BEFORE STARTING INSTALLATION
Checking the Shipment
An S&C catalog drawing will be found in a water-resistant
envelope attached to the plastic bubble-wrap around one
of the insulating support columns. Study this drawing
carefully and check the bill of material to verify that all
parts are at hand.
The Model 2010 Series 2000 Circuit-Switcher shipment
should include the following items, as shown in Figures 2
and 5:
1. Three pole-units, each consisting of an interrupter,
integral disconnect blade, insulating support column,
support insulator, and channel base—all factory-
assembled and adjusted.
2. A single cross base, enclosing the high-speed inter-
phase power train which drives the interrupters.
3. The appropriate number of mounting pedestals, com-
plete with support arms and channels. A single pedes-
tal is used for Circuit-Switchers rated 69 kV (with 48-
inch phase spacing); a set of two pedestals is used for
Circuit-Switchers rated 69 kV (with 84-inch phase spac-
ing), 115 kV, and 138 kV; and a set of three pedestals is
used for Circuit-Switchers rated 161 kV and 230 kV.
4. A Series 2000 Circuit-Switcher Operator.
5. A low-speed interphase power train which drives the
disconnect blades.
6. A container of miscellaneous operating-mechanism
components and hardware—all individually identified.
7. Any optional features specified, such as a grounding
switch.
Gas-Pressure Indicator
Series 2000 Circuit-Switchers have sealed interrupters
containing gas under pressure. Low gas pressure is sig-
naled by a red target in the gas-pressure indicator at the
terminal end of the interrupter.
DO NOT INTERMIX COMPONENTS FROM
DIFFERENT INSTALLATIONS
Series 2000 Circuit-Switchers are completely fac-
tory-assembled and thoroughly tested. To speed
installation and maintain proper adjustment of the
Circuit-Switcher and its operator, it is imperative
that components belonging to a specific Circuit-
Switcher installation not be intermixed with compo-
nents belonging to a different installation. For this
reason, each Series 2000 Circuit-Switcher is serially
numbered. This serial number appears on the indi-
vidual pole-units, the cross base, the mounting ped-
estals, and the operator.
It is further important that components from dif-
ferent installations not be intermixed in that S&C
maintains an historical record—by serial num-
ber—of every Circuit-Switcher produced. This
record lists information pertinent to each installa-
tion, such as application, date of shipment, and any
service performed by S&C field service specialists.
This record is invaluable when questions arise rela-
tive to modifications or replacements.
Please complete and mail the Circuit-Switcher
registration card (enclosed in a vinyl envelope
located inside the operator) after the Circuit-
Switcher has been installed. The information
requested on this card is vital to ensure prompt
notification in the event field modifications are
needed.
Storage
If the Circuit-Switcher must be stored before installation,
keep it in a clean, dry, corrosion-free area to protect it
from damage. If storing outside or in a non-climate con-
trolled area, connect control power to the space heater
inside the Circuit-Switcher Operator per wiring diagram.
Inspect the Circuit-Switcher regularly when stored for
prolonged periods.
NOTICE
The Series 2000 Circuit-Switcher Operator is equipped
with a space heater that must be energized during
storage to prevent condensation and corrosion within
the operator enclosure.
NOTICE
Loss of gas pressure may result in improper interrupt-
ing action. The red target should not be visible. If the
red target is visible, stop the installation and notify
S&C Electric Company.
