[Startup and Maintenance Precautions]
● Shut off the external power supply (all phases) used in the system before mounting or removing a
module. Failure to do so may cause the module to fail or malfunction.
A module can be replaced online (while power is on) on any MELSECNET/H remote I/O station or in
the system where a CPU module supporting the online module change function is used.
Note that there are restrictions on the modules that can be replaced online, and each module has its
predetermined replacement procedure.
For details, refer to the relevant sections in the QCPU User's Manual (Hardware Design, Maintenance
and Inspection) and in the manual for the corresponding module.
● After the first use of the product, do not mount/remove the module to/from the base unit, and the
terminal block to/from the module, and do not insert/remove the extended SRAM cassette to/from the
CPU module more than 50 times (IEC 61131-2 compliant) respectively.
Exceeding the limit of 50 times may cause malfunction.
● After the first use of the product, do not insert/remove the SD memory card to/from the CPU module
more than 500 times. Exceeding the limit may cause malfunction.
● Do not drop or apply shock to the battery to be installed in the module.
Doing so may damage the battery, causing the battery fluid to leak inside the battery.
If the battery is dropped or any shock is applied to it, dispose of it without using.
● Before handling the module, touch a grounded metal object to discharge the static electricity from the
human body.
Failure to do so may cause the module to fail or malfunction.
[Disposal Precautions]
● 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 of the battery directive in EU member states, refer to the QCPU User's Manual (Hardware
Design, Maintenance and Inspection).)
[Transportation Precautions]
● When transporting lithium batteries, follow the transportation regulations.
(For details of the regulated models, refer to the QCPU User's Manual (Hardware Design,
Maintenance and Inspection).)
