Calculating Current Draw and Standby Battery

This section helps you determine the current draw and standby battery needs for your installation (18
Ampere Hours max. will fit in cabinet). Complete the remaining instructions in Table 4-3.
Batteries larger than 18 AH will not fit in the main control cabinet, and must be housed in the RBB
Accessory Battery Cabinet. Maximum of 33 Amp Hours per system.
