[STARTUP AND MAINTENANCE PRECAUTIONS]
WARNING
Do not touch any terminal during power distribution.
Doing so may cause an electric shock.
Properly connect batteries. Do not charge, disassemble, heat or throw them
into the fire and do not make them short-circuited and soldered. Incorrect
battery handling may cause personal injuries or a fire due to exothermic heat,
burst and/or ignition.
Be sure to shut off all phases of the external power supply used by the
system before cleaning or retightening the terminal screws or module
mounting screws.
Failure to do so may result in an electric shock.
If they are too loose, it may cause a short circuit or malfunctions.
If too tight, it may cause damage to the screws and/or module, resulting in an
accidental drop of the module, short circuit or malfunctions.
CAUTION
When performing online operations (especially, program modification, forced
output or operating status change) by connecting a peripheral device to the
running CPU module, read the manual carefully and ensure the safety.
Incorrect operation will cause mechanical damage or accidents.
Do not disassemble or modify each of modules.
Doing so may cause failure, malfunctions, personal injuries and/or a fire.
When using a wireless communication device such as a mobile phone, keep
a distance of 25cm (9.84inch) or more from the programmable controller in all
directions.
Failure to do so may cause malfunctions.
Be sure to shut off all phases of the external power supply used by the
system before mounting or removing the module.
Failure to do so may result in failure or malfunctions of the module.
Do not drop or apply any impact to the battery.
Doing so may damage the battery, resulting in electrolyte spillage inside the
battery.
If any impact has been applied, discard the battery and never use it.
Do not install/remove the terminal block more than 50 times after the first use
of the product. (IEC 61131-2 compliant)
Before handling modules, touch a grounded metal object to discharge the
static electricity from the human body.
Failure to do so may cause failure or malfunctions of the module.
