IMPORTANT NOTE: In order for the USM2 to function correctly, OUTPUT (N) must be grounded to the XM2
Series 2’s chassis! During normal operation this is automatically done though the SPI, but during bench
testing this ground will have to be manually maintained, by placing a jumper between the Output Neutral
and chassis ground.
