1.2.1 Transformer Module Overview
AC Output Circuit Protection: XM2-300HP power supplies use an 8A circuit
breaker. To provide increased durability, an integrated sheet metal guard protects the
line cord and circuit breaker.
LRI (Local/Remote Indicator) : The LRI lamp option is used in conjunction with
the automatic performance feature and plugs directly into the LRI connector. The
LRI circuit is rated at 12Vdc, 250mA. This option duplicates the function of the red
ALARM LED by illuminating an externally mounted red lamp for standby operation.
Output 1 (White = Neutral, Black = Line) : The AC output connector is clearly
marked for easy identification. The service power inserter (SPI) connects directly into
the Output 1 connector.
Output 2 (Optional) [White = Neutral, Black = Line] : The AC output connector is
clearly marked for easy identification. The SPI, which couples power to the load,
connects directly into the Output 2 connector. This feature is part of the
factory-installed PIM option.
