POINT

1. A1S68DAV and Q68DAVN differ from each other in the way input/output signals (X,

Y) and buffer memory addresses are allocated. Therefore, you need make

necessary changes to the sequence program that is used.

3. Mounting and Installation

3.1 Handling Instructions

(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 Adaptor 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 Adaptor , the Fittings and the Base Adaptor securely with retaining screws,

and tighten the screws by applying torque within specified limits. Loose screws can lead to the

dropping of the converter adaptor, fittings, or base adaptor, possibly causing breakage thereof.

Excessive tightness of the screws can lead to breakage of the screws, converter adaptor, fittings,

base adaptor, 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 Adaptor or the MELSEC-Q Series module. These will be cause for fire, failure or

malfunction.

(7) Do not drop the Conversion Adaptor, Fittings and the Base Adaptor, and avoid giving a strong

impact to them. Otherwise, breakage will result.

(8) If the existing system is installed on a DIN rail, the Base Adaptor is not necessary. The MELSEC-Q

Series Base Module you use can be mounted onto the DIN rail.

3.2 Instructions for Use

Because the module is reduced in width dimension (34.5mm→27.4mm) and thus in

area available for wiring, check dimensional data before installing the module.

4.1 Installation Procedure

[1] Secure the MELSEC-Q Series Base Module to the Base Adaptor with the supplied attaching

screws (M4 x 10). (Secure it in four places.)

[2] Mount a compatible module under the MELSEC-Q Series onto the MELSEC-Q Series Base

Module.

Also, remove the terminal block installed to the MELSEC-Q Series Module by undoing the terminal

block attaching screws (one at the top and the other at the bottom).

（Secure it in two places, top and bottom.）

[3] Secure the mounting bracket to a compatible module under the MELSEC-Q Series with retaining

screws (M3.5 x 6). (Secure it in two places, top and bottom.)

[4] Mount the Conversion Adaptor onto the mounting bracket and secure it with the Conversion

Adaptor attaching screws (M3 x 25). (Secure it in two places, top and bottom.)

[5] Secure the Base Adaptor to the panel with the supplied attaching screws (M5 x 12).

(Secure it in four places.)

[6] Secure the MELSEC-AnS Series terminal block to the Conversion Adaptor with the supplied

attaching screws (M4).

[7] Remove the terminal block cover from the MELSEC-AnS Series terminal block and fit the terminal

block cover supplied with the Conversion Adaptor in place.

4.2 Tightening Torque

Tighten the module attaching screws by applying torque listed in the table blow. Application of

improper tightening torque will cause dropping, short-circuit, failure, or malfunction.
