Procedure
Step 1 Measure the input voltage on the AC input circuit breaker. The value should range
from 85 V AC to 300 V AC.
Step 2 Switch on the AC input circuit breaker and measure the output voltage on the AC
input circuit breaker. The value should range from 85 V AC to 300 V AC.
Step 3 Check that the Run indicators on PSUs are steady on.
Step 4 Measure the voltage between the −48 V busbar and RTN+ busbar. Ensure that the
voltage is in the range of −42 V DC to −58 V DC.
Step 5 Power on the TP48400B, and view and complete its initial configuration.
● During the TP48400B commissioning process, modify the initial configuration
parameters by referring to the power supply and distribution device initial
configuration table.
● If any alarm is raised, rectify the fault before continuing the commissioning.
Step 6 Set parameters such as Battery connected, Rated capacity, BLVD Enable,
Installation Time, and Volt. Detect Mode based on the actual configurations.
