Compaq 2000 - Manual (Page 50)

Configuration 4-7
NOTE: For nominal voltage configuration parameters 1, 2, 3, and 10—selecting an ON
value for any one parameter automatically sets the other three possibilities to OFF.
5. To scroll through the configuration parameters, press the ON button
(
2). The UPS acknowledges compliance with a short beep. Monitor the
LED display (see Figure 4-2; LED 1 blinks to indicate that parameter 1
is selected, LED 2 blinks when parameter 2 is selected, and so on).
6. Repeat Steps 2 through 5 as required. Continue until all changes have
been made.
7. To exit the Configure mode at any time:
q Press the ON (
2) and TEST/ALARM RESET buttons (4)
simultaneously, or
q after parameter 15 is accessed, press the ON (
2) button.
The UPS will acknowledge compliance with a short beep.
Optimizing Battery Life
by Matching the Utility Voltage
Optimize UPS battery life by using the configuration parameters to select the
best nominal voltage range for the UPS installation.
When utility voltage is outside the selected operating range, the UPS supplies
battery power to the output receptacles. Maximize the UPS battery life by
configuring the UPS so that the utility voltage is normally within the selected
operating range.
