* Derate capacity to 60% of capacity in CVCF mode and to 90% when the output voltage is adjusted to 208VAC

* When using internal batteries from 16-19, the unit will de-rate according to below formula: P=Prating x N/20

* If the UPS is installed or used in a place where the altitude is above than 1000m, the output power must be derated one percent per 100m

* Product specifications are subject to change without further notice
