Installation instructions for the type Vector
manual group-operated air switch are

1. Drill two mounting holes 11/16" in
diameter located per the user's
construction standards and spaced per
Siemens assembly drawing.
2. Install the mounting bolts in the holes.
Mounting bolts to be furnished by
others.
3. Using the single-point lift bracket, lift
the air switch approximately 4' (1.2 m)
off of the ground (Refer to Figure 3:
Single-point lift bracket)
Note: Be careful when handling the air
switch not to damage the interrupters or
current-carrying parts.
4. Cut the hinge ties on each phase of the
air switch.
5. If surge arresters (supplied by others)
are required, some users prefer to
mount and make-up the surge arresters
at this step.
It is the user's responsibility to adjust
arrester brackets, arresters, ground lead
wires and hot lead wires to provide proper
phase-to-ground and phase-to-phase
clearance.

6. Extension links (supplied by others)
(refer to Figure 4: Extension link) are
required on the jaw side of the air
switch only, if dead ending on the air
switch unit. Some users prefer to install
the extension links at this step.
7. Lift the air switch unit and mount it on
the pole, over the previously installed
mounting bolts and tighten bolts.
Keyhole slots for this purpose have
been machined in the mounting
channel. Remove blade ties from all
three jaw assemblies so that the air
