1.2.2 Inverter Module Overview
The removable inverter module provides uninterrupted power to the transformer
(via the batteries) during line failures. During line operation, the inverter charges the
battery using a three-stage (BULK, ACCEPT, and FLOAT) charger.
Smart Display: All operational functions, system testing, setup items, and alarms
are available via the Smart Display panel on the front of the XM2-300HP (the
Smart Display is covered in detail in Section 4.2). Display functions are accessible
by pressing any of the four keys: ESCAPE, UP, DOWN or ENTER. Backlighting
is activated when any of the four keys are pressed, and stays lit for a period of
one hour. There are four levels of menu items: Operation Normal, Communication
Information, Setup and Alarms. Pressing ENTER will sequence the display one level
lower, and pressing ESCAPE will sequence the display one level higher.
