Export performance data.
a. Log in to the ECC800 WebUI as an administrator.
b. Choose Query > Export Data.
c. (Optional) Select Encryption password and enter an encryption password.
Record the password for decompressing the data package.
d. Set Data type to Performance data from the drop-down list box and click Export
Historical Data.
Performance data source: The ECC800 obtains total electricity energy from the power distribution
devices.
e. Select a path to save the exported data to the PC.
Filter performance data of the integrated UPS.
a. Decompress the performance data package and open the perfmg_1_hour.csv file.
In this example, the statistical period of the performance data is 1 hour.
The statistical period of the exported performance data can be 1 minute, 5 minutes, 15 minutes, 30
minutes, 1 hour, one day, one week, one month, and one year.
b. Select Integrated UPS Cabinet 1 for Equipment, and select IT equipment
output total valid energy as well as Total active electricity energy of UPS input
for Performance Data.
Calculate the PUE of the smart module.
a. Calculate increment in the total active electricity energy of the IT load output and
increment in the total active electricity energy of the UPS input.
 In this example, the start time is 18:00 and the end time is 19:00.
Increment in the total active electricity energy of the IT load output = 104665.1 kWh – 104648.7

kWh = 16.4 kWh; increment in the total active electricity energy of the UPS input = 170600.3 kWh
– 170572.6 kWh = 27.7 kWh.
