SAFETY PRECAUTIONS
•
Periodic testing of this devise is required (see Section 6 “Set-
ting and Testing the RSM”).
•
Only qualified persons, as defined in the National Electric Code,
who are familiar with the installation and maintenance of power
circuit breakers and their associated switchgear assemblies
should perform any work associated with these breakers.
•
Completely read and understand all instructions before attempt-
ing any installation, operation, maintenance, or modification of
these breakers.
•
Always turn off and lock out the power source feeding the
breaker prior to attempting any installation, maintenance, or
modification of the breaker. Do not use the circuit breaker as
the sole means for isolating a high voltage circuit. Follow all
lockout and tagging rules of the National Electric Code and all
other applicable codes, regulations, and work rules.
•
Do not work on a closed breaker or a breaker with the closing
springs charged. Trip (open) the breaker and be sure the stored
energy springs are discharged before performing any work. The
breaker may trip open or the charging springs may discharge,
causing crushing or cutting injuries.
•
For drawout breakers, trip (open), and then remove the breaker
to a well-lit work area before beginning work.
•
Do not perform any maintenance: including breaker charging,
closing, tripping, or any other function which could cause sig-
nificant movement of the breaker while it is on the extension
rails. Doing so may cause the breaker to slip from the rails and
fall, potentially causing severe personal injury to those in the
vicinity.
•
Do not leave the breaker in an intermediate position in the
switchgear cell. Always leave it in the connected, discon-
nected, or (optional) test position. Failure to do so could lead
to improper positioning of the breaker and flashover, causing
death, serious personal injury, and / or property damage.
•
Do not defeat any safety interlock. Such interlocks are
intended to protect personnel and equipment from damage due
to flashover and exposed contacts. Defeating an interlock
could lead to death, severe personal injury, and / or property
damage.
WARNING
POWER CIRCUIT BREAKERS ARE EQUIPPED WITH HIGH SPEED,
HIGH ENERGY OPERATING MECHANISMS. THE BREAKERS AND
THEIR ENCLOSURES ARE SIGNED WITH SEVERAL BUILT-IN INTER-
LOCKS AND SAFETY FEATURES INTENDED TO PROVIDE SAFE AND
PROPER OPERATING SEQUENCES. TO PROVIDE MAXIMUM PRO-
TECTION FOR PERSONNEL ASSOCIATED WITH THE INSTALLATION,
OPERATION, AND MAINTENANCE OF THESE BREAKERS, THE FOL-
LOWING PRACTICES MUST BE FOLLOWED. FAILURE TO FOLLOW
THESE PRACTICES MAY RESULT IN DEATH, PERSONAL INJURY, OR
PROPERTY DAMAGE.
