Three-phase input connection diagram
：
Make sure that the phase sequence is correct for three-phase mains input wiring, If the
phase sequence is wrong, the UPS cannot start up and will emit warning alarm and the
LCD will display "phase sequence error". The N wire of mains input must be connected
to the N terminal of the input for input wiring of the UPS system!
