Answer

 

 

Turn the UPS on?

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.

 

 

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 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.
