Smart UPS 3000xl and electric generator.

[Anonymous user]

Hi, we have two problems with a Smart UPS 3000 XL
1) The UPS continues to transfer online to battery power when powered by our HONDA EG 6500 CXS (5KVA) electric generator.

2) We do not have the cable to connect the UPS and be able to configure it, to adjust the voltage distortion (possible cause of the problem).
Anyway, we need the cable or the pin out scheme to make the cable.

From now on I am very grateful for any help or suggestion.

Which SmartUPS 3000XL? There are several generations now. What's the actual tag on the UPS say? What connector does it use? If it's a D9 there are plenty of places on the net you can find the cable pinout (the APCUPSD manual is one a quick search will turn up).

Unless your Honda is an inverter gen, you might struggle. The UPS will look at both the voltage and (more importantly) frequency variation and if it moves around much it'll just keep transferring to battery. Some of the older gen of UPS had a button and LED on the back you could use to change the sensitivity settings also.

I recall a few years ago now running an SU2200 on a standard gen but I recall having to keep a very stable load to allow the UPS to charge the batteries. I switched to a cheap inverter gen and haven't had an issue since.

Thanks you Brad

Your help was really helpful.

The UPS model is Smart 3000XLI.

As you said, it has the led and the button to adjust the sensitivity. ( https://imgur.com/RYoBQPi )

I looked in the documentation ( https://www.apc.com/shop/fi/en/products/APC-Smart-UPS-XL-3000VA-230V-Tower-Rack-Convertible/P-SUA300... ).

but I didn't see anything on how to use the led and sensitivity button.

And the same for the cable or pinout of the DB9

Could you help me with these things?

Thanks a lot!

Typical Schneider web page. Missing any useful information. Use the manual for the SUA3000 - Page 9. https://download.schneider-electric.com/files?p_enDocType=User+guide&p_File_Name=ASTE-6YWRZE_R1_EN.p...

Brilliant. Thanks for coming back to say so. Many people don't come back with a "that worked", so this makes it useful for others in the future. Glad I could help.
