1.3.5 Inverter Module Overview
The removable Inverter Module provides uninterrupted power to the ferroresonant transformer (via the batteries) during
utility failures. During normal operation, the inverter charges the batteries using a three-, four- or five-stage (Bulk, Accept,
Refresh, Rest and Float) charging protocol determined by the charger setting and battery type.
Smart Display: All operational functions, system testing, programmable items and alarms are available via the
Smart Display panel on the front of the power supply.
Softkeys: Provide access to the various menus and submenus within the Alpha XM3-HP.
Output LED: Indicates output state of the Alpha XM3-HP.
Alarm LED: Indicates Alarm condition.
Self Test button: Initiates Self Test.
Local/Remote Indicator Connector: Indicates alarm condition to exterior lamp.
The Precision Temperature Sensor (PTS): Plugs directly into the Temperature Probe (RJ-11C type) Connector.
Battery Circuit Breaker: Controls battery DC power to the inverter.
Battery Cable Input Connector: The battery cable connector plugs directly into the Inverter Module’s battery input
connector. The connector is polarized and fits in one direction only.
