When using Mitsubishi equipment, thoroughly read this manual and the associated
manuals introduced in the manual. Also pay careful attention to safety and handle the
module properly.
These precautions apply only to Mitsubishi equipment. Refer to the user’s manual of the
CPU module to use for a description of the PLC system safety precautions.
These      SAFETY PRECAUTIONS      classify the safety precautions into two
categories: "DANGER" and "CAUTION".

Depending on circumstances, procedures indicated by 

CAUTION may also be linked

to serious results.
In any case, it is important to follow the directions for usage.
Store this manual in a safe place so that you can take it out and read it whenever
necessary.  Always forward it to the end user.

Conformance to the EMC Directive/Low Voltage Directive

When incorporating the Mitsubishi PLC into other machinery or equipment and keeping
compliance with the EMC and low voltage directives, refer to Chapter 3, "EMC
Directives and Low Voltage Directives" of the User's Manual (Hardware) included with
the CPU module or base unit used.
The CE logo is printed on the rating plate on the main body of the PLC that conforms to
the EMC directive and low voltage instruction.
By making this product conform to the EMC directive and low voltage instruction, it is not
necessary to make those steps individually.

This manual explains specifications and the names of the components for the
Q68DAV type D/A converter module (hereafter Q68DAV) and the Q68DAI
type D/A converter module (hereafter Q68DAI) which are used in combination
with the MELSEC-Q Series CPU module.  In this manual, both the Q68DAV
and Q68DAI are referred to as D/A converter modules.
After unpacking, confirm that the following products are enclosed.

(1) Do not drop the module or cause it to receive strong impact.
(2) Tighten the terminal screws for the module to the specified torque shown below.

Insufficient tightening torque could result in shorts, failures or malfunction.

(1) Use separate cables for the external output signal or external power supply

for the AC and D/A converter modules.  Take steps to prevent the AC side
from being affected by surge or inductance.

(2)  Ground one point of the shield for shielded wires or shielded cables.

If it is difficult to wire FG terminals due to the limited installation space, use FG terminal L-shaped metal fitting.

•  Do not bunch the control wires or communication cables with the main circuit or power

wires, or install them close to each other.

They should be installed 100 mm (3.94 inch) or more from each other.

Not doing so could result in noise that may cause malfunction.

•  At power ON/OFF, voltage or current may instantaneously be output from the output

terminal of this module.  In such case, wait until the analog output becomes stable to start

controlling the external device.

•  Use the PLC in an environment that meets the general specifications given in the User's

Manual of the CPU module being used.

Using this PLC in an environment outside the range of the general specifications may cause

electric shock, fire, malfunction, and damage to or deterioration of the product.

•  While pressing the installation lever located at the bottom of module, insert the module fixing tab into

the fixing hole in the base unit until it stops.

Improper installation may result in malfunction , breakdown or the module coming loose and

dropping.

Securely fix the module with screws if it is subject to vibration during use.

•  Tighten the screws within the range of specified torque.

If the screws are loose, it may cause the module to fallout, short circuits, or malfunction.

If the screws are tightened too much, it may cause damage to the screw and/or the module,

resulting in fallout, short circuits or malfunction.

•  Be sure to shut off all phases of the external power supply used by the system before mounting or

removing the module.

Not doing so may cause damage to the module.

•  Do not directly touch the conductive area or electronic components of the module.

Doing so may cause malfunction or failure in the module.

•  Always ground the FG terminal for the PLC.

There is a risk of electric shock or malfunction.

•  When turning on the power and operating the module after wiring is completed, always attach

the terminal cover that comes with the product.

There is a risk of electric shock if the terminal cover is not attached.

•  Tighten the terminal screws within the range of specified torque.

If the terminal screws are loose, it may result in short circuits or malfunction.

If the terminal screws are tightened too much, it may cause damage to the screw and/or the

module, resulting in short circuits or malfunction.

•  Be careful not to let foreign matters such as sawdust or wire chips get inside the module.

These may cause fires, failure or malfunction.

•  The top surface of the module is covered with protective film to prevent foreign objects such as

cable offcuts from entering the module when wiring.

Do not remove this film until the wiring is complete.

Before operating the system, be sure to remove the film to provide adequate heat ventilation.
