Check Operation Method
Item
Circuit ● Verify the circuit breaker
breaker labels by referring to the
status power supply and
distribution system
diagram.
● Verify that circuit breakers
can be smoothly switched
on and off.
● Check the circuit breaker
status.
Phase Verify the phase sequences of
sequence upstream and downstream
power distribution devices for
the FusionDC1000 using a
phase sequence meter.
Voltage Use a multimeter to measure

3 Preparations for Power-On Commissioning
Expected Result
● Circuit breaker labels are
correct, clear, complete,
and attached properly.
● Ensure that all load
circuit breakers are
reliable and controllable.
● All PDF, PDB, and PDU
circuit breakers are in
the OFF state, and all
SPD circuit breakers are
in the ON state.
The phase sequences are
consistent.
The voltage is in the range
of 342–418 V.
● Frequency range for the
50 Hz scenario: 49–51
Hz
● Frequency range for the
60 Hz scenario: 59–61
Hz
