SOutput overcurrent protection and disconnect switch must be provided by others.
STo comply with international standards and wiring regulations, the sum of the leakage current of the UPS and the total equipment connected to the output of this UPS must not have an earth leakage current greater than 3.5 milliamperes.
SIf installing optional rackmount EBM(s), install the EBM(s) directly below the UPS so that all wiring between the cabinets is installed behind the front covers and is inaccessible to users. The maximum number of EBM(s) per UPS is four.
