1.2.2 Inverter Module Overview, continued
Battery Switch: The battery switch disconnects the battery from the inverter
module’s DC circuit. With the battery switch turned off, the XM2-300HP power supply
does not transfer to standby mode, the inverter is disabled, and the battery charger
cannot charge the battery.
Battery Input Connector The battery plugs directly into the inverter module’s battery
connector. The connector is polarized and fits in one direction only.
Temp Probe Connector: The Dual Remote Temperature Sensor (DRTS) plugs di-
rectly into the temperature probe (RJ-11C type) connector. One sensor clips onto the
front edge of the power supply shelf and monitors the ambient air temperature within
the enclosure. The second sensor attaches to the negative terminal of the battery
and monitors battery temperature. To install, connect the ring terminal onto the nega-
tive battery terminal as shown below.

Always verify proper polarity of cables before connecting the battery to the power module. Polarity is clearly
marked for easy identification. Reversing the polarity prevents the battery from being active in the system.
