6. INSPECTION AND MAINTENANCE
DANGER
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.
Switch off all phases of the externally supplied power used in the system when cleaning the module or
retightening the terminal or module mounting screws.
Not doing so could result in electric shock.
Under tightening of terminal screws can cause a short circuit or malfunction.
Over tightening of screws can cause damages to the screws and/or the module, resulting in fallout,
short circuits, or malfunction.
The capacitor is mounted to the modules. Do not incinerate the modules so that the incineration of
capacitor may cause burst.
For disposal of the modules, request for specialized industrial waste disposal services who has
incineration facility.
CAUTION
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
Motion controller 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.
Use any radio communication device such as a cellular phone or a PHS phone more than 25cm (9.84
inch) away in all directions of the Motion controller.
Failure to do so may cause a malfunction.
Completely turn off the externally supplied power used in the system before installation or removing
the module. Not doing so could result in electric shock, damage to the module or operation failure.
Do not install/remove the module on to/from base unit or terminal block more than 50 times, 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 impact the battery installed to the module. Doing so may damage the battery, causing
battery liquid to leak in the battery.
Do not use the dropped or impacted battery, but dispose of it.
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.
In order that you can use the Motion controller in normal and optimal condition at all
times, this section describes those items that must be maintained or inspected daily or
at regular intervals.
