The ADX-H-PSU can be connected to an ADRF-BBU (ADRF Battery Backup Unit) which can provide power
during a power outage. If an ADRF-BBU is utilized, connect the ADRF-BBU to the ADX-H-PSU via the external
battery backup port as shown in Figure 3-20.
(WARNING: The circuit switch on the ADRF-BBU must be set to the OFF position before connecting the ADRF-
BBU to the ADX-H-PSU to prevent damage to the ADX-H-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.
The Battery Install port is used to let ADX-H-NMS know if an ADRF-BBU is connected to the ADX-H-PSU or not.
If an ADRF-BBU is connected without the cable connection to Battery Install port, the ADX-H-NMS will not detect
the ADRF-BBU.
