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 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.
