Type DHP-VR breakers are equipped with high
speed, high energy operating mechanisms. They
are designed with several built-in interlocks and
safety features to provide safe and proper
operating sequences.
WARNING
TO PROTECT THE PERSONNEL ASSOCIATED WITH
INSTALLATION, OPERATION, AND MAINTENANCE
OF
THESE
BREAKERS,
THE
FOLLOWING
PRACTICES MUST BE FOLLOWED:
•
Only qualified persons, as defined in the National
Electrical Safety Code, who are familiar with the
installation and maintenance of medium voltage cir
cuits and equipment, should be permitted to work on
these breakers.
•
Read these instructions carefully before attempting
any installation, operation or maintenance of these
breakers.
•
Always remove the breaker 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.
•
Do not work on a breaker with the secondary test cou
pler engaged. Failure to disconnect the test coupler
could result in an electrical shock leading to death,
personal injury or property damage.
•
Do not work on a closed breaker or a breaker with
closing springs charged. The closing spring should be
discharged and the main contacts open before work
ing on the breaker. Failure to do so could result in cut
ting or crushing injuries.
•
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 all lock-
out and tagging rules of the National Electrical Code
and any and 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.
•
Always remove the maintenance tool from the breaker
after charging the closing springs.
•
Breakers are equipped with safety interlocks. Do not
defeat them. This may result in death, bodily injury or
equipment damage.
