CAUTION
To prevent changing motor rotation, the
motor leads should be reordered in the
same direction, see example on page 51.
RULE OF THUMB
If the unbalance moves with the motor
leads the unbalance is caused by the
motor, wet splice, or damaged cable. If
the unbalance remains with the terminals
the unbalance is in the power supply
.
For the best protection, we recommend no more
than a 5% current deviation from average current.
Current readings in amps should be checked on
each leg using the three possible hookups.
