[Startup and Maintenance Precautions]
WARNING
●
Do not touch any terminal while power is on. Doing so will cause electric
shock or malfunction.
●
Correctly connect the battery connector. Do not charge, disassemble, heat,
short-circuit, solder, or throw the battery into the fire. Also, do not expose the
battery to liquid or strong shock. Doing so will cause the battery to produce
heat, explode, ignite, or leak, resulting in injury and fire.
●
Shut off the external power supply for the system in all phases before cleaning
the module or retightening the screws on the terminal block or connector
screws. Failure to do so may result in electric shock.
CAUTION
●
Before performing online operations (especially, program modification, forced
output, and operation status change) for a running CPU module from the
peripheral connected, 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 away in all directions from
the programmable controller. Failure to do so may cause malfunction.
●
Shut off the external power supply for the system in all phases before
connecting or disconnecting the module. Failure to do so may cause the
module to fail or malfunction.
●
Tighten the screws on the terminal block or connector screws within the
specified torque range. Undertightening can cause drop of parts or wires,
short circuit, or malfunction. Overtightening can damage the screw and/or
module, resulting in drop, short circuit, or malfunction.
●
After the first use of the module (including a display unit), the number of
module connections/disconnections is limited to 50 times. Exceeding the limit
(in accordance with IEC 61131-2) may cause malfunction.
●
After the first use of the product, the number of SD memory card
insertions/removals is limited to 500 times. Exceeding the limit may cause
malfunction.
