6 S&C Instruction Sheet 766-540
Overview
WARNING
Serious risk of personal injury or death may result from contact with electric
distribution equipment when electrical isolation and grounding procedures
are not followed. The equipment described in this document must be operated and
maintained by qualified persons who are thoroughly trained and understand any
hazards that may be involved . This document is written only for such qualified
persons and is not a substitute for adequate training and experience in safety
procedures for accessing high-voltage equipment .
WARNING
These instructions do
NOT replace the need for utility operation standards . Any
conflict between the information in this document and utility practices should be
reviewed by appropriate utility personnel and a decision made as to the correct
procedures to follow .
The IntelliRupter fault interrupter operates at primary voltage levels . High voltage
may be present during certain disruptions in the wiring system or grounding system
because of a problem in the IntelliRupter fault interrupter itself . For this reason,
access to the fault interrupter should be treated with the same safety precautions
that would be applied when accessing other high-voltage lines and equipment .
Follow all locally approved safety procedures when working on or around the fault
interrupter .
Before attempting to access an existing fault interrupter installation, check
carefully for visible or audible signs of electrical or physical malfunction (do
this before touching or operating the fault interrupter or any other part of the
installation) . These warning signs include such things as smoke, fire, open
fuses, crackling noises, loud buzzing, etc . If a malfunction is suspected, treat all
components of the installation, including the fault interrupter and associated
mounting hardware, as though they were elevated to primary (high) voltage .
Whenever you are manually reconfiguring the circuit (for example, during repairs),
follow your company’s operating procedures to disable automatic operation of the
IntelliTeam® SG Automatic Restoration System . This prevents any unexpected
operation of a team member .
You can disable the IntelliTeam SG Automatic Restoration System by selecting the
Prohibit Restoration option in any member of the team to be disabled .

Applicable Software
Operating Levers—
Hookstick-operated levers are provided for manually opening and
closing the interrupters and for applying and removing a hot line tag. A separate lever,
if provided, blocks tripping on ground overcurrent elements. The integrated disconnect
on disconnect-style models is also hookstick-operated. See Figures 1 and 2 on page 7.
Single-Phase or Three-Phase Tripping—
Each operation of the overcurrent circuit-
testing sequence can be configured for either
Single-Phase Trip
or
Three-Phase Trip
mode. The last test operation specifies whether a
Single-Phase Lockout
operation is
acceptable or a
Three-Phase Lockout
operation is required.
IntelliLink® Setup Software—
IntelliRupter fault interrupters can be configured and
operated locally from the safety and security of a vehicle parked near the base of the
pole by means of a secure Wi-Fi communication link to a laptop computer.
SCADA Operation—
When furnished with a suitable user-specified radio, IntelliRupter
fault interrupters can be operated by a SCADA system using DNP 3.0 Protocol.
IntelliLink Remote Setup Software—
IntelliRupter fault interrupters can be
configured and interrogated remotely using a desktop computer over a communication
system using DNP 3.0 Protocol.
