When the Battery S/W is set to the ON position, the power supply charges the optional ADRF-BBU (External
Backup Battery) (Figure 3-35).
The RU PSU can be connected to an ADRF-BBU (ADRF Battery Backup Unit) to provide power during a power
failure. If an ADRF-BBU is utilized, connect the ADRF-BBU to the RU PSU via the external battery backup port as
shown in Figure 3-35.
(WARNING: The circuit switch on the ADRF-BBU must be set to OFF before connecting the ADRF-BBU to the
HE PSU to prevent damage to the HE PSU or the ADRF-BBU and personal injury.)
Note: Please contact ADRF Technical Support for assistance if you are unfamiliar with the installation
procedure of our battery box.
