conductive control panel or similar type of
enclosure. The tests were conducted with the programmable controller installed in a control panel.
The accuracy of an analog-digital converter module may temporarily vary within 10%.
(2) Installation in a control panel
Programmable controller is an open-type device intended to be placed in a conductive control panel or similar
type of enclosure.*1
This ensures safety as well as effective shielding of electromagnetic noise emitted from the programmable
controller.
*1
Remote modules on each network must be also installed inside the control panel. Waterproof type remote modules can
be installed outside the control panel.
(a) Control panel
• Use a conductive control panel.
• Mask off an area used for grounding in advance.
• To ensure electrical contact between inner plates and the control panel, mask off the bolt installation areas
of each inner plate so that conductivity can be ensured in the largest area.
• Ground the control panel with a thick ground cable so that low impedance can be ensured even at high
frequencies.
136
APPENDICES
• Keep the diameter of the holes on the control panel to 10cm or less. If the diameter is larger than 10cm,
electromagnetic wave may leak. In addition, because electromagnetic wave leaks through a clearance
between the control panel and its door, reduce the clearance as much as possible. Use of EMI gaskets
A
(sealing the clearance) can suppress undesired radiated emissions.
The tests were conducted by Mitsubishi Electric Corporation using a control panel having damping
characteristics of 37dB (maximum) and 30dB (average) (measured at 3m distance, 30 to 300MHz).
(b) Power cable and ground cable
• Provide a ground point to the control panel near the power supply module. Ground the LG and FG
terminals of the power supply module to the ground point with the thickest and shortest ground cable
possible (30cm or shorter).
(3) CC-Link IE Field Network cable
The precautions for using CC-Link IE Field Network cables are described below.
• For CC-Link IE Field Network module, use CC-Link IE Field Network cables (SC-E5EW-SM, manufactured
by Mitsubishi Electric System & Service Co., Ltd.).
• A CC-Link IE Field Network cable is a shielded cable. Strip a part of the jacket of the cable as shown below
and ground the exposed shield to the largest area.
CC-Link IE Field Network cable
Shield
• Use shielded cables for external wiring and ground the shields of the shielded cables to the control panel
with an AD75CK cable clamp (manufactured by Mitsubishi). (Ground the shields within 20 to 30cm from the
module.)

(4) Cables used for the modules connected to the head module
When a cable connected to a module such as an I/O module is extended out of the control panel, use a shielded
cable.
If a shielded cable is not used or not grounded properly, the noise immunity will not meet the requirement.
(a) Grounding a shielded cable
• Ground the shield of a shielded cable as close to the module as possible so that the grounded cable will
not be affected by electromagnetic induction from ungrounded cables.
• Ground the exposed shield to a large area on the control panel. A clamp can be used as shown below. In
this case, mask off the inner wall surface of the control panel, which comes in contact with the clamp.
Screw
Clamp fitting
Paint mask
Shielded cable
● Do not use the tip of a PVC wire soldered onto a shield of the shielded cable for grounding. Doing so will raise the highfrequency impedance, resulting in loss of the shielding effect.

(a) Ferrite core
A ferrite core is effective for reducing radiated noise in the 30MHz to 100MHz frequency band.
It is recommended to install a ferrite core if a shield cable extended out of the control panel does not provide
sufficient shielding effects.
Install a ferrite core to the cable in the position just before the cable is extended out of the control panel. If the
installation position is not appropriate, the ferrite core will not produce any effect.
Install a ferrite core to each power cable as shown below.

Measures to comply with the Low Voltage Directive
A
The Low Voltage Directive requires electrical equipment that is designed or adapted for use between 50 to 1000VAC
or 75 to 1500VDC to satisfy the safety requirements.
This section describes the precautions for use of the MELSEC-L series modules to comply with the Low Voltage
Directive.
These precautions are based on the requirements of the Low Voltage Directive and the harmonized standards.
However, they do not guarantee that the entire machinery constructed according to the descriptions complies with the
Low Voltage Directive. The manufacturer of the machinery must determine the testing method for compliance and
declare conformity to the Low Voltage Directive.
(1) Standard applied to MELSEC-L series modules
• EN61010-1 "Safety requirements for electrical equipment for measurement, control and laboratory use"
The MELSEC-L series modules that operate at 50VAC/75VDC or higher rated input voltage have also been
developed in accordance with EN61010-1.
However, the modules which operate at less than 50VAC/75VDC rated input voltage are not targeted for the Low
Voltage Directive compliance.
For CE-marked products, please consult your local Mitsubishi representative.
(2) Selecting MELSEC-L series products
(a) Power supply modules
Power supply modules which operate at 100VAC or 200VAC rated input voltage have hazardous voltage (peak
voltage higher than or equal to 42.4V) internally. Therefore, insulation between the primary and secondary
(b) I/O modules
I/O modules which operate at 100VAC or 200VAC rated input voltage have hazardous voltage (peak voltage
higher than or equal to 42.4V) internally. Therefore, insulation between the primary and secondary circuits is
reinforced for CE-marked I/O modules.
I/O modules which operate at 24VDC or less rated input voltage are not targeted for the Low Voltage Directive
compliance.
(c) GOT
Use a CE-marked GOT.
(d) Products not subject to the Low Voltage Directive
The following products are not targeted for the Low Voltage Directive compliance because the circuits in the
products operate at the voltage of 5VDC or less.
• Head module
• END cover
Intelligent function modules are also not targeted for the Low Voltage Directive compliance because the rated
voltage of the modules is 24VDC or less.
(3) Power supply
Power supply modules are designed to meet the overvoltage category .
Confirm that the power supply to a programmable controller meets the overvoltage category .
145
Appendix 9 EMC and Low Voltage Directives
Appendix 9.2 Measures to comply with the Low Voltage Directive
circuits is reinforced for CE-marked power supply modules.
(4) Control panel
(a) Protection against electric shock
Handle the control panel as follows to protect a person who does not have adequate knowledge of electrical
installation from an electric shock.
• Lock the control panel so that only a person who is trained and has acquired enough knowledge of
electrical installation can open the panel.
• Design the control panel so that the power supply is automatically shut off when the panel is opened.
• Use a control panel with a protection degree of IP20 or higher.
(b) Protection from dust and water
The control panel needs to be dustproof and waterproof.
Insufficient dustproof and waterproof lower the dielectric withstand of the control panel, possibly causing
dielectric breakdown.
The insulation of Mitsubishi programmable controllers is designed to be used in an environment of pollution
degree 2. Use them in an environment of pollution degree 2 or below. The environment of pollution degree 2
can be achieved when the programmable controller is installed inside the control panel with a protection degree
of IP54 or equivalent.
(5) Grounding
The following two types of ground terminals are available.
Use the ground terminals in grounded status.

