change nameplates on pushbutton assembly. The upper/lower safety limit switch is
wired in series with “UP” control circuit as furnished from factory. Changing
pushbutton control leads or nameplates will prevent the upper safety travel limit switch
from functioning properly.
Reversing any two power leads of a three-phase AC motor will reverse the direction of rotation.
Reverse any two leads of a three-phase power at the main power source or at connections to motor.
Do not change internal wiring of hoist.
After changing two of the main power leads, recheck direction of rotation. Press “
