[INSTALLATION PRECAUTIONS]
CAUTION
z
Use the programmable controller in an environment that meets the general specifications
contained in the CPU user's manual to use.
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.
z
When installing the module, securely insert the module fixing tabs into the mounting
holes of the base module while pressing the installation lever located at the bottom of the
module downward.
Improper installation may result in malfunction, breakdown or dropping out of the module.
Securely fix the module with screws if it is subject to vibration during use.
z
Tighten the screws within the range of specified torque.
If the screws are loose, it may cause 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.
z
Completely turn off the externally supplied power used in the system before mounting or
removing the module.
Not doing so could result in damage to the product.
Not doing so may cause electric shock or damage to the module.
z
Do not directly touch the conductive area or electronic components of the module.
Doing so may cause malfunction or failure in the module.
[WIRING PRECAUTIONS]
CAUTION
z
Perform correct pressure-displacement, crimp-contact or soldering for connector wire
connections using the tools specified by the manufactures.
Attach connectors to the module securely.
z
Be careful not to let foreign matters such as sawdust or wire chips get inside the module.
These may cause fires, failure or malfunction.
z
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.
z
Be sure to fix communication cables or power supply cables leading from the module by
placing them in the duct or clamping them.
Cables not placed in the duct or without clamping may hang or shift, allowing them to be
accidentally pulled, which may cause a module malfunction and cable damage.
z
When removing the communication cable from the module, do not pull the cable. When
removing the cable with a connector, hold the connector on the side that is connected to
the module.
Pulling the cable that is still connected to the module may cause malfunction or damage
to the module or cable.
z
Always ground the shielded cable on the encoder side (relay box).
Otherwise, malfunction may occur.
z
When wiring, be sure to verify the rated voltage of the product as well as the terminal
layout. Fire or failure may result if incorrect voltage is input or incorrect wiring is
performed.
z
Connecting terminals with incorrect voltage may result in malfunction or mechanical
failure.