resistance.
Improves the noise resistance.
Functional grounding
(6) External wiring
(a) 24VDC external power supply
For 24VDC I/O modules or intelligent function modules requiring an external power supply, connect an external
power supply of which insulation between the 24VDC circuit section and the hazardous voltage circuit section
is reinforced.
(b) External devices
For external devices connected to a programmable controller, use the one of which insulation between the
interface circuit section to the programmable controller and the hazardous voltage circuit section is reinforced
(if the device internally has a hazardous voltage circuit section).
(c) Reinforced insulation
Reinforced insulation means an insulation having the following withstand voltage.
Rated voltage of hazardous voltage
Surge withstand voltage (1.2/50s)
150VAC or less
2500V
300VAC or less

Appendix 10 General Safety Requirements
A
When a programmable controller is powered on or off, normal control outputs may not be performed temporarily. This
is because there is a time lag for the power to be turned on between the programmable controller power supply and
the external power supply (especially, DC) for the control target. Normal control outputs also may not be performed
when the external power supply or the programmable controller fails.
In terms of fail-safe and to prevent any of these abnormal operations from leading to the entire network system failure,
configure safety circuits (such as emergency stop circuits, protection circuits, or interlock circuits, where abnormal
operation may result in mechanical damage or accidents) external to the programmable controller.
(1) Fail-safe measures for head module failure
A head module can detect its own hardware failures by the self-diagnostic function. However, failures which
occur in a part, such as an I/O control part, may not be detected.
In this case, depending on the failure, all input or output points may turn on or off, or normal operation and safety
of the control-target device may not be ensured.
Even though Mitsubishi programmable controllers are manufactured under strict quality control, they may fail due
to some reasons. Provide fail-safe circuits external to the programmable controller so that no machine is
damaged and no accident occurs.
Appendix 10 General Safety Requirements
147
Appendix 11 Calculating Heating Value of Programmable
Controller
The ambient temperature inside the control panel where a head module is installed must be 55 or less.
It is necessary to know the average power consumption (heating value) of the equipment and devices installed inside
the control panel when designing a heat release structure of the panel.
This section describes the calculation method of the average power consumption of a programmable controller
system.
Calculate a rise in ambient temperature inside the control panel according to the power consumption.
Appendix 11.1
Calculating the average power consumption
The total of the power consumption calculated for each block is the power consumption of the entire programmable
controller system.
W = WPW + W5V + W24V + WOUT + WIN + WS (W)
Calculate a heating value and a rise in ambient temperature inside the control panel according to the calculated power
consumption (W).
The calculation formula for a rise in ambient temperature inside the control panel is as follows.
T=
W
UA
W: Power consumption of the entire programmable controller system
A: Surface area inside the control panel []
U (=6): When the ambient temperature inside the control panel is uniformed using a fan
U (=4): When the air inside the control panel is not circulated
● If the temperature inside the control panel is expected to exceed the specified range, it is recommended to install a heat
exchanger to the panel to lower the temperature.
● If a general-purpose fan is used, dust will be sucked into the control panel with the external air. This may affect the
performance of the programmable controller.

Not applicable for the power supply module which does not have the 24VDC power output. (Power (24VDC) is externally
supplied.)
(2) Power consumption of the 5VDC logic circuit sections in all modules
(including the head module)
The power consumption of the 5VDC output circuit in the power supply module is the power consumption of each
module.
W5V = I5V  5 (W)
(3) Total of 24VDC average power consumption of the output modules (power
consumption for the output points simultaneously turned on)
W24V = I24V  24  Simultaneous on rate (W)
(4) Voltage drop in the output section of the output module (power consumption
for the output points simultaneously turned on)
WOUT = IOUT  Vdrop  Number of output points  Simultaneous on rate (W)
IOUT: Output current (current in actual use) (A)
Vdrop: Voltage drop of each output module (V)
(5) Average power consumption of input section in the input module (power
consumption for the input points simultaneously turned on)
WIN = IIN  E  Number of input points  Simultaneous on rate (W)
IIN: Input current (effective value for AC) (A)

Appendix 11 Calculating Heating Value of Programmable Controller
Appendix 11.1 Calculating the average power consumption
The average power of the 24VDC external power supply is the total power consumption of each module.
Appendix 12 Processing Time
The calculation formula for the I/O response time of the head module is as follows:
Rio = (Number of RX/RY points)  0.16 + (Number of RWw/RWr points)  5.5 + 430 + Ka + (Response time of the
connected module) [s]
The above formula calculates the average value when the number of RX/RY points is the same as the number of
actual I/O points of the module connected to the head module, and an auto refresh of the same number of points as
the number of RWw/RWr points was performed.
