Connecting Load to the PDU
Preparing to connect the load to the PDU(s)
See how to punch holes in the top cover in section 1:
Preparing for top cable entry.
Note
Connect the load equipment evenly between the 3 phases to
avoid overloading the PDU. The total output capacity of the
PDU is approximately twice the output capability of the UPS.
This means that UPS would be over-loaded if all PDU outlets
were loaded to their rating. Load status on the individual
phases can be found through the UPS display or through the
web interface.
Note
Equipment connected to the 3-phased output may require
overcurrent protection with a lower rating than the 3-phased
output.
Note
For 3-phased output, the highest current may be in the Neutral
conductor at non-linear loads (up to 173%).
