SAFETY PRECAUTIONS
(Read these precautions before using this product.)
Before using this product, please read this manual and the relevant manuals carefully and pay full attention
to safety to handle the product correctly.
The precautions given in this manual are concerned with this product only. For the safety precautions of the
programmable controller system, refer to the user's manual for the CPU module used.
In this manual, the safety precautions are classified into two levels: " WARNING" and " CAUTION".
Under some circumstances, failure to observe the precautions given under " CAUTION" may lead to
serious consequences.
Observe the precautions of both levels because they are important for personal and system safety.
Make sure that the end users read this manual and then keep the manual in a safe place for future
reference.
[Design Precautions]
[Design Precautions]
WARNING
●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.
●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 programmable controller
CPU to the intelligent function module.
Doing so may cause malfunction of the programmable controller system.
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.
●At power-on, a voltage may occur or a current may flow between output terminals for a moment. In
this case, start the control after analog outputs become stable.
●Power on or off the external power supply while the programmable controller is on. Failure to do so
may result in incorrect output or malfunction.
WARNING
CAUTION
Indicates that incorrect handling may cause hazardous conditions,
resulting in death or severe injury.
Indicates that incorrect handling may cause hazardous conditions,
resulting in minor or moderate injury or property damage.

[Installation Precautions]
[Installation Precautions]
[Wiring Precautions]
[Wiring Precautions]
WARNING
●Shut off the external power supply for the system in all phases before connecting or removing a
module. Failure to do so may result in electric shock or cause the module to fail or malfunction.
CAUTION
●Use the programmable controller in an environment that meets the general specifications in the
manual "Safety Guidelines", the manual supplied with the CPU module or head module. 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. Incorrect interconnection may cause malfunction, failure, or drop of the module.
●Tighten the screw 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.
WARNING
●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.
CAUTION
●Ground the FG terminal to the protective ground conductor dedicated to the programmable
controller. Failure to do so may result in electric shock or malfunction.
●Tighten the terminal block screw 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.
●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]
[Startup and Maintenance Precautions]
[Startup and Maintenance Precautions]
[Disposal Precautions]
CAUTION
●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).
WARNING
●Do not touch any terminal while power is on. Doing so will cause electric shock or malfunction.
●Shut off the external power supply for the system in all phases before cleaning the module or
retightening the terminal block screw. Failure to do so may result in electric shock.
CAUTION
●Do not disassemble or modify the module. Doing so may cause failure, malfunction, injury, or a fire.
●Shut off the external power supply for the system in all phases before connecting or removing a
module. Failure to do so may cause the module to fail or malfunction.
●Tighten the terminal block screw within the specified torque range. Undertightening can cause drop
of the component or wire, short circuit, or malfunction. Overtightening can damage the screw and/or
module, resulting in drop, short circuit, or malfunction.
●After the first use of the product (module, display unit, and terminal block), the number of
connections/disconnections is limited to 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
static electricity from the human body. Failure to do so may cause the module to fail or malfunction.
CAUTION
●When disposing of this product, treat it as industrial waste.
