Question: “How do I ... ” Answer
Turn the UPS on? Verify that all power modules are securely plugged into the cabinet, and each
module handle is latched.
If external battery cabinets are installed, confirm that the DC disconnect switch
button on the back of the cabinet is closed (pulled out). To close the DC
disconnect switch button, insert the switch key supplied with the cabinet into
the button and turn clockwise 1/2-turn. Pull the button out to close the switch.
Turn the key back counter-clockwise, and remove the key.
If an external bypass switch is installed, turn the switch to the LINE or UPS
position.
Refer to the front panel display and press the button labeled ON. (If On/Off
control is password-protected, enter the user password: 0377.) Confirm the
selection by pressing the button labeled Yes. After a few seconds, the green
LED illuminates to signal the UPS is operating and producing power.
Turn the UPS off? Refer to the front panel display and press the button labeled OFF. Confirm the
selection by pressing the button labeled Yes. (If On/Off control is
password-protected, enter the user password: 0377.)
In the event of a front panel display failure, you can turn the unit on or off
using a computer connected to the communication port.
In an emergency or when the above two methods fail to turn the unit off,
remove the front cover panels, and unlatch and pull the handles of all power
modules out at least one inch (2.5 cm) to turn off the power control circuitry.
If your UPS has external battery cabinets, push in the DC disconnect switch
button on the back of the battery cabinet nearest to the UPS cabinet.
Turn off the alarm beeps? Press the lower left button on the front panel display. Note the alarm message
and see “Alarms” on page 105 to correct the problem. After the problem has
been resolved, press the lower center button to clear the alarm.
View the alarm log? Go to menu 2-2. Press the button to view the most recent alarm. Press the
