The following paragraphs describe the various status and informational screens that

are available with the CDN-UPS1250. These are accessed by using the STATUS

button on the front panel.

NOTE: For your convenience, you can set the unit to display any of the status

screens as the “default” screen. The default screen is the screen that the system will

return to once the preset time has expired for other screens that are being displayed.

NOTE: The display will revert to the default screen after about 30 seconds of

inactivity. To change the default screen, first press the STATUS button until the

desired screen is displayed. Then press and hold the STATUS button for

approximately three seconds until the screen displays CURRENT SCREEN IS

SAVED AS DEFAULT.

The “SOURCE: XXXXXXX; EST. RUNTIME: XHRS” screen displays which type

of source the unit is deriving power from (UTILITY, BATTERY or STANDBY). It

also displays the EST. RUNTIME based on the power source and connected

equipment load. In STANDBY, the unit does not provide power to the rear panel

outlets.

NOTE: When the CEN-UPS1250 is connected to utility power, the electronics

inside the unit are active. If the front panel power switch is turned off, the unit goes

into STANDBY mode and shuts off power to the rear panel outlets but the display

remains active.
