What are the battery requirements for a fully loaded NFS2-3030, and how do I size the batteries?

The NFS2-3030 requires two 12-volt batteries with a capacity between 7 AH and 200 AH, which are charged by the mandatory AMPS-24(E) power supply (Page 5, 8) [1].

To size the batteries, you must use the current draw calculation sheet found in the AMPS-24(E) Manual 51907 (Page 8) [1].

This calculation must include the standby and alarm current for all system components, such as the CPU2-3030D board (0.340 A standby), each LCM-320 loop module (0.130 A), and each LEM-320 expander (0.100 A) (Page 8) [1].

Batteries exceeding 26 AH require a separate enclosure, such as the NFS-LBB for up to 55 AH, the BB-100 for up to 100 AH, or the BB-200 for up to 200 AH (Page 6, 7, 8) [1].
