Hazardous procedures
In addition to other procedures described in
this instruction manual as dangerous, user
personnel must adhere to the following:
1. Always work only on a de-energized
circuit breaker. The circuit breaker should
be isolated, grounded and have all control
power removed before performing any
tests, maintenance or repair.
2. Always perform maintenance on the
circuit breaker after the spring-charged
mechanisms are discharged (except for
test of the charging mechanisms). Check
to be certain that the indicator flags read
OPEN and DISCHARGED.
3. Always let an interlock device or safety
mechanism perform its function without
forcing or defeating the device.
