6 S&C Instruction Sheet 765-510
Safety Precautions
DANGER
Omni-Rupter Switches operate at high voltage. Failure to observe these
precautions will result in serious personal injury or death.
Some of these precautions may differ from company operating procedures and
rules. Where a discrepancy exists, users should follow their company’s operating
procedures and rules.
1. QUALIFIED PERSONS. Access to switches and
controls 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 AND TAGS. Do not remove or
obscure any of the “DANGER,” “WARNING,”
“CAUTION,” or “NOTICE” labels and tags. Remove
tags ONLY if instructed to do so.
5. ENERGIZED COMPONENTS. Always consider
all parts live until de-energized, tested, and
grounded.
6. INTERRUPTER SWITCH POSITION. Always
confirm the Open/Close position of interrupter
switches by visually observing the position of the
blades. Switches may be energized from either side
and with the blades in any position.
7. MAINTAINING PROPER CLEARANCE. Always
maintain proper clearance from energized
components.
8. OPERATION. Circuit-making and circuit-breaking
are involved in the normal operation of this
interrupter switch and, as a result, “partway”
opening or closing is undesirable. To operate, swing
the operating handle through its full travel vigorously
and without hesitation. See the "Operation" section
on page 31.
