SAFETY PRECAUTIONS
(Always read these precautions prior to use.)
Before using this product, please read this manual carefully and pay full attention to safety to
ensure that the product is used correctly.
The precautions presented in this manual are concerned with this product only. For
Programmable Controller system safety precautions, refer to the following manuals.
・MELSEC-Q series: QCPU User’s Manual (SH-080483ENG)
・MELSEC iQ-R series: Safety Guidelines (IB-0800525E)
If the equipment is used in a manner not specified by the manufacturer, the protection provided
by the equipment may be impaired.
In this manual, the safety precautions are ranked as “WARNING” and “CAUTION.”
Indicates that incorrect handling may cause hazardous
conditions, resulting in death or severe injury.
WARNING
Indicates that incorrect handling may cause hazardous
conditions, resulting in medium or minor injury and/or
property damage.
CAUTION
Note that failure to observe the
CAUTION level instructions may lead to a serious
consequence according to the circumstances. Always follow the precautions of both levels
because they are important to personal safety.
Please keep this manual in an easy-to-access location for future reference, and be sure to
provide the manual to the end user.
[Precautions before using]
CAUTION
When making a switch to the MELSEC-Q Series or MELSEC iQ-R Series, be sure to
consult user's manual supplied with individual module under the MELSEC-Q Series or
MELSEC iQ-R Series module to confirm differences in various aspects including
performance, function, CPU input/output signals between the two modules.
[Installation Precautions]
CAUTION
Use the Conversion Adapter in the environmental conditions that are specified in the
general specification in the following manuals. If the Products are used in any
environment beyond the bounds of the general specification, electric shock, fire,
malfunction, or damage to or degradation of the Products will result.
・MELSEC-Q series: QCPU User’s Manual (SH-080483ENG)
・MELSEC iQ-R series: Safety Guidelines (IB-0800525E)
Do not directly touch any conductive parts of Conversion Adapter. Contact will cause
malfunction or failure in the system.
Fasten the Conversion Adapter and the Mounting Bracket securely with retaining
screws, and tighten the screws by applying torque within specified limits. Loose
screws can lead to the dropping of the Conversion Adapter or Mounting Bracket,
possibly causing breakage thereof. Excessive tightness of the screws can lead to
breakage of the screws, Conversion Adapter, Mounting Bracket, or MELSEC-Q Series
or MELSEC iQ-R Series Module, possibly causing the dropping, shorting, and
malfunction thereof.
Always check for correct match between MELSEC-Q Series or MELSEC iQ-R Series and
the Conversion Adapter. Incorrect match can cause damage to the MELSEC-Q Series
or MELSEC iQ-R Series Module.
When installing the Conversion Adapter, take care not to get your hand snagged on
the Mounting Bracket or the like. Injury may result.
When installing or removing the MELSEC-Q Series or MELSEC iQ-R Series Module
complete with a Converter Adapter, be sure to hold it with both hands. Dropping may
lead to breakage.
[Wiring Precautions]
WARNING
Before attempting to install the Unit or carry out the necessary wiring, make certain
that the external power supply, used in the system, is shut off on all three phases.
Failure to do so may result in electric shock or damage to the product
.
[Wiring Precautions]
WARNING
After installation and wiring, close the terminal block cover before turning on the
module for operation. Failure to do so may result in electric shock.
[Wiring Precautions]
CAUTION
Carry out wiring for the Conversion Adapter correctly after checking the specification
and terminal arrangement for the module used. Connecting a power supply with a
different voltage rating or incorrect wiring may cause a fire or failure.
Tighten the terminal installation screws and terminal screw securely by applying
torque within the specified limits. Loose screws will cause short circuit, fire or
malfunction. Excessive tightening will damage the screws or the Conversion Adapter
which in turn will cause dropping of parts, short circuit or malfunction.
Use care to prevent foreign materials including cuttings and wiring debris from
entering the Conversion Adapter or the MELSEC-Q Series or MELSEC iQ-R Series
Module. These will be cause for fire, failure or malfunction.
[Startup and Maintenance Precautions]
WARNING
Do not touch live terminals. There is a danger of electric shock or malfunction.
Shut off the external power supply for the system in all phases before cleaning or
retightening the terminal screws. Failure to do so may result in electric shock or cause
the MELSEC-Q Series or MELSEC iQ-R Series Module to fail or malfunction. Loose
screws can lead to dropping, shorting, and malfunction. Excessive tightness of the
screws can lead to breakage of the screws, Conversion Adapter, Mounting Bracket, or
MELSEC-Q Series or MELSEC iQ-R Series Module, possibly causing the dropping,
shorting, and malfunction thereof.
CAUTION
Do not modify the Conversion Adapter or take it apart. Doing so will cause failure,
malfunction, personal injury, or fire.
Do not drop the Conversion Adapter and Mounting Bracket or do not give a strong
impact to it. This will cause damage.
[Disposal Precautions]
CAUTION
When disposing of the product, treat it as industrial waste.

*1：Do not use or store under pressure higher than the atmospheric pressure of altitude 0m.
*2：This indicates the section of the power supply to which the equipment is assumed to be
connected between the public electrical power distribution network and the machinery within
premises.
Category II applies to equipment for which electrical power is supplied from fixed facilities.
*3：This index indicates the degree to which conductive material is generated in terms of the
environment in which the equipment is used.
Pollution level 2 is when only non-conductive pollution occurs. A temporary conductivity caused by
condensing must be expected occasionally.
