[Startup and Maintenance Precautions]
CAUTION
● Startup and maintenance of a control panel must be performed by qualified maintenance personnel
with knowledge of protection against electric shock. Lock the control panel so that only qualified
maintenance personnel can operate it.
● Before handling the module, touch a conducting object such as a grounded metal to discharge the
static electricity from the human body. Failure to do so may cause the module to fail or malfunction.
● When connecting an external device with a remote head module to modify data of a running
programmable controller, configure an interlock circuit in the program of the master station to ensure
that the entire system will always operate safely. For other forms of control (such as parameter
change, forced output, or operating status change) of a running remote head module, read the
relevant manuals carefully and ensure that the operation is safe before proceeding. Improper
operation may damage machines or cause accidents.
● Especially, when a remote head module is remotely controlled by an external device, immediate
action cannot be taken if a problem occurs in the remote head module due to a communication failure.
To prevent this, configure an interlock circuit in the program of the master station, and determine
corrective actions to be taken between the external device and remote head module in case of a
communication failure.
[Operating Precautions]
CAUTION
● When changing data and operating status, and modifying program of the running programmable
controller from an external device such as a personal computer connected to an intelligent function
module, read relevant manuals carefully and ensure the safety before operation. Incorrect change or
modification may cause system malfunction, damage to the machines, or accidents.
● Do not power off the programmable controller or reset the CPU module while the setting values in the
buffer memory are being written to the flash ROM in the module. Doing so will make the data in the
flash ROM undefined. The values need to be set in the buffer memory and written to the flash ROM
again. Doing so can cause malfunction or failure of the module.
[Disposal Precautions]
CAUTION
● When disposing of this product, treat it as industrial waste.
● When disposing of batteries, separate them from other wastes according to the local regulations. For
details on battery regulations in EU member states, refer to the MELSEC iQ-R Module Configuration
Manual.
