S&C IntelliRupter PulseCloser Configuration Manual page 5

1 . QUALIFIED PERSONS . Access to an
IntelliRupter fault interrupter must be restricted
only to qualified persons . See the "Qualified
Persons" section on page 2 .
SAFETY PROCEDURES . Always follow safe
2 .
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 .
OPERATING MECHANISM AND BASE .
5 .
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 to do so by
S&C Electric Company .
6 . ENERGIZED COMPONENTS . Always consider
all parts live until de-energized, tested, and
grounded . The integrated power module 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 energized or installed near energized
lines should be considered live until tested and
grounded .
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 .
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 ground for testing, before
energizing an IntelliRupter 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 the local earth ground, or building ground,
cannot be severed or removed .
8 . VACUUM INTERRUPTER POSITION . Always
confirm the Open/Close position 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 .
