1.
Check that the voltage and frequency are in normal operating ranges.
Measure the upstream input line voltage using a multimeter. The line voltage is in the range of
342–456 V.
Measure the upstream input frequency using a multimeter. Frequency range for the 50 Hz scenario:
47–53 Hz. Frequency range for the 60 Hz scenario: 57–63 Hz.
2.
Switch on the input circuit breaker in the smart busway.
If the air conditioner and the lighting system are powered by the PDB, skip powering on them.
Step 2
(Optional) Switch on the light output circuit breaker in the power distribution unit of the smart
busway, and check that the PWR indicator on the AC actuator lights up, press the light button
to power on lights.
Step 3
(Optional) Switch on the air conditioner output circuit breaker in the power distribution unit
of the smart busway to power on the air conditioner.
Step 4
Switch on the network cabinet output circuit breaker in the power distribution unit of the
smart busway and switch on the rPDU input circuit breaker in the network cabinet to power
on the network cabinet.
Step 5
Switch on the IT cabinet output circuit breakers in the power distribution unit of the smart
busway one by one and switch on the rPDU input circuit breaker in the IT cabinet to power on
the IT cabinet.
While switching off output circuit breakers, check that their mapping relationship with downstream
devices is consistent with the design.
Do not switch on reserved circuit breakers.
When switching on a circuit breaker, observe whether there is any abnormal phenomenon, for
example, the circuit breaker cannot be switched on or off smoothly or sparks occur.
Step 6
The Branch Disconnected alarm generated for a reserved circuit breaker can be masked on the
ECC800 WebUI.
