7.2.3 Pushbutton Functions

The pushbuttons allow the user to operate the UPS to perform settings and adjustments, to start-up and shutdown the UPS, and to monitor on the LCD display the voltages, currents, frequencies and other variables of system operation.

KEYS	FUNCTION
ON/OFF	Turn-on UPS system (press both pushbuttons simultaneously)
	or
ON/OFF	Shutdown the UPS (press both pushbuttons simultaneously)
UP ( )	Move upwards through the menu
DOWN ( )	Move downwards through the menu
RESET	Move to the top of the menu. Cancel the audible alarm. If the alarm
	condition was only transient, the LED indicator (ALARM) will also

7.2.4 ON/OFF Startup and Shutdown Pushbuttons

By pressing simultaneously both ON/OFF pushbuttons on the Control Panel, the UPS can be switched on (if currently OFF) or shutdown immediately (if currently ON). Requiring both to be simultaneously depressed prevents accidental operation of the UPS. The two main ON/OFF pushbuttons are also used as a security ON/OFF switch, making it possible to quickly disconnect the load from the UPS in emergency situations. Upon startup from initial install or power off disconnect, the UPS starts in NORMAL (inverter) mode. In subsequent startups, the system will return to the mode previously used before shutdown, except that ECO mode will require operator intervention to activate.
