1) Wiring for single-phase input
Note
※ ：
For the single-phase input wiring, the live (L) wire must be connected to the R-phase of
the input terminals, not to the S or T phase terminal, otherwise, the UPS will consider
the utility power abnormal
2) Wiring for three-phase input
Note
※ ：
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!
Remark: the three phases
are marked with R, S and T.
If adopting A, B and C mark,
the R-phase, S-phase and
T-phase correspond to the
A-phase, B-phase and
C-phase.
