WARNING
Do not attempt to install, test, or perform
maintenance on equipment while it is energized.
Death or severe personal injury can result from
contact with energized equipment. De-energize
the circuit and disconnect the circuit breaker
before performing maintenance or tests. Any
tripping operation will cause disruption of service
and possible personal injury, resulting in the
unnecessary switching of connected equipment.
Testing a circuit breaker while it is in-service and
carrying load current is not recommended. Testing
of a circuit breaker that results in the tripping of
the circuit breaker should be done only with the
circuit breaker in the test or disconnected cassette
positions or while the circuit breaker is on a test
bench.

WARNING
Electrical shock or burn injury can occur when
working on power systems. Always turn off the
main power that is supplying the circuit breaker
before conducting tests. Test out of the cell, if
possible.
CAUTION
Exercise care when replacing the battery to ensure that
it is installed correctly. Accidentally installing the battery
in the reverse direction will not harm the trip unit nor the
battery but will defeat the function of the battery.
IMPORTANT
Auxiliary power is required to provide protection features.
