3.4 Power Supply
Figure 6 illustrates wiring between the PM-10 power management board and the
AC-225x-B. Make sure the connection polarity is correct, (+) to (+) and (-) to (-).
Connect the power to the input power terminals of the control panel. It is
recommended to add a 12 VDC lead acid backup battery (requires the ME-1015
Power Management Enclosure) to have uninterrupted operation in case main
power supply fails. A 12 V, 7 AH battery provides 3 hours of backup operation.
