[Startup and Maintenance precautions]
CAUTION
The online operations performed from a PC to a running safety PLC (Program change when a safety
CPU is RUN, device test, and operating status change such as RUN-STOP switching) have to be
executed after the manual has been carefully read and the safety has been ensured.
Following the operating procedure predetermined at designing, the operation has to be performed by
an instructed person.
When changing a program while a safety CPU is RUN (Write during RUN), it may cause a program
breakdown in some operating conditions.
Fully understand the precautions described in the GX Developer's manual before use.
Do not disassemble or modify the modules.
Doing so could cause a failure, erroneous operation, injury, or fire.
If the product is repaired or remodeled by other than the specified FA centers or us, the warranty is
not covered.
Use any radio communication device such as a cellular phone or a PHS phone more than 25cm(9.85
inch) away in all directions of the PLC.
Not doing so can cause a malfunction.
Completely turn off the externally supplied power used in the system before mounting or
removingthe module.
Not doing so could result in damage to the product.
Restrict the mounting/removal of a module, base unit, and terminal block up to 50 times
(IEC61131-2-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 or give an impact to the battery mounted to the module.
Doing so may damage the battery, causing the battery fluid to leak inside the battery.
If the battery is dropped or given an impact, dispose of it without using.
Before touching the module, always touch grounded metal, etc. to discharge static electricity
fromhuman body, etc.
Not doing so can cause the module to fail or malfunction
