Note:
The two UPS rear panel output receptacles are supplied from the UPS inverter
section through separate 15A output fuses (
applies to the 1500, 2000, and 2400
VA models only
). Thus, an overload on one of the receptacle sets can cause a
loss of power to it while the other receptacle set remains active. If all of the UPS
indicator lights appear normal and power is not available at one of the receptacle
sets, check the associated output fuse.
