1920W UPS error 199 - replacing fuses

Hello Guybrochard,

When you reset the connections are the connectors tight or wiggle?

I am not seeing the location of the fuses but they are probably in the battery tray:

I will note that when it was new under warranty any component failure, including the battery requires a full UPS replacement.

If you are still under warranty please call into Support to set up a service case.

See if the error just needs to be cleared and monitor.

Battery, 6 Cell, Sealed Lead Acid, 2U

Thanks Charles,
The fuses are not on the battery tray (which is just a transparent plastic container for the 6 cells).
I checked the connections on each battery to see if any was loose. Also checked the connector between the battery pack and the unit ...
I already tried to reset the UPS, without making a difference on the error message.
The UPS is few years old, and not under warranty anymore. But it would be a shame (and a waste of money) to just trash it if the problem is simple to solve. Hence the question regarding the fuses ...
Thanks again,
Guy.

Hello Guybrochard,

The fuses should be on the main board. I attached an image of a similar 2400W UPS.

I found them under the plastic sheet covering the front parts.
I'll try to test them, and hope for the best.

Thanks,
Guy

Good morning @Guybrochard  did you change the fuses did that fix the issue?

@Guybrochard​ Did you get to resolve the issue? I am facing the same issue. Thanks.
