INSTALLATION This UPS is designed for data processing equipment. Maximum load must not exceed that shown on the UPS rating label. Do not connect equipment that could overload the UPS or draw half-wave current from the UPS, for example: electric drills, vacuum cleaners, laser printers or hair dryers. Your total load earth leakage current must not exceed 3.5 mA. Most data processing equipment meets this requirement if you use no more than two pieces of equipment.
4. Shut down the load equipment and turn off the mains supply. Unplug the load equipment’s power input cable from the mains supply socket and plug it into the UPS input socket. Plug the power input cable into the mains supply socket. Connect the supplied output cable between the load equipment input socket and one of the UPS AC output sockets. Connect all load equipment to the UPS in this manner. 5. Plug any computers and monitors into the orange battery backed up receptacles.
