IMPORTANT NOTE:
The charger controller is a component on the RMC electronic board that
controls the battery charging process. The charger controller's design optimally controls the charge
and hold cycle for the battery. It prevents overcharging or complete draining of a battery. It
supports
the three charge states: high current bulk charge, controlled over-charge, and a float
charge.
Figure 2-11: Battery mode with solar charger
Figure 2-12
illustrates the external power mode connection where an external power source supplies
the power to the RMC at the CHARGER/EXT PWR port. In this configuration, the external power supply
is the sole source of power to the controller.

IMPORTANT NOTE:
If you do not use ABB-approved power sources, verify that customer-
supplied power sources meet these requirements. For additional details about requirements, see
section
3.1 Site planning and requirements.
