APC Smart UPS 1500 Lights Blink Problem Solution (Relay Fault) MODEL: SUA 1500I

[@Real_serdique]

Hello Mr. Apc fix I wanted to ask you this question since can I know the function of the variable found on the battery compartment of the sua 750i because I changed my the batteries to lithium ion so it’s normal lead acid battery is 27.3 volt and lithium ion 28.9 volt. Can it be the charging voltage variable? If no please tell what’s that.

[@ApcFix]

Use Teraterm software for this purpose.

I see you answer to comments, so there's something I want to ask: some time ago, I replaced the batteries in my apc ups 1500 with 2 victron superback batteries, 12V 20Ah, and did a recalibration via discharging the batteries. Everything went good, but when the low voltage kicked in, both load and battery leds were blinking together. All 10. I know the batteries were low because I restarted the ups and the vacuum cleaner I used as load powered on just for a split second and that was it. This time however, leds didn't started to blink. Ups was stuck on battery led plus one led to battery. Now to the question: what these 10 leds ( load plus battery available capacity ) blinking together is supposed to mean? Calibration failure or something like that?

Please share short video of this fault on my email address, email mentioned in about section.

@ApcFix ok, I will, but I don't know when. Currently, my life is extremely busy

Hi @Apc Fix, found your video looking for solution for my SMT750i. I have opposite problem actually, it faults with "Output over volt" error while a main line goes down (power is disconnected). I cannot find any service manual describing the problem. Can you maybe have some advice? Thanks in advance.

[@ApcFix]

First of all, sorry for the late reply. I only make videos on the SUA series. I have no solution for this problem.

Hello, Mr APC. My smartups has the same issue. I watched the video and saw that ralay has 6 pins, but the link you have supplied is for an eight pin relay, which one is the correct? Sorry for any english mistake.

[@ApcFix]

Some models use a 6-pin relay, and some models use an 8-pin relay. Both are correct, if your model use 6-pin relay then remove two pins from 8-pin relay. For your kind help see these 2 photos in the given below link: drive.google.com/file/d/1kNR25gG1SG6I63OtqdbzBKzu3zUlGMJb/view?usp=drive_link

[@danielpfmarinho]

@@ApcFixthx for previous reply. One more question: you showed 2 types of relay, one with a single line and the other with a double line. Can I use either one? Or is there one of them that is correct?

[@ApcFix]

@@danielpfmarinho Only use double points rely for light blink issue. Double point relay has different from single point relay in term of connection type. I showed single point relay for information only.

What does it mean when all LEDs are flashing on the right side from the on/off button?

[@ApcFix]

This issue happen due to AC output capacitor fault.

[@alexm1736]

@@ApcFix you are right. I change the capcitor and now it works. Thank you

[@Real_serdique]

Hello APC fix actually can you help me by trying this task, Just try in pluging your apc calibrated ups of it then cold start it without it being plug to mains. Then tell me the output frequency whether it is 50 or 60hz.

[@ApcFix]

Email me a picture of the front of the UPS. Email given in about section.

[@Real_serdique]

@@ApcFix I din't see the email I'm a little bit far from it but it's SUA series 700va smart sine wave.

[@Real_serdique]

What I meant is that I just want to change it output permanently frequency to 50Hz so I can on it in 50Hz eve if there is not mains available. Please read it carefully.
