III - 1
In order that you can use C70 in normal and optimal condition at all times, this section describes those items
that must be maintained or inspected daily or at regular intervals.
● 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.
● 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 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 C70.
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.
