SAFETY PRECAUTIONS
(Always read these instructions before using this equipment.)
Before using this product, please read this manual and the relevant manuals
introduced in this manual carefully and pay full attention to safety to handle the
product correctly.
The instructions given in this manual are concerned with this product. For the
safety instructions of the programmable controller system, please read the user's
manual for the CPU module to use
In this manual, the safety instructions are ranked as "DANGER" and "CAUTION".
Note that the " CAUTION" level may lead to a serious consequence according
to the circumstances. Always follow the instructions of both levels because they
are important to personal safety.
Please save this manual to make it accessible when required and always forward
it to the end user.
[Design Precautions]
Indicates that incorrect handling may cause
hazardous conditions, resulting in death or severe
injury.
Indicates that incorrect handling may cause
hazardous conditions, resulting in medium or slight
personal injury or physical damage.
CAUTION
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.
DANGER
CAUTION

A-2
[Installation Precautions]
CAUTION
Use the programmable controller in an environment that meets the general
specifications given in the User's Manual of the CPU module being used.
Using this programmable controller 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. After mounting the module to the base unit
securely hold the module with module fixing bracket.
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.

A-3
[Wiring Precautions]
CAUTION
Always ground the FG terminal for the programmable controller.
There is a risk of electric shock or malfunction.
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 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.

4. Handling Precautions
(1) Do not drop the module case or subject it to heavy impact.
(2) Do not remove the PCB of the module from its case.
Doing so may cause the module failure.
(3) Be careful not to let foreign matters such as sawdust or wire chips get
inside the module.
These may cause fires, failure or malfunction.
(4) 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.
(5) Before touching the module, always touch grounded metal, etc. to
discharge static electricity from human body, etc.
Not doing so can cause the module to fail or malfunction.
(6) Tighten the screws such as module fixing screws within the following
ranges. Loose screws may cause short circuits, mechanical failures or
malfunctions.
(7) 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.

4.1 Mounting module fixing bracket
Hold the Q66DA-G with module fixing bracket after the Q66DA-G is
mounted to the base unit.
POINT
Make sure that the module fixing bracket is hooked on the 3rd slit
viewed from the front of Q66DA-G.
And tighten the module fixing screw at the specified torque.

5. Wiring
5.1 Wiring precautions
(1) Use separate cables for the alternating-current control circuit and the
external output signals and external supply power of the Q66DA-G in
order to avoid AC surges and induction effects.
(2) Do not mount the cables close to or bundle them with the main circuit
line, a high-voltage cable or a load cable from other than the
programmable controller. This may increase the effects of noise,
surges and induction.
(3) Perform a one-point grounding for shielded lines and the shields of
shielded cables.
(4) When the wiring of the module mounted right to the Q66DA-G is
difficult, perform wiring after removing the Q66DA-G.

9
5.2 External wiring
(1) For voltage output
(2) For current output
*1:Use a twisted two-core shielded wire for the power wire.
*2:If there is noise or ripples in the external wiring, connect a 0.1 to 0.47 F25V
capacitor between the V+/I+ terminal and COM.
IMPORTANT
Q66DA-G needs to be powered on 30 minutes prior to operation for compliance to
the specification (accuracy).Therefore, power on 30 minutes prior to offset/gain
setting or after online module replacement.
