S&C Series 2000 Circuit-Switchers
Interrupter Replacement
Outdoor Transmission (69 kV through 230 kV)
Installing the Transmitter
When replacing an interrupter on Series 2000 Circuit-
Switchers with the remote gas-density monitor option, the
transmitter must also be replaced. Following are the
replacement and setup instructions for the remote gas-
density monitor transmitter. For installation and operat-
ing instructions for remote gas-density monitors in new
Circuit-Switcher installations, refer to Instruction Sheet
716-530, “S&C Series 2000 Circuit-Switchers: Remote Gas-
Density Monitor.”
Step 37
Before mounting the replacement interrupter to its associ-
ated transition box, locate the red sensor cable on the
base of the interrupter. Cut and remove the wire ties and
the wire tie mounts securing the sensor cable, taking care
not to damage the cable. Do not remove the shorting plug
from the end of the green 6-pin connector at this time. See
Figure 14.
Step 38
On Circuit-Switchers with vertical interrupters (Model
2020, Model 2025, and Model 2030), the transmitter is
mounted in place of the transition box access cover.
Remove the four

socket-head cap screws
and flat washers that secure the transmitter to the transi-
tion box. Reserve the mounting hardware and set the
replaced transmitter aside in a protected area. See
Figure 15.

CAUTION
Exercise care
when mounting the interrupter to the
transition box. The sensor cable is factory-installed on
the interrupter and cannot be replaced in the field if
damaged.
Damage to the cable will necessitate
returning the interrupter and transmitter to the
factory for replacement and recalibration.
