Front Panel Indicators
LEDs
To indicate the status of the UPS and its battery pack, there is one LED above the ON/OFF switch
on the left side of the front panel of the UPS and an additional 16 LEDs on the front panel of
each battery pack, for a total of 32 LEDs. There is also an audible alarm. These indicators are
described in this section.

This LED has four possible indications, according to the table below:

LEDs on the Battery Packs
Each battery pack has 16 LEDs, as shown below, that indicated the status of the battery pack and
of the operation of the UPS. There are two separate units used in parallel to provide the load,
the indicators on the top vs. the bottom reflect the state of the top unit and the bottom unit
respectively. For example, it is conceivable that DCOUT1A and DCOUT1B load currents differ
significantly, resulting in different reflected loads on the front panel, battery state of charge,
temperature, etc.
