4. Precautions For Use
(1) Do not drop the module or subject it to strong impact.
(2) Always make sure to touch the grounded metal to discharge the electricity
charged in the body, etc., before touching the module.
Failure to do so may cause a failure or malfunctions of the module.
(3) Tighten the terminal screws for the module to the specified torque shown below.
Insufficient tightening torque could result in shorts, failures or malfunction.
Screw location Tightening torque range
Module mounting screw (M3 screw)
36 to 48 N · cm
Terminal block terminal screw (M3 screw)
42 to 58 N · cm
Terminal block mounting screw (M3.5 screw)
66 to 89 N · cm
5. Wiring
5.1 Wiring precautions
(1) Wire the external AC control circuit and the external input signal for Q64AD-
GH with the separate cables to prevent the influence of surge or induction
from AC side.
(2) Ground one point of the shield for shielded wires or shielded cables.

[DESIGN PRECAUTIONS]
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.
Otherwise, noise may occur and result in malfunction.
[INSTALLATION PRECAUTIONS]
CAUTION
•
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.
•
When installing the module, securely insert the module fixing tabs into the mounting holes of the
base unit while pressing the installation lever located at the bottom of the module downward.
Incorrect installation may result in malfunction or breakdown, or cause the module to loosen and
drop. 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.
•
Switch all phases of the external power supply off when mounting or removing the module.
Otherwise, the module may be damaged.
•
Do not directly touch the conductive area or electronic components of the module.
Otherwise, the module may malfunction or go down.
[WIRING PRECAUTIONS]
CAUTION
•
When turning on the power and operating the module after wiring is completed, always attach
the terminal cover included 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.
