Configuration

Connection of Load to the PDU

Connecting load to the PDUs

Connect the load evenly between the 3 phases to avoid overloading one particular single phase. The total output capacity of the PDU is approximately twice the output capability of the UPS, meaning that the UPS would be over-loaded if all outlets were loaded to their

Note rating. Load status on the individual phases can be found through the UPS display or through the web interface.

Equipment connected to the 3-phased output may require overcurrent protection with a lower rating than the 3-phased output.

Note

For 3-phased outputs, the highest current may be in the Neutral conductor at non-linear loads (up to 173%).
