  1. Hi from Marco.
    I just bought on Ebay a used 1999 made APC USV SU3000INET, but it has
    arrived faulty (maybe the shipment was too rude).
    Assistance is unuseful (no warranty, no repair avalaible!).
    The only choice they gave me is a trade-in for a new model!!!

    Is there anyone who has the schematics/help/any useful tip about
    reparing this model of UPS?

    Please, help me, I wish to use it for other than iron heavy garbage!!!

    Thanks,
    Marco
     
  2. Can you be a little more specific, there is a power on self test built in.

    You may have a tripped circut breaker or a set of bad batteries or they are
    unplugged.

    APC has a pdf of what the front panel lights and switches mean and do.

    Most of these units that are for sale used have weak or dead batteries.

    DigiKey has replacements at just over $20 each, they require 4 12 V 17 A gel
    cells.

    Just picked up a SU3000 and a SU2200 three weeks ago replaced all batteries
    and they are running just fine.

    No there are no schematics available, APC has a firm policy of never
    releasing them.

    have you checked the batteries?
     
  4. Hi from Marco and thanks for You answer...

    .... but, yes, batteries are ok.
    I own two other same model, and I can exclude the batteries are the
    problem, as the other basic items (cables, visually black/blown
    components...)

  5. 1. Are the batteries connected internally? Usually they ship disconnected.

    2. Is this model designed for your market? If the voltage and frequency
    don't match it wont work? 50Hz 60Hz??

    3. Are the batteries any good? A used unit probably has defective
    batteries but otherwise may work OK.

    4. You will never find schematics nor is APC much help other than to
    sell you a new one.

    The APC Smart-UPS will not even power up its outputs if the batteries are in
    such a state they cannot hold a charge at all. It makes them look dead,
    although they are usually fine and operate correctly once the batteries are
    replaced.
     
  7. Thanks for You help... but, I have 2 more units and I already tried
    swapping the batteries. The problem it isn't in the batteries, but
    somewhere in the board (already checked cables and trasfos).

    Thanks,
    Marco
