3.4.1 CONFIGURE TRANSFORMER RATIO
NOTE:
Most users will not need to concern themselves with the unit configuration as it is set at the
factory if the UPC is packaged with a power source.
Set the TRANSFORMER RATIO of the UPC to be the same as the turns ratio of the Output XFMR in the
Power Source. Refer to the Power Source Manual to determine the TRANSFORMER RATIO of the
Power Source. The ratio is set by the TRANSFORMER RATIO SWITCH on the UPC METERING PCB.
See figure 3.4.1. The Dip-switches S2-8 and S1-1 thru S1-8 are binary weighted:

NOTE:
TRANSFORMER RATIOs are implied as a ratio to one, e.g., a setting of 2.5 is implied as a ratio
of 2.5:1.
