FORMULA
C. For phase 3 control card measure AC input at Line 1 to Line 3.
Example:
FORMULA
Actual AC Input x 2.47
480 (Nominal)
475 Volts AC Input x 2.47

After calculations are complete, place DC voltmeter on the 20 volt scale and check between TP2 and TP
GND on control card. Adjust pot P1 so meter reads DC level calculated in Step 7 for all three phases.

NOTE: Be sure to turn power off when replacing circuit boards.
NOTE: If adjustments in Steps 6 and 7 are not possible, replace control card #414921 and
repeat Steps 6 and 8.
NOTE: Be sure AC input is stable when making this adjustment. If the input changes, you must
re-calculate.

Turn the unit off. Plug in TB2 Molex connectors to all the control cards #414921.
NOTE: Output voltage correction is a "stepped correction", adjusting P1 will not cause a
smooth change in output voltage as it is adjusted.
