Capacity and topology

Suitable environments and limits

This unit suits server rooms and network closets that require rack or tower mounting and 120 V input with a wide voltage window. Sites needing longer runtime at full load or USB and network management cards should look at other models.

Questions about this item

What input voltage must my building supply for the OL8KRTHD to run at full 100 % load?

The UPS accepts 180-280 VAC for 0-100 % load; below 180 VAC the allowable load drops in steps down to 25 % at 120-139 VAC.

Can I keep using my existing NEMA L6-20P and L6-30P server cords with the six outlets on this unit?

Yes, the rear panel provides four NEMA L6-20R and two NEMA L6-30R receptacles that match those plugs directly.

How do I confirm the UPS is delivering clean sine-wave power after installation?

The front LCD shows real-time output voltage and frequency; a steady 120 V reading with the "Online" icon lit confirms correct operation.
