Determine the nominal AC line voltage for the system. This is the value from the list
(200, 208, 220, 230, 240) that is closest to the average just computed.
For example, using the data in
Source A Voltage = 249
Source B Voltage = 240
Average AC Line voltage = (249 + 240) / 2 = 244.5
Nominal AC line voltage = 240 because that is the closest number to 244.5 from the list.
Note: Use this value when setting the BBUs’ nominal voltage (as described later in
