[Startup and Maintenance Precautions]
WARNING
● Do not touch any terminal while power is on. Doing so will cause electric shock or malfunction.
● Correctly connect the battery connector. Do not charge, disassemble, heat, short-circuit, solder, or
throw the battery into the fire. Also, do not expose it to liquid or strong shock. Doing so will cause the
battery to produce heat, explode, ignite, or leak, resulting in injury and fire.
● Shut off the external power supply (all phases) used in the system before cleaning the module or
retightening the terminal screws, connector screws, or module fixing screws. Failure to do so may
result in electric shock.
[Startup and Maintenance Precautions]
CAUTION
● When connecting an external device with a CPU module or intelligent function module to modify data
of a running programmable controller, configure an interlock circuit in the program to ensure that the
entire system will always operate safely. For other forms of control (such as program modification,
parameter change, forced output, or operating status change) of a running programmable controller,
read the relevant manuals carefully and ensure that the operation is safe before proceeding. Improper
operation may damage machines or cause accidents.
● Do not disassemble or modify the modules. Doing so may cause failure, malfunction, injury, or a fire.
● Do not disassemble or modify the CFast cards. 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 the
module. Failure to do so may cause the module to fail or malfunction.
● After the first use of the product, do not perform each of the following operations more than 50 times
(IEC 61131-2/JIS B 3502 compliant).
Exceeding the limit may cause malfunction.
• Mounting/removing the module to/from the base unit
● 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.
● After the first use of the product, do not insert/remove the CFast card to/from the CPU module more
than 10,000 times. Exceeding the limit may cause malfunction.
● Do not touch the metal terminals on the back side of the SD memory card and CFast card. Doing so
may cause malfunction or failure of the module.
● 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. Wearing a grounded antistatic wrist strap is recommended.
Failure to discharge the static electricity may cause the module to fail or malfunction.
● Before handling the CFast card, touch a conducting object such as a grounded metal to discharge the
static electricity from the human body. Wearing a grounded antistatic wrist strap is recommended.
Failure to discharge the static electricity may cause the CFast card to fail or malfunction.
