HAZARD WARNING
WARNING:
Low voltage power circuit breakers contain stored
energy spring operating mechanisms. For maximum personnel
protection when installing and testing this retrofit kit,
the following procedures must be followed.
No work shall be performed on an energized breaker.
Only qualified persons, as defined by the National Electric
Code, and preferably NETA Certified Technicians, who are
familiar with the operation and maintenance of low voltage
power circuit breakers should perform the installation of
this retrofit kit.
Completely read and understand all instructions before
attempting the installation and testing of this retrofit
kit. Personnel are available at Utility Relay Company
during normal working hours (Eastern Standard time) to
answer any questions.
Turn off and lockout the power source(s) supplying the
breaker prior to removing the breaker and attempting any
work on the breaker. Follow all lockout and tagging rules
of the National Electric Code and all other applicable
codes, regulations and work rules.
Do not perform any work including charging, closing or
tripping or any other function that could cause significant
movement of a draw out breaker while it is on the extension
rails.
For both draw out and bolt-in breakers, trip open and then
move the breaker to a well-lighted work area with a sturdy
workbench before starting the retrofit.
Do not work on a closed breaker or a breaker with the
closing springs charged. Trip open the breaker and make
sure any stored energy springs are discharged before
performing any work. If this is disregarded, the breaker
may unexpectedly trip open or the charging springs may
discharge, causing severe injuries.
Under some circumstances it may be necessary to charge the
springs and close the breaker to make/verify certain
retrofit adjustments. In those instances, use extreme
caution to stay clear of any moving components in case the
breaker either purposely or unexpectedly trips open or the
charging springs discharge.
Refer to the latest edition of the ANSI/NETA Standard for
Maintenance Testing Specifications for bolt tightening
torque specifications.
