CHECK VOLTAGE IMBALANCE
IS CONDENSER MOTOR WIRED FOR CORRECT VOLTAGE? (Y/N)
LINE-TO-LINE VOLTS: AB VACVBCV
(AB + AC + BC)/3 = AVERAGE VOLTAGE =
V
MAXIMUM DEVIATION FROM AVERAGE VOLTAGE =
V
VOLTAGE IMBALANCE = 100 X (MAX DEVIATION)/(AVERAGE VOLTAGE) =
%
IF OVER 2% VOLTAGE IMBALANCE, DO NOT ATTEMPT TO START SYSTEM!
CALL LOCAL POWER COMPANY FOR ASSISTANCE.
