Before performing online operations (especially, program modification, forced output, and
operating status change) for the running CPU module on another station from GX Works2 over
CC-Link IE Field Network, read relevant manuals carefully and ensure the safety. 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.
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 screw within the specified torque range. Undertightening can cause drop of the
screw, short circuit or malfunction. Overtightening can damage the screw and/or module,
resulting in drop, short circuit, or malfunction.
Perform the daily and periodic inspections according to the instruction manual.
Perform maintenance and inspection after backing up the program and parameters for the
module and servo amplifier.
Do not place fingers or hands in the clearance when opening or closing any opening.
Periodically replace consumable parts such as batteries according to the instruction manual.
Do not touch the lead sections such as ICs or the connector contacts.
Before touching the module, always touch grounded metal, etc. to discharge static electricity from
human body. Failure to do so may cause the module to fail or malfunction.
Do not directly touch the module's conductive parts and electronic components.
Touching them could cause an operation failure or give damage to the module.
Do not place the module or servo amplifier on metal that may cause a power leakage or wood,
plastic or vinyl that may cause static electricity buildup.
Do not perform a megger test (insulation resistance measurement) during inspection.
When replacing the module or servo amplifier, always set the new module settings correctly.
