  • Page 3 ATTENTION: Southern States will begin supplying a portion of new operating mechanism designs with Rapid-Set clevises for orders designed after 9/1/23. If your Operating Mechanism print calls for Rapid-Set clevises (see image below for an example), please utilize the instructions on the following pages for all linkage adjustments.
  • Page 4 Please scan or use the link below for video instructions of Rapid-Set. Southern States Rapid Set Instructions S T E P 1 : Install the auxiliary arm by aligning the straight edge of the arm with the center of the vertical pipe and bolting it into place using two of the provided mounting holes.
  • Page 5 S T E P 2 : Install the adjustable arm with the radius “R” set to the recommended length provided in the operating mechanism drawings. S T E P 3 : Install the auxiliary arm Rapid-Set clevis and drive pipe. Ensure that roughly 12” of pipe extends beyond the adjustable arm clevis connection so that the pipe makes contact with the adjustable arm in the position shown.
  • Page 6 S T E P 4 : With the auxiliary arm properly aligned with the vertical pipe and the switch phase in the full closed position, pierce the pipe at both ends. NOTE: U-bolt style clevises require pre-drilling on all pipes thicker than SCH40.
  • Page 7 S T E P 6 : After the drive phase is adjusted to operate correctly, set all phases to full closed, and install the interphase pipe following the procedure below. For switches driven by the center phase: a. With the interphase pipe centered and all clevises in place, pierce the interphase pipe at the locations shown.
  • Page 8 For switches driven by one of the end phases: a. With the interphase pipe centered and all clevises in place, pierce the interphase pipe with at the locations shown. Do not remove plastic caps at this time. b. Adjust the timing of the center phase by adjusting the length “L” of the Rapid-Set clevis attached to the drive phase.
  • Page 9 c. Set the timing of the last phase by adjusting the length “L” of the Rapid-Set clevis attached to the last phase. S T E P 7 : With all the phases adjusted, open and close the three phase assembly and inspect for proper operation. Once adjustments are finalized, pierce all remaining connections (switch operator, adjustable arm, etc).

    Page 7 of 17 Installation & Adjustment Procedures 1.6.1. After properly installing the rotating insulator, mount the stationary hinge end insulator. Confirm that it is parallel to rotating insulator and shim as necessary. 1.6.2. Once the hinge insulators are aligned, do not readjust them. Any contact alignment adjustments will be made to the jaw insulator.
  • Page 23 Page 8 of 17 Installation & Adjustment Procedures 2.1.2. All contact fingers must be in contact with the blade tip as shown in Figure 4. If necessary, loosen the jaw mounting bolts and rotate the jaw against the bolt hole tolerances to achieve even contact distribution along the length of the blade tip.

    Operating Mechanism drawing. See Table 1 for torque spec. 4.6. Conventional blade open positions are shown in Figure 9. The EV-H switch will be shipped with one of these blade open angles unless another angle is specified. Slight changes to the blade fully open angles can be made in the field. Adjust the open position stop bolt on the bearing assembly shown in Figure 10 as necessary.
