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.
