Instruction manual
Failure to maintain the equipment can cause death, serious injury,
property damage, or product failure, and can prevent successful
functioning of connected apparatus.
The instructions contained herein should be carefully reviewed,
understood, and followed.
The maintenance tasks in Table x must be performed regularly.
The use of unauthorized parts in the repair of the equipment or
tampering by unqualified personnel can result in hazardous conditions
that can cause death, serious injury, or property damage.
Follow all safety instructions contained herein.
Inspection and maintenance intervals
Periodic inspections and maintenance are
essential to obtain safe and reliable operation
of the type SDV-R distribution circuit breaker.
The following procedures along with the
troubleshooting chart at the end of this
section, provide maintenance personnel with
a guide to identifying and correcting possible
malfunctions of the type SDV-R distribution
circuit breaker.
When type SDV-R distribution circuit breakers
are operated under “usual service conditions,”
maintenance and lubrication is recommended
at five-year intervals or at the number of
operations indicated in Table 3: Maintenance
and lubrication intervals, whichever occurs
first. “Usual” and “unusual” service conditions
for outdoor medium-voltage circuit breakers
are defined in ANSI/IEEE C37.04 and ANSI/
IEEE C37.010. Generally, “usual service
conditions” are defined as an environment in
which the equipment is not exposed to
excessive dust, acid fumes, damaging
chemicals, salt air, rapid or frequent changes
in temperature, vibration, high humidity and
extremes of temperature.

Hazardous voltages and high speed moving parts.
Will cause death, serious injury or property damage.
Do not work on energized equipment and SDV-R integral ground switch
is not meant to be a personnel safety ground. Always de-energize and
ground high-voltage conductors before working on or near them. The
user must make all ground connections before making high-voltage
connections, adjust the circuit breaker height to ensure compliance with
safety codes for electrical clearance, and assure that the arc-exhaust
vents are at least 79” (2.0 m) above finished grade.
