Warning!
A CyberPower Step-Down Transformer is required for supplying 120V output to connected equipment. To
prevent damage to connected equipment, do not attempt to separate the output voltage, from the hardwire
block or outlets, into two 120V outputs on this UPS. If you attempt to supply two separate 120V outputs to
your equipment, that equipment can be damaged when the UPS switches to battery mode.
