.3 Expansion Unit (for GP-3500S/L only)
GP-4501T/TW is not equipped with an expansion unit interface. The expansion unit
(each kind of unit like CC-LINK Unit) for GP3000 series cannot be used.
.4 Isolation Unit (for GP-3500S/L only)
RS-485 isolation unit for GP-3500 series (CA3-ISO485-01) cannot be used for
GP-4501T/TW. You can use the RS-232C isolation unit (CA3-ISO232-01) for
GP-4501T/TW instead.
2.8 Power Connector
The power connector on GP-4501T (AC type) has the same terminal block as
GP/ST-3500 series, but the FG location is different.
GP-4501TW has a DC power supply type only. When replacing GP/ST-3500 series (AC
type) with GP-4501TW, changing to DC power supply is required.
2.9 Backup Battery
Unlike GP/ST-3500 series, GP-4501T/TW does not use rechargeable secondary
batteries but replaceable primary ones. (For both a rechargeable type and a
replaceable one, contents to be backed up are the same.)
When the time for replacement of backup batteries approaches, the message to urge
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.
