Hello,I have APC Smart-UPS 1500 (SMT1500i) and it started to behave abnormally.
When it enters battery mode the ups starts to produce very loud and disturbing cracking/rattling noise like there is something in the case trying to escape. The whole UPS vibrates very powerfully and on top of that, there is a sparkling sound like a Bengali fire.
After a while (sometimes very soon, sometimes not) it shut downs with a message on the display "No output volt" and the red LED is lit.
I've reinstalled batteries few times and also tore it down but it's looking like new under the hood.
I have the same problem
Please guide mehttp://fiammco.ir
if the unit is sparking you should turn it off and stop using it. Also, if the unit is less than 3 years old you should contact local support. Explain to them what is happening and request a replacement. You will find local support contact information at this link http://www.apc.com/bg/en/support/contact-us/index.jsp
Hello, I appreciate your answer.
The sparkling sound is only an audible problem, there are no actual sparks.
