8. Connect CIBANO 500 to the trip and close coils of the circuit breaker for all phases according to the
wiring diagram displayed in Primary Test Manager and the following figure.
Figure 17-24: Typical measurement setup for the Timing test
For the circuit breakers with one drive for all three phases connect the trip coil to B1, the close coil to
B2, and the common connection of the trip and close coils (typically the battery minus) to BN. In general,
the motor of the HV circuit breakers remains connected to the station battery throughout the test and a
current clamp connected to BN and B4 is used to record the motor current.
