Thank you for reaching out to the SE Community, my name is Jon and I will assist you with this query. Apologies for the inconvenience this has caused.
I have tried translating your message and hopefully, it was correct. Unfortunately, the fan on the UPS is not user replaceable. If the translation was accurate, the message was that the fan had caused a short circuit to the chassis of the UPS. If this is the case, please do not use the UPS and reach out to our Technical Support team for your country for assistance.
