 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 user’s manual of the MELSEC-Q Series CPU Module
to be used.
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, be sure to consult user's manual supplied with

individual module under the MELSEC-Q Series 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. 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.

 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 Module, possibly causing the dropping, shorting, and
malfunction thereof.

 Always check for correct match between MELSEC-Q Series and the Conversion Adapter.

Incorrect match can cause damage to the MELSEC-Q 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 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.

 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.

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 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
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 Module, possibly causing the dropping, shorting, and
malfunction thereof.

CAUTION

 Do not modify the Conversion Adapter or take it apart. Doing so will cause failu re, 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.

5．Mounting and Installation

5.1 Handling Precautions

(1) 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.

(2) Do not touch live terminals. There is a danger of electric shock or malfunction.
(3) Do not modify the Conversion Adapter or take it apart. Doing so will cause failure, malfunction,

personal injury, or fire.

(4) Do not touch the energized part of the Conversion Adaptor directly. Contact will cause

malfunction or failure in the system.

(5) 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, Converter Adaptor,
Mounting Bracket, or MELSEC-Q Series Module, possibly causing the dropping, shorting, and
malfunction thereof.

(6) Use care to prevent foreign materials including cuttings and wiring debris from entering the

Conversion Adapter or the MELSEC-Q Series Module. These will be cause for fire, failure or
malfunction.

(7) Do not drop the Conversion Adapter and Mounting Bracket or do not give a strong impact to it.

This will cause damage.

6.1 Installation Method

① Secure the Conversion Adapter Anchor Base to the Base Adapter or control panel using the

Conversion Adapter Anchor Base installation screws (M4  8) provided as an accessory. (Two
end locations)

② Remove the terminal block attached with the MELSEC-Q Series Module after loosening the

terminal block installation screws (2 places top and bottom).

Secure the Mounting Bracket to the Q Series Module using the Mounting Bracket fixing screws
[M3.5  6 (Conversion Adapter accessory); four upper/lower locations].

③ Mount the Conversion Adapter onto the Mounting Bracket.

④ Secure the Conversion Adapter using the Conversion Adapter installation screws (M3  30; 4

locations).

Precaution

Before tightening the installation screws, check that the Conversion Adapter has been
securely installed on the MELSEC-Q Series Module. Tightening the screws in floating-off state
or tilting state will damage the Conversion Adapter installation screws and the Mounting
Bracket.

⑤ Secure the Conversion Adapter using the Conversion Adapter bottom installation screw (M3 

20; 2 location).

⑥ Secure the terminal block of the MEMOCON-SC GL Series (2000 Series I/O) to the Conversion

Adapter with the terminal block installation screws (M3; two upper/lower locations).

6.2 Tightening Torque

Tighten the installation screws to the specified torque below. An inappropriate tightening torque could
cause the product to fall or result in a short circuit, product failure or malfunction.
