[Wiring Precautions]
CAUTION
● Prevent foreign matter such as dust or wire chips from entering the module. Such foreign matter can
cause a fire, failure, or malfunction.
● When a protective film is attached to the top of the module, remove it before system operation. If not,
inadequate heat dissipation of the module may cause a fire, failure, or malfunction.
● Programmable controllers must be installed in control panels. Connect the main power supply to the
power supply module in the control panel through a relay terminal block. Wiring and replacement of a
power supply module must be performed by qualified maintenance personnel with knowledge of
protection against electric shock. For wiring, refer to the MELSEC iQ-R Module Configuration Manual.
● For Ethernet cables to be used in the system, select the ones that meet the specifications in the user's
manual for the module used. If not, normal data transmission is not guaranteed.
[Precautions for using redundant function modules]
● For tracking cables to be used in the system, select the ones that meet the specifications in Page 78
Redundant Function Module. If not, normal data transmission is not guaranteed.
[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 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.
