Manual Operating Controls
The operating controls for the sectionalizer are located
on the underside of the operator mechanism housing, as
shown in Figure 4.
Manual Opening
The hookstick-operated, manual opening pullring trips
open the sectionalizer with one pull of the yellow pullring.
One-Count-To-Open Lever
The one-count-to-open lever provides the capability of
opening the sectionalizer on the first overcurrent interrup-
tion count. It provides for added safety during downline
hot-line work without disturbing the normal counts-to-
open setting of the sectionalizer. The hookstick-operated
lever locks into position when pulled down, and must be
manually reset to restore normal counts-to-lockout.
Manual Closing
The hookstick-operated, manual closing pullring closes
the sectionalizer when the gray pullring is pulled down
approximately 10 to 12 times. The pullring manually
charges the closing springs and overtoggles the springs
to initiate the closing. (When the sectionalizer closes,
the resistance on the pullring is eliminated.) This is the
only means of closing the sectionalizer.
Auxiliary Power
Auxiliary power (120 Vac, 25 VA, min.) is required for the
cabinet heater and/or potential charging of the trip
capacitor. The input receptacle is located on the underside
of the operator cabinet (Figure 4). A mating connector
plug is also provided with the unit.
Indicating Devices
A contact position indicator and an operations counter
are located under the sleet hood of the operator cabinet.
The yellow contact position indicator is pinned to the
main operating shaft of the sectionalizer to indicate the
OPEN and CLOSED condition of the main contacts.
The operations counter gives a visual indication of the
cumulative number of openings of the unit.

OPERATING CONTROLS AND SETTINGS
IMPORTANT:
The potential charging board also includes
a voltage restraint feature which prevents the unit from
counting overcurrent interruptions unless the auxiliary
voltage is also interrupted. Therefore, the auxiliary power
must be obtained from the load side of the backup
protective device so that the board is energized only
when the backup is closed. Failure to follow this pre-
caution will prevent proper operation of the sectionalizer.
WARNING:
Do not rely on the open position of
the yellow operating handle; it does not ensure
that the line has been de-energized. Always establish
a visible disconnect. Failure to follow proper safety
practices can result in contact with high voltage, which
will cause death or severe personal injury.

WARNING:
Always use a hotstick when work-
ing with this equipment. Failure to do so could
result in contact with high voltage, which will cause
death or severe personal injury.
