live parts of electrical equipment
• The skills and techniques necessary to determine the proper approach distances
corresponding to the voltages to which the qualified person will be exposed
• The proper use of the special precautionary techniques, personal protective
equipment, insulating and shielding materials, and insulated tools for working on
or near exposed energized parts of electrical equipment
These instructions are intended only for such qualified persons. They are not
intended to be a substitute for adequate training and experience in safety procedures
for this type of equipment.

Special Warranty
Provisions
The standard warranty contained in S&C’s standard conditions of sale, as set forth in Price
Sheet 150, applies to the IntelliRupter fault interrupter and its associated options, except
for the control group (the protection and control module and communication module).
For these devices, the rst paragraph of said warranty is replaced by the following:
(1) General: The seller warrants to the immediate purchaser or end user for a period
of 10years from the date of shipment that the equipment delivered will be of the
kind and quality specified in the contract description and will be free of defects of
workmanship and material. Should any failure to conform to this warranty appear
under proper and normal use within 10 years after the date of shipment, the seller
agrees, upon prompt notification thereof and confirmation that the equipment has
been stored, installed, operated, and maintained in accordance with recommenda-
tions of the seller and standard industry practice, to correct the nonconformity
either by repairing any damaged or defective parts of the equipment or (at the
seller’s option) by shipment of necessary replacement parts. The seller’s warranty
does not apply to any equipment that has been disassembled, repaired, or altered by
anyone other than the seller. This limited warranty is granted only to the immedi-
ate purchaser or, if the equipment is purchased by a third party for installation in
third-party equipment, the end user of the equipment. The seller’s duty to perform
under any warranty may be delayed, at the seller’s sole option, until the seller has
been paid in full for all goods purchased by the immediate purchaser. No such delay
shall extend the warranty period.

Safety Information
WARNING
ELECTROCUTION HAZARD
Failure to follow these instructions can cause serious injury or death.
• This IntelliRupter®PulseCloser®Fault Interrupter must be installed, grounded
and operated ONLY by qualified personnel familiar with high-voltage electrical
equipment, associated safety practices, and potential hazards.
• Before energization, and at all times when energized, the IntelliRupter fault
interrupter base must be connected to a suitable earth ground at the base
of the pole in accordance with the S&C instruction sheet furnished with this
device.
• The IntelliRupter fault interrupter base ground must also be connected to the
system neutral. If the system neutral is not present, proper precautions must
be taken to ensure that the local earth ground cannot be severed or removed.
• To ensure safe and effective installation and operation, follow procedures
in the S&C instruction sheet furnished with this device EXACTLY.
• For additional S&C instruction sheets, call 1-773-338-1000.

Safety Precautions
DANGER
IntelliRupter PulseCloser Fault Interrupters operate at high voltage. Failure to
observe the precautions below will result in serious personal injury or death.
Some of these precautions may differ from your company’s operating procedures
and rules. Where a discrepancy exists, follow your company’s operating procedures
and rules.
1. QUALIFIED PERSONS. Access to an IntelliRupter
fault interrupter must be restricted only to qualified
persons. See the “Qualified Persons” section on
page 2.
2. SAFETY PROCEDURES. Always follow safe
operating procedures and rules.
3. PERSONAL PROTECTIVE EQUIPMENT. Always
use suitable protective equipment, such as rubber
gloves, rubber mats, hard hats, safety glasses, and
flash clothing, in accordance with safe operating
procedures and rules.
4. SAFETY LABELS. Do not remove or obscure any
of the “DANGER,” “WARNING,” “CAUTION,” or
“NOTICE” labels.
5. OPERATING MECHANISM AND BASE.
IntelliRupter fault interrupters contain fast-moving
parts that can severely injure fingers. Do not remove
or disassemble operating mechanisms or remove
access panels on the IntelliRupter fault interrupter
base unless directed by S&C Electric Company.
6. ENERGIZED COMPONENTS. Always consider all
parts live until de-energized, tested, and grounded.
The integrated power module (IPM) contains
components that can retain a voltage charge for
many days after the IntelliRupter fault interrupter
has been de-energized and can derive a static
charge when in close proximity to a high-voltage
source. Voltage levels can be as high as the peak
line-to-ground voltage last applied to the unit. Units
thathavebeenenergizedorinstallednearenergized
lines should be considered live until tested and
grounded.
7. GROUNDING. The IntelliRupter fault interrupter
base must be connected to a suitable earth ground
at the base of the utility pole, or to a suitable building
groundfor testing, before energizing anIntelliRupter
fault interrupter, and at all times when energized.
The ground wire(s) must be bonded to the
system neutral, if present. If the system neutral is
not present, proper precautions must be taken to
ensure that the local earth ground, or building
ground, cannot be severed or removed.
8. VACUUM INTERRUPTER POSITION. Always
confirm the Open/Closeposition of each interrupter
by visually observing its indicator.
Interrupters, terminal pads, and disconnect blades
on disconnect style models may be energized from
either side of the IntelliRupter fault interrupter.
Interrupters, terminal pads, and disconnect blades
on disconnect style models may be energized with
the interrupters in any position.
9. MAINTAINING PROPER CLEARANCE. Always
maintain proper clearance from energized
components.

Overview
An IntelliRupter PulseCloser Fault Interrupter with
catalog number sufx -P300 or -P350 is shipped with the
external power supply assembly packed in a separate box
inside the crate.
The external power supply mounting bracket
is bolted to the bottom of the IntelliRupter
fault interrupter crossarm base, and the junction box is
mounted on the IntelliRupter fault interrupter pedestal.
The power supply slides into the mounting bracket, and
must be grounded to the IntelliRupter fault interrupter
base. See Figure 1 and Figure 3 on page 9.
Figure 1. The external power supply installed on a pedestal-
mounted IntelliRupter fault interrupter.
Two control power sources can be wired to the junc-
tion box, and the secondary source only replaces the
primary source if the primary source is not powered. The
secondary source can be connected to either ac control
power or dc substation battery power.
The external power supply can be installed on
IntelliRupter fault interrupters that also have one or two
integrated power modules. The external power supply is
used when power is not supplied by the integrated power
module(s).
