[Startup and Maintenance Precautions]
● Before performing online operations (especially, program modification, forced output, and operating
status change) for the running CPU module from the peripheral connected, read relevant manuals
carefully and ensure the safety. Improper operation may damage machines or cause accidents.
● Do not disassemble or modify the module. Doing so may cause failure, malfunction, injury, or a fire.
● Use any radio communication device such as a cellular phone or PHS (Personal Handy-phone
System) more than 25cm away in all directions from the programmable controller. Failure to do so
may cause malfunction.
● 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.
● Tighten the terminal block screws within the specified torque range. Undertightening can cause drop
of the component or wire, short circuit, or malfunction. Overtightening can damage the screw and/or
module, resulting in drop, short circuit, or malfunction.
● After the first use of the product (module, display unit, and terminal block), the number of
connections/disconnections is limited to 50 times (in accordance with IEC 61131-2). Exceeding the
limit may cause malfunction.
● After the first use of the SD memory card, do not insert/remove the memory card 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 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.
● Before testing the operation by the positioning function, set a low speed value for the speed limit
parameter so that the operation can be stopped immediately upon occurrence of a hazardous
condition.
[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 on battery regulations in EU
member states, refer to the MELSEC-L CPU Module User's Manual (Hardware Design, Maintenance
and Inspection).)
[Transportation Precautions]
● When transporting lithium batteries, follow the transportation regulations. (For details on the regulated
models, refer to the MELSEC-L CPU Module User's Manual (Hardware Design, Maintenance and
Inspection).)
