[Startup/Maintenance Precautions]
 Never disassemble or modify the module.
This may cause failure, malfunctions, injuries or a fire.
 Before mounting/dismounting the module, be sure to shut off all phases of external power supply
used by the system.
Failure to do so may cause failure or malfunctions of the module.
 Do not mount/remove the module onto/from base unit more than 50 times (IE C61131-2
compliant), after the first use of the product.
Failure to do so may cause the module to malfunction due to poor contact of connector.
 Do not drop the battery installed to the module, and do not give it a shock.
Doing so may damage the battery, causing battery fluid leakage in the battery.
If the battery has been dropped or given a shock, do not use it but dispose of it.
 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.
[Operating Precautions]
 Before controlling a running programmable controller (e.g. modifying data), fully ensure safety.
 Do not write any data into the "System area" of the buffer memory of the intelligent function
module.
Also, do not output (turn on) the "Use prohibited" signal, which is one of the output signals from
the programmable controller CPU to the intelligent function module.
If data is written to the "System area" or the "Use prohibited" signal is output, there is a risk that
the programmable controller system may malfunction.
[Disposal Precautions]
 Dispose of this product as industrial waste.
When disposing of batteries, separate them from other wastes according to the local
regulations.
(For details of the battery directive in EU member states, refer to Appendix 9.)
[Transportation Precautions]
 When transporting lithium batteries, make sure to treat them based on the transport regulations.
(Refer to Appendix 8 for details of the controlled models.)
