13.4 Power Supply Wiring
DC power supply wiring
• Connect the DC power supply to the [+] and [-] terminals.
• 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.
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
*1
, CPU module, and safety extension module.
When the above condition is not satisfied, an error (error code: 3052H) may occur in the safety extension
module.
For details on wiring, refer to the following.
MELSEC iQ-F FX5 User's Manual (Safety Control)
*1 The "modules other than the safety extension module/CPU module" are as follows.
