Hot Swapping Battery module in my BN1500M2

[paramedic228]

Just want to verify that I can hot swap the battery module in my BN1500M2. It seems pretty similar to most other units that I have worked with. I just don't find anything specific in the manual or instructions.

S h o r t Answer: No

Long Answer: There are no Back-UPS Series units (designed) to be hot swapped. Hot swap capability is available in the Smart-UPS / Symmetra Series units.

Having stated that you can validate this by disconnecting the RBC while powered by AC Mains.

You may see the following scenarios so pay special attention to how the system reacts.

1. Unit will turn off immediately

2. Unit will remain on but drop the load

3. Unit will remain on and continue to support the connected load.

All of the above is dependent upon the design and firmware in place. At a high level all hot swap capable systems use Anderson connectors or shrouded push in cartridge to provide a measure of human safety and isolation.

A person will never be required to disconnect multiple battery terminals while the system is powered by AC Mains.

Almost every hot swap RBC comes in the form of an enclosed cartridge / sled. Almost every hot swap device the front bezel can be removed and the RBC is accessible via the front once all the screws are removed.

The user is never required to turn a system over to access / replace the RBC.

NOTE: In the past there have been some Back-UPS Systems that behaved as described in option 3.

This was not an intended design choice vs an oversight from the engineers.
