Logic Board is field replaced, field calibration is neces-
sary. Logic Board Program Jumper JP5 (300V/600V)
must be placed in the appropriate position per the com-
pressor motor AC power line.
Logic Board Program Jumper
Place Jumper J5 (300V/600V) in appropriate position
per the Compressor Motor AC Power Line application
as follows:
600V - Place over pins 1 and 2 for 380/400/415,
