PREPARATORY PROCEDURES AND SETTING
CAUTION
This section explains the items to be inspected daily or periodically to use the C Controller
system under normal and optimum conditions at all times.
Before performing online operations (especially program
modification, forced output, and operation status change), 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 (9.85
inches) away in all directions from the C Controller system.
Failure to do so may cause malfunction.
Shut off the external power supply for the system in all phases
before mounting or removing the module.
Failure to do so may cause the module to fail or malfunction.
After the first use of the product, do not mount/remove the module
to/from the base unit more than 50 times respectively (IEC 61131-2
compliant).
Exceeding the limit of 50 times may cause malfunction.
Do not drop or apply shock to the battery to be installed in the
module.
Doing so may damage the battery, causing the battery fluid to leak
inside the battery.
If the battery is dropped or any shock is applied to it, dispose of it
without using.
Before handling the module, touch a grounded metal object to
discharge the static electricity from the human body.
Failure to do so may cause the module to fail or malfunction.
