z
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.
Incorrect loading of the module can cause a malfunction, failure or drop.
When using the programmable controller in the environment of much
vibration, tighten the module with a screw.
Tighten the screw in the specified torque range.
Undertightening can cause a drop, short circuit or malfunction.
Overtightening can cause a drop, short circuit or malfunction due to damage
to the screw or module.
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.
z
For remote I/O stations of function version D or later, online module change
can be performed. However, the modules which can be replaced online are
limited, and replacement procedures are determined for each module.
For details, refer to the Q Corresponding MELSECNET/H Network System
Reference Manual (Remote I/O network).
z
Do not directly touch the module's conductive parts or electronic
components.
Touching the conductive parts could cause an operation failure or give
damage to the module.
z
Before touching the module, always touch grounded metal, etc. to discharge
static electricity from human body, etc. Not doing so can cause the module
