CAUTION
●
Individually ground the shielded cables of the programmable controller with a ground resistance of
100 ohms or less. Failure to do so may result in electric shock or malfunction.
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 it 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 (all phases) used in the system before cleaning the module or
retightening the terminal screws, connector screws, or module fixing screws. Failure to do so may
result in electric shock.
