Important Notice
The UPS ground (earth) conductor carries leakage current from the loads in addition to any
leakage current generated by the UPS. This UPS generates no more than 1 mA of current. To
limit the total leakage current to 3.5 mA, the load leakage must be limited to 2.5 mA. The
three-wire receptacle that you plug the UPS into must have a good (low-impedance) ground
(protective earth) connection to provide a safe path for leakage current.
