SECTION 2: SAFE PRACTICES
The circuit breakers are equipped with linear actuator
operating mechanisms. They are designed with built-in
safety interlocks to provide for safe operation. In
addition, other optional interlocks are available
depending upon the application. Refer to Section 5 for
additional interlock information. It is the customers'
responsibility to insure that appropriate interfaces with
the breakers are provided and tests conducted to
adequately prove proper installation and functioning.
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 Local
Electrical Codes, who are familiar with the
installation and maintenance of medium voltage
circuits 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 drawout type breakers from their
enclosure before performing any maintenance.
Failure to do so could result in electrical shock
leading to death, severe personal injury and/or
property damage.
Always make sure that primary and secondary
power is disconnected from a fixed breaker before
performing any maintenance. Failure to do so could
result in electrical shock leading to death, severe
personal injury and/or property damage.
Do not work on a closed breaker or a breaker with
closing springs charged. The closing springs should
be discharged and the main contacts open before
working on the breaker. Failure to do so could
result in cutting or crushing injuries.
Do not use a circuit breaker by itself as the sole
means of isolating a high voltage circuit. As
appropriate, use an isolation means and follow all
lock-out and tagging rules of the Local Electrical
Codes and any and all applicable codes,
regulations and work rules.
Always ensure that drawout circuit breakers are in
one of their designed cell positions, such as
Connect, Test/Disconnect or Remove. A circuit
breaker permitted to remain in an intermediate
position could result in control circuits being
improperly connected resulting in electrical failures.
Breakers are equipped with safety interlocks. Do
not defeat them. This may result in death, bodily
injury and/or equipment damage.
Do not work on a circuit breaker while suspended
from a lifting means. Maintenance work should be
performed on a properly supported cart or table.
