*1 Connect the AC power supply to the [L] and [N] terminals (common for 100 V AC system and 200 V AC system).
Make sure that the powered input/output module is turned on at the same time as the CPU module or earlier than the CPU module.
*2 Connect the [24V] terminal of the CPU module to the [S/S] terminal of the input module.
*3 Some expansion adapters and intelligent function modules may not have power supply terminals.
When using an external power supply, turn on the power supply at the same time as the CPU module or earlier than the CPU module.
When turning off the power, confirm the safety of the system and turn off the power of the PLC (including extension devices) at the same
time.
*4 Do not connect the [24V] terminals (24 V DC service power supply) of the CPU module and the powered input/output module with each
other. Connect the [0V] terminal.
