INSTALLATION
Installing the Mark VI CS-1A
Switch Operator and Vertical Shaft
Mount the switch operator to the user-furnished
structure as indicated on the erection drawing.
The structure supporting the switch must meet
the construction guidelines listed in S&C Data

NOTICE
If more than one Mark VI CS-1A Switch
Operator is available at the installation
location, take care to select the one for this
particular installation.
Step 26
Unbolt the Mark VI CS-1A Switch Operator from
its shipping skid.
Step 27
Attach lifting slings around the output shaft
of the Mark VI CS-1A Switch Operator. See
Figure 24. Lift the operator into place on the
user-furnished mounting structure. Avoid
sudden starts and stops.
Step 28
Align the upper and lower fl anges on the rear of
the operator with the user-furnished mounting
surface provided on the structure. Fasten the
operator to the structure using the ⁵⁄₈-inch
holes provided on the mounting fl anges, as

slings from the operator until the operator is
fully supported—using both fl anges—by the
