Installation instructions for the type Vector
manual group-operated air switch are
detailed in the following steps:
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.
