The marked input voltage of –48 VDC for a DC-powered device is the nominal voltage
associated with the battery circuit, and any higher voltages are only to be associated
with float voltages for the charging function.
Because the device is a positive ground system, you must connect the positive lead to
the terminal labeled , the negative lead to the terminal labeled –48 VDC, and the
RTN
earth ground to the device grounding points.
