Answer
Verify that all power modules are securely plugged into the cabinet, and each
module handle is latched. Also confirm that the DC disconnect button on the
back of the external battery cabinet is closed (pulled out). Turn the optional
external bypass 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.
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 bezels, 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, press the large, red DC
disconnect button on the back of the battery cabinet nearest to the UPS cabinet.
Press the lower left button on the front panel display. Note the alarm message
and see "Alarms" on page 83 to correct the problem. After the problem has
been resolved, press the lower center button to clear the alarm.
