Easy UPS SMV fan turns on occasionally

[Sentimental]

I recently got SMV 1500VA Line Interactive, and I noticed that every 20-30 mins fan turns on for 2-3 seconds and it stops again. May I know the reason for such event Is it normal for the fan to turn on every now and then?

UPS Load is on 10% on Idle and when opening heavy load it ranges from 25% to 29%, temperature is always stable at 86 F

Hi @Sentimental 

Thank you for reaching out to the SE Community, my name is Jon and I will assist you with this query.

Apologies for the late revert, I understand that you would like to know the reasons or causes of when would the fan turn on in your SMV UPS.  Will you be able to provide the exact model of the UPS?

I have provided an FAQ below but this doesn't mention the SMV models, once I have the model of your UPS I can dig into this more.

Hi @RMZahn 

I have tried looking into this but wasn't able to find the info, I suggest that you contact our local Technical Support for your country for them to raise it to our UPS Experts.
