► Always stay in the safe area during test.
► Prior operation make sure that the test equipment is not mounted within the motion path of the circuit
breaker. If needed, perform an operation prior mounting of test equipment (for example, motion
sensors).
► For defining the appropriate high-voltage test area, consider any potential falling equipment (for
example, the CB MC2 modules or clamps) as well as wrong connected motion equipment.
► Position the test equipment on dry and solid surface.
1.3.4 De-energize the switchgear
► Identify your test object and make sure that you are using the corresponding wiring diagram.
► Disable any charging mechanism (for example, the motor).
► Ensure that the control circuit of the circuit breaker is de-energized (for example, the spring is
discharged).
► Make sure that the circuit breaker cannot be tripped or closed remotely and locally (for example, use
manual controls or distance orders).
► If you have to make connections to the auxiliary circuit (for example, to the trip or close coils):
► Switch off or disconnect the test object from the station supply.
► Apply the five safety rules.
► Use terminal adapters to connect the test leads.
► Only if required for testing, turn the supply back on.
