Direction of Motor Rotation
To change the direction of motor rotation, cross-connect two of the
output conductors on the SED2 (Figure 25). This is the desired method
for changing rotation.
NOTE: The Reverse Output Phase Sequence parameter (P1820)
can also reverse the direction of rotation. However, if the
SED2 is reset to factory defaults, P1820 is reset to OFF.
