Note
1. The RDU-A G2 can record and display up to 1000 pieces of PUE historical records.
2. After you perform calculation setting, the system will save a piece of record every 24h according to your configuration.
3. If you do not perform calculation setting, the system will not save the PUE records.
4. If you perform calculation setting but do not perform system load percentage setting, the system will still save the PUE records,
but the load percent will always be 0.

1. Energy Consumption Calculation Setting
1) You can select two types of devices for Energy Consumption Calculation. To facilitate illustration, we define that:
A = Energy Consumption of IT load, B = Energy Consumption of Infrastructure load, C = Energy Consumption of all
devices. The rules are as follows:
If you configure calculating A and B, PUE = (A + B)/A;
If you configure calculating A and C, PUE = C/A;
If you configure calculating B and C, PUE = C/(C - B);
Among the above formula, the valve of A, B or C is the summary of the three signals configured at left side of the
page.
2) Power Mode or Power Consumption Mode
Power Mode
In Power Mode, the system will count an instantaneous valve of device power every 8h from 00:00:00 to 00:00:00 on
next day, and calculate an average valve of a day after three times of counting as the power PUE of that day.
For instance:
In the first counting, the IT load power is (A1) 8kW, and all device power is (B1) 10kW.
In the second counting, the IT load power is (A2) 9kW, and all device power is (B2) 11kW.
In the third counting, the IT load power is (A3) 7kW, and all device power is (B3) 10kW.
