Documents: documents delivered with the TP481200B, power supply and
distribution device layout diagram, Initial Configuration Parameters for Power
Supply and Distribution Devices, TP482000B V300R002C03 Central Office Power
System User Manual (TP482000B-N20B1, TP482000B-N20B2, TP481200B-N20B1,
and TP481200B-N20B2)
Skill requirement: power distribution engineers
Procedure
Step 1 Measure the input voltage of the AC input circuit breaker. The value ranges from
85 V AC to 300 V AC.
Step 2 Switch on the AC input circuit breaker and measure the output voltage of the AC
input circuit breaker. The value ranges from 85 V AC to 300 V AC.
Step 3 Check that the RUN indicator on the rectifier is steady on.
Step 4 Measure the voltage between the –48 V busbar and the RTN+ busbar. The value
ranges from –42 V DC to –58 V DC.
Step 5 Power on the TP481200B, and view and complete its initial configuration.
● During the TP481200B commissioning process, modify the initial configuration
parameters by referring to the
Supply and Distribution Devices .
● If any alarm is raised, rectify the fault before continuing the commissioning.
Step 6 Set the number N of batteries connected, the rated capacity, and installation time
based on site requirements.
