Power Supply Wiring

AC power supply wiring

• Connect the AC power supply to the [L] and [N] terminals (common for 100VAC system and 200VAC system).
• Note that the power of the powered input/output module is turned on at the same time as the CPU module or earlier than
the CPU module.
• Some expansion adapter 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, check the safety of the system and turn off the power of the programmable
controller (including extension devices) at the same time.
• Do not connect the [24V] terminals (24VDC service power supply) of the CPU module and the powered input/output
module with each other. Connect the [0V] terminal.
• When using an extension power supply module, pull out the power cable and ground wire above the product as shown
below.

When using a safety extension module, power on all the modules at the same time.
If all the modules cannot be powered on simultaneously, power them on in the following order: the modules
other than the safety extension module/CPU module
When the above condition is not satisfied, an error (error code: 3052H) may occur in the safety extension
module.
