    We moved our 3-phase APC SYMSTRF3I UPS to another building, which only has a single phase supply currenlty. Is it possible to power this UPS with just a single phase (UPS will only be supporting 2 servers). If possible could you please let me know how I could connect and power up the UPS. Thanks

    SYMSTRF3I can be used in either 3:1 or 1:1 mode. The SYPM power module is universal and the 3:1 chassis allows for full current to pass through the AC_IN1 bus.

    In 1:1 mode, acceptable nominal input (Hot-Neutral-Ground) would be 220/230/240 as you would expect.

    And the full *3:1* user manual can be found here:

    The full *1:1* user manual can be found here:
