Procedure to confirm the battery count
1. Apply AC input power to the UPS.
2. Turn the UPS output off using the Standby button. If the UPS is in inverter mode, the
load must first be transferred to bypass and then to off.
3. Once the UPS output is off, press and hold the Standby button continuously. The Standby
button must be held continuously for the duration of this procedure. The UPS will do
nothing for the first 10 seconds. After approximately 10 seconds, the LED display will
scroll and the horn will beep. When the LED display comes to rest (about 15 seconds after
first pressing the Standby button), the battery cabinet count will be displayed on the Load
LEDs. The count will display as long as the Standby button is continuously held.
4. If the Standby button is released at any time, the entire procedure must be restarted.
5. Once the battery count is displayed, or at any time if you wish to abort the procedure, you
may release the Standby button and restart the UPS using the ON button.
Procedure to change the battery count
This procedure required the simultaneous use of the Standby button and ON button. No other
UPS procedure calls for simultaneously pressing the Standby and ON buttons.
The first three steps of this procedure repeats Steps 1 through 3 in the Procedure to con-
firm the battery count. However, once the battery count is displayed, you have the option of
changing the count. As before, the Standby button must be held continuously for the entire
procedure. Releasing the button prematurely will require that the whole process be repeated.
1. Apply AC input power to the UPS.
2. Turn the UPS output off using the Standby button. If the UPS is in inverter mode, the
load must first be transferred to bypass and then to off.
3. Once the UPS output is off, press and hold the Standby button continuously. After
approximately 10 seconds, the LED display will scroll and the horn will beep. When the
LED display comes to rest (about 15 seconds after first pressing the Standby button), the
battery cabinet count will be displayed on the Load LEDs. The count will display as long
as the Standby button is continuously held.
4. If the displayed battery count is incorrect, press the ON button for 1 second while
simultaneously continuing to hold the Standby button. The display will scroll and the
horn will beep, and the battery count will be increased by one.
5. If the desired battery count has not been reached, repeat Step 4. The count can only be
increased. After a count of 5 is reached, the count will restart at 1.
6. Once the desired battery count is displayed—or at any time you wish to abort the
procedure—you may release the Standby button and restart the UPS using the ON
button.
