APC SmartUPS 3000VA

Hi, i'have an APC SmartUPS 300VA 220V (SUA3000I) that died due to lightning in the mountains.

i'm trying to repair it, but i need wiring diagram. do you have it?
i've not found a diode bridge, and i don't understand it.
The capacitor on 220V input C113 was broken.
The fuse (100A) on battery ground was broken also.
The rest of mainboard seems to be ok.
Can you help me, please?

APC do not release cct diags and these are not easy to repair, if the battery fuse was open and there is some board damage, the thing is toast. Even if you get it going the battery will not be able to be calibrated, unless there the board/processor is 100%, I know this as we have a similar model on the bench right now with new batts in and the unit will not recalibrate, so even though the batts are new, as soon as the mains is dropped it goes to very low battery and shuts down in 2 mins.

Buy a new UPS save yourself a lot of time. Hope this helps

Thanks for using FixYA

APC SMARTUPS 1500VA Battery Problem When Replaced

You are correct. The APC Smart line has a partial charge when it's new. Similar to cordless phones, the work right away, but you're still supposed to charge them before use for best results.

Just leave it plugged in with no load for a couple hours and it will be fine.

Problem with SmartUPS SU5000I

Before trying to replace an IC, make sure that the battery is capable of holding a charge. If there is more than 1 battery, check all. If it (they) are bad, it will probably be less expensive to replace the unit.
