Installation: 1.Disconnect Power2.Connect terminals in series with the device3.Reapply power and check operation. for complete diagrams,
see installation guide Mode of Operation: Upon application of power of the three phase line and control voltage, the three phase lines are interrogated for proper phase sequence, symmetry and amplitude. Upon
verification, thecontrol coil circuitry is energized and the line integrity once again verified on the load (back) side of the contactor.
Shouldno faults occur, the system will maintain its ON state.
