The isolation unit for GP-2500 series (CA2-ISOALL232-01, CA2-ISOALL422-01)

(CA3-ISO232-01) instead. In this case, select “VCC” from [System Settings] ->
[Device/PLC] in the [Project] menu on GP-Pro EX.
2.7 Power Supply
2.7.1 AC Power Supply Type
GP-4501TW has a DC power supply type only. When replacing GP-2500T or
GP-2501T/S (AC Type) with GP-4501TW, changing to DC power supply is required.
If you use the AC power supply, you can replace GP-2500 series with GP-4501T.

replaceable primary ones. (For both a rechargeable type and a replaceable one, contents
to be backed up are the same.)

you to replace the battery, “RAAA053: Running out of power in the backup battery.
Please change the battery.” appears. When the message appears, replace the battery
referring to the GP4000 series hardware manual.
