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 0.5 mA of current
(U model), or 1 mA of current (E model). To limit the total leakage current to 3.5 mA, the load
leakage must be limited to 3 mA on the U model and 2.5 mA on the E model. If you do not
know the load leakage current, replace the UPS power cord with a power cord that uses a locking
plug with a minimum rating of 10 A (such as IEC 309). If you do not have a matching
receptacle, consult an electrician to install the proper receptacle. 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.
