6. INSPECTION AND MAINTENANCE
Do not touch the terminals while power is on. Doing so could cause electric shock.
Correctly connect
the battery. Also, do not charge, disassemble, heat, place in fire, short circuit, or
solder the battery.
Mishandling of a battery may cause overheating, cracks or ignition which could result in injury and
fire.
Turn off the all lines of the power supply externally when cleaning the module, tightening the terminal
screws or module fixing screws. Not doing so could result in electric shocks.
Under tightening the terminal screws may cause a drop, short circuit or operation failure. Over
tightening may cause a drop, short circuit or operation failure due to damage to the screw or module.
Read the manual carefully and pay careful attention to safety for the on-line operation (especially
program change, forced stop or operation change) performed by connecting peripheral devices to
the CPU module during operation.
Erroneous operation may cause machine breakage or accident.
Never try to disassemble or modify module. It may cause product failure, operation failure, injury or
fire.
When using cellular phone, keep them away from the Motion controller 25 cm (9.84 inch) or more. It
may cause an operation failure.
Turn off the all lines of the power supply externally when installing or removing the modules. Not doing
