This UPS can be configured for two different applications. Please refer to below wiring diagrams.
Terminal Block wiring diagram for three-phase input
Terminal Block wiring diagram for single-phase input
NOTE 1: Make sure that the wires are connected tightly with the terminals.
NOTE 2: Please install the output breaker between the output terminal and the load, and the breaker
should be qualified with leakage current protective function if necessary.
NOTE 3: This UPS is equipped with phase auto adapt function for input. This function allows UPS to adapt
input phase sequence automatically. Therefore, this UPS can accept either three-phase or single-phase
input power. Please refer to above wiring diagrams for the connection. However, it never accepts two-phase
input power.
