7. Mount pipe guides and lock segment assemblies in position per customer's construction
standard or Siemens P-O-P Vector assembly drawing using one thru bolt and one lag bolt
each. Tighten the thru bolt and lag bolt until the split washer is flattened.
NOTE: The pipe guides and lock segment are adjustable. Loosen the bolts such that
the pipe guides and lock segment can slide in the slots.
8. Install vertical operating shaft sections and universal joint as shown on Siemens P-O-P
Vector assembly drawing using pins, cotter keys, coupling assemblies (if required) and
insulator assembly (if required). Before placing bottom shaft section in the lock segment,
place the operating handle assembly loosely in position.
NOTE: Make sure that the piercing set screws are backed out all the way
before sliding the handle assembly on the bottom shaft section.
9. Excess pipe should be removed (if required). Leave at least one (1) foot of pipe
extending below the lock segment assembly.
C. Operational check-out instructions:
The next series of steps concern adjusting the position of the handle assembly and lock
segment assembly so that the handle can be inserted into the open and closed slot correctly.
***IMPORTANT NOTE***
It is extremely IMPORTANT to adjust the handle position so that it is IMPOSSIBLE to place the
operating handle in the closed slot unless the switch blades are fully closed. At night and/or
under severe weather conditions an operator may not be able to check the blades visually to
insure that the switch is fully closed.
