To open the ISM15_Shell manually, the torque shall be applied to the interlocking shaft - see Figure 85. The
torque shall be applied counterclockwise of shaft rotation (90 degrees angle). The torque shall not be applied at
the end of shaft rotation. ISM15_Shell_2 has a built in electrical interlock that interrupts the ISM coil circuit after
the interlocking shaft is rotated counterclockwise. After manual trip, the shaft should be rotated clockwise to
unlock the ISM.
