Straightforward access for servicing.

Use the dedicated battery compartment
Follow the host and battery manuals to open the compartment with the supplied key, fit the pack and secure the cover. The standard installation procedure recommends turning off the host and disconnecting its external supply.
For a supported hot-swap maintenance procedure, follow the exact host manual and keep its alternate power source available. Do not assume every replacement can be made without isolating power.
Check backup power before handover.
Verify charging and the intended standby period
Restore external power and confirm battery status in the Ajax app. Test the power-loss arrangement and alarm path, and document the selected 16h or 60h pack for future replacement.
