WARNING
TO PROTECT THE PERSONNEL ASSOCIATED WITH
INSTALLATION, OPERATION, AND MAINTENANCE OF THESE
CIRCUIT BREAKERS, THE FOLLOWING PRACTICES MUST BE
FOLLOWED:
•
Read the instruction booklet provided with the
VR-Series circuit breaker before attempting any
installation, operation or maintenance of these
circuit breakers.
•
Only qualified persons, as defined in the National
Electrical Safety Code, who are familiar with the
installation and maintenance of medium voltage
circuits and equipment, should be permitted to
work on these circuit breakers.
•
Always remove the circuit breaker from the
enclosure before performing any maintenance.
Failure to do so could result in electrical shock
leading to death, severe personnel injury or
property damage.
•
Do not work on a circuit breaker with the
secondary test coupler engaged. Failure to
disconnect the test coupler could result in an
electrical shock leading to death, personnel
injury or property damage.
•
Do not work on a closed circuit breaker or a
circuit breaker with closing springs charged.
The closing spring should be discharged and the
main contacts open before working on the circuit
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.
Remove the circuit breaker to the Disconnect
position and follow all lockout and tagging rules
of the National Electrical Code and any and all
applicable codes, regulations and work rules.
•
Do not leave the circuit breaker in an
intermediate position in the cell. Always have the
circuit breaker either in the Test or Connected
position. Failure to do so could result in a flash
over and possible death, personnel injury or
property damage.
•
Always remove the maintenance tool from the
circuit breaker after charging the closing springs.
•
Circuit breakers are equipped with safety
interlocks. Do not defeat them. This may result in
death, bodily injury or equipment damage.
