[Design Instructions]
!
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 100mm(3.9inch) or more from each other.
Not doing so could result in noise that may cause malfunction.
•
When using the module while values, such as buffer memory set values, are registered in the
Flash ROM, do not turn off the power supply for the module loading station nor reset the PLC
CPU.
If the power supply for the module loading station is turned off or the PLC CPU is reset while any
values are registered, the data contents in the Flash ROM become inconsistent and as a result the
values must be set again in the buffer memory, etc. and reregistered to the Flash ROM.
Also, this may cause failure and malfunction of the module.
[Installation Instructions]
!
CAUTION
•
Use the PLC in an environment that meets the general specifications contained in the user's
manual of the CPU module to use.
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. Then, securely mount the module with the fixing
hole as a supporting point.
If the module is not installed properly, it may cause the module to malfunction, fail or fall off.
Secure the module with screws especially when it is used in an environment where constant
vibrations may occur.
•
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.
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.
