Questions about this item

How do I install the RBC24 cartridge into my SU1400RMI2U UPS?

Power down the UPS, open the front battery door, disconnect the old cartridge connector, slide the new cartridge in until it clicks, reconnect the plug, close the door, then run the self-test to confirm the replacement is recognised.

When should I replace these 12 V lead-acid cartridges?

Plan replacement after three to five years of service or sooner if the UPS reports a battery fault, runtime falls noticeably, or the self-test fails.
