Page 8: Installation
Installation Mounting to Wood NOTICE When mounting to a wood structure, a spring-type washer must be used between the square washer and the nut to maintain fastener tightness in the event of wood shrinkage . See Figure 2 . Preparing the Pole STEP 1.
Page 9: Uncrating The Switch
Installation Uncrating the Switch Remove the switch from its crate. See Figure 5. STEP 3. Protect the bearings from contami nation by dirt, mud, oil, etc. If necessary, use blocks to keep the bearings clear of the ground. For tiered-outboard mounting configura tion switches proceed to Step 4 below.
Page 10 Installation STEP 6. Guide the switch so the through-bolt heads enter into the keyhole slot and open slotted hole in the switch base. See Figure 8. STEP 7. Slowly lower the switch until it just bears on the through-bolts. Fully tighten the bolts. See Figure 9.
Page 11: Lifting Vertical Mounting Configuration Switch
Installation Lifting Vertical Mounting Configuration Switch To minimize time-consuming fi nal adjust ments, STEP 9. make sure the switch is fully closed. Tie the switch blades to their station ary main contact assemblies. See Figure 11. STEP 10. WARNING DO NOT lift the switch by rigging to the live parts .
Page 12 Installation STEP 11. Guide the switch so the through-bolt heads enter into the keyhole slot and open slotted hole in the switch base. See Figure 13. STEP 12. Slowly lower the switch until it just bears on the through-bolts. Fully tighten the bolts. See Figure 14.

Installation STEP 13. Attach the pole bands to the switch base anchor brackets using the J-bolts furnished. Use a stiffening block under each nut. See Figure 15. Use a ⅝-inch diameter lag bolt (not fur nished) to secure each pole band to the utility pole. Installing Pipe Couplings with Piercing Set Screws WARNING...
Page 14: Installing Vertical Operating Pipe
Installation Installing Vertical Operating Pipe STEP 14. One of the pipe sections furnished is threaded at one end to accommodate the operating handle assembly. See Figure 17. Install this section of pipe last, with the threads at the lower end. If only one vertical operating-pipe section is required, proceed to Step 17.
Page 15: Installing Operating Handle
Installation Installing Operating Handle ● STEP 17. Mount the operating handle assembly as shown on the erection drawing. At the same time, use one of the mounting bolts to attach one end of the ground strap (the end with the grounding connector attached) to the handle mounting plate.
Page 16 Installation STEP 19. Insert the upper end of this pipe section in the lowest rod guide or—if only one vertical oper- ating-pipe section is used—the offset cou pling attached to the switch lever. While holding the operating handle at a point approximately 20 degrees from the Closed position, torque the rod guide (or switch lever) coupling clamp bolt.
Page 17: Checking Alignment
Installation Checking Alignment Remove tie Remove the ties holding the switch blades to STEP 21. their stationary main contact assemblies. See Figure 24. Remove the 45-degree positioning stud from each rod guide. See Figure 19 on page 14. Open and close the switch slowly to ensure no operational difficulties are encoun tered due to undetected damage in shipping.
Page 18: Installing Key Interlock
Installation STEP 23. If there is still slack, repeat the procedure in Step 19 but move the operating handle more than 20 degrees in the opening direction before torquing the clamp bolt on the lowest rod guide (or switch drive lever) coupling. See Figure 26. Conversely, if considerable force is needed to move the handle to the fully Closed posi tion, or if the handle does not swing 180 degrees to the...
Page 19: Checking Operation
Installation Block one of the two slots in the locking disc STEP 25. with the blocking screw provided. (The slot to be blocked depends on whether a locked-open or locked-closed arrangement is required.) See Figure 28. NOTICE Key interlocks are intended for proper sequencing of switch operations;...
Page 20 Installation (b) With the operating handle as far as it will go in the opening direction, the switch blades are 90 degrees from the Closed position. See Figure 30. In the unlikely event that the above-described conditions are not met, more switch blade travel is required.
Page 21 Installation STEP 27. Open and close the switch slowly several times. Blade-closing cam WARNING Open and close the switch slowly ONLY when checking operation or making adjust- ments to the de-energized switch . When opening or closing an energized switch, swing the operating handle vig- orously through its full travel without hesitation .
Page 22 Installation (c) Also, when the blade is in the fully Closed position, each blade-closing cam must overlap its respective interrupter closing lever to pre vent inadvertent opening of the interrupter, and clearance between the blade-closing cam and its respective interrupter closing lever must be within the limit shown.
Page 23: Connecting High-Voltage Connectors
Installation (g) Move the blade assembly slowly toward the Closed position until the blade assembly is under the interrupter lever shaft. Verify the gap between the end of the interrupter lever shaft and the blade assembly is between and 3∕16-inch (5 mm) and 9�32-inch (7 mm).
Page 24: Operation
Operation Opening and Closing the Switch DANGER The interrupters and terminal pads of the Alduti- Rupter Switch may be energized with the interrupters in any position . Before inspecting, servicing, or repair- ing this switch or working on the conductors on either side of the switch, test for voltage using proper high-voltage test equipment .
