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

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 covers, and unlatch and pull the handles of all power modules out at least 2.5 cm (1”) 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.
