SUA3000RMI2U Wont Turn On

[JCUPS]

Hi all

I have just got a SUA3000RMI2U and purchased new battery's for it and get 50+ volts from them currently.

When I try to switch it on I get a blip sound and nothing else no LEDs etc.. Power is getting to the main board but I cannot locate any Schematics for it to troubleshoot further

I know it's an old unit but you just work with what you have.

Can anyone suggest any possible known issues or components on these that can fail easily I could look too?

Regards

What is the serial number of this unit you’re talking about?

The useable service life depending upon model and production year is 7-10 years.

Connect the system to a computer running APC Power Chute Software or 3rd party like: APCUPSD / NUT.

Call out the active faults / errors present. If the system has a NMC installed upload the following logs for review: Event, Data, UPS.

Show me a photo of the LED display while the system is connected to AC Mains.

Take a video of you turning the system on and focus on the LED display than provide a link to view the same.

Next, take a True RMS Multimeter and measure the output outlets and report the AC value. Follow with setting your meter to DC volts and measure the voltage at the battery terminals while connected to the system.

Disconnect the battery terminals and measure just the output from the systems charging cable and report back the value.

Show me a photo of the rear of the system. On the rear of the unit is a breaker whether it be a button / switch push / toggle it a few times.

If the system has an EPO terminal block insure it’s (NOT) connected to anything and remove the phoenix connector if present.

Cold Start: Insure the battery cartridge is fully charged before proceeding. Follow the steps on page 12 to initiate a cold start of the system and report back the results:
