WARNING
Dangerous electrical voltage!
Do not attempt to install or perform maintenance on
equipment while it is energized. Death or severe injury
can result from contact with energized equipment.
Always verify that no voltage is present before proceed-
ing. Always follow safety procedures. Eaton is not liable
for misapplication or misinstallation of its products.
Observe all recommendations, notes, cautions, and
warnings related to the safety of personnel and equip-
ment. Observe and comply with all general and local
health and safety laws, codes, and procedures.
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 unneces-
sary 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 discon-
nected cell 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 not required to provide current protection
features. Protection is active well below any overload. The
trip unit begins to power-up at very low levels of current at
approximately 40 A.
