Installation
Before Starting
The Type CS-1A Switch Operator is a high-speed operator
expressly designed for power operation of the MarkVCircuit-
Switcher. Use Table 1 to identify the associated wiring
diagram that should be consulted for the model of switch
operator being installed. Check the catalog number on the
switch operator to see that it is the correct operator for
the installation before starting the installation. Become
familiar with the parts of the switch operator as shown in
Figures 2 and 3 on pages 8 and 9 and Figure 4 on page 10.

① Based on minimum battery and external control wire size require-
ments specified in S&C Data Bulletin 719-60; operating time will be less
if a larger than minimum battery size and/or external control wire size is
used�
● Catalog number 38858R1-B is used for applications where the cir-
cuit-switcher is to be used in conjunction with an S&C Automatic Control
Device unless the switch operator is ordered with the optional shunt-
trip contactor and time-delay relay accessory, catalog number suffix
“-HP�” In this instance, catalog number 38846R5-BHP will be specified�
CDR-3183 is used for catalog number 38846R5-BHP� CDR-3195 is
used for catalog number 38858R1-B�
WARNING
Unauthorized changes should not be made to the wiring
of the Type CS-1A Switch Operator� Should a control-
circuit revision appear desirable, it should be made
ONLY on the authority of a revised wiring diagram that
has been approved by both the user and S&C Electric
Company� Unauthorized changes may make the function
of the operator unpredictable, causing damage to the
operator, associated Mark V Circuit-Switcher, and
possible serious personal injury�
