For interrupters with the remote gas-density monitor
option, see “Installing the Transmitter” on page 18. 

For Circuit-Switchers rated 69 kV through 138 kV:

Insert the connecting pin retained from Step 28 into the
coupling and operating rod link. See Figure 13 (left). 

It

will be necessary to loosen the

ing pin can be inserted. Do not remove the screw at this
time.

 Now insert the pin retaining clip retained from Step

28 as indicated in Figure 13 (left). 

Make sure that the clip

is positioned as shown.

 Finally, remove and discard the

 Use a screwdriver blade in the slot at the end of the

connecting pin to align the cross-hole in the connecting
pin with the cross-hole in the operating rod link. Now
insert the pin retaining clip retained from Step 28 as indi-
cated in Figure 13 (right). 

Make sure that the clip is posi-

tioned as shown.
