WARNING
TO PROTECT THE PERSONNEL ASSOCIATED WITH
INSTALLATION, OPERATION, AND MAINTENANCE OF
THESE
CIRCUIT
BREAKER
ELEMENTS,
THE
FOLLOWING PRACTICES MUST BE FOLLOWED:
Only qualified personnel, as defined in the local
electrical code, who are familiar with the installation and
maintenance of medium voltage circuits and equipment,
should be permitted to work on these circuit breaker
elements.
Read these instructions carefully before attempting
any installation, operation or maintenance of these
breakers.
Always remove the breakers from the enclosure before
performing any maintenance. Failure to do so could
result in electrical shock leading to death, severe
personal injury or property damage.
BE EXTREMELY CAREFUL while the circuit breaker is
on the extension rails. Use provided rail clamps to firmly
hold the circuit breaker on the extension rails while
performing such activities as charging, closing and
tripping. Carelessness could cause the circuit breaker to
fall from the rails resulting in personal injury to those in the
area.
Do not work on a closed breaker or a breaker with
capacitor bank charged. The capacitor bank should be
discharged and the main contacts open before working
on the breaker. The capacitor bank will discharge after
control power is removed. Failure to do so could result in
severe injury or death.
Do not use a circuit breaker by itself as the sole means of
isolating a high voltage circuit. Remove the breaker to the
DISCONNECT position and follow good lockout and
tagging rules, as well as all applicable codes, regulations
and work rules.
Do not leave the breaker in an intermediate position in
the cell. Always have the breaker either in the TEST or
CONNECTED position. Failure to do so could result in a
flash over and possible death, personal injury or property
damage.
Breakers are equipped with safety interlocks. Do not
defeat them. This may result in death, bodily injury or
equipment damage.
