Main Power Supply
Wire size
NOTE: If using an auxiliary power supply such as FCPS-24S6/S8, APS-6R, ACPS-2406, or
ACPS-610, or audio amplifiers, refer to the documentation for that equipment.
Batteries
The control panel uses only sealed lead-acid batteries for secondary standby power. Maximum
battery capacity for the CPS-24/E main power supply is 200 AH. CAB-4 Series backboxes provide
space for two 26 AH (or smaller) batteries. Use external battery boxes if the installation requires
larger capacity batteries; see Table A.5, "Selecting Battery and Battery Backbox," on page 69.
The table below contains battery charger specifications.
