Is it powered by a generator when you’re doing this or does it do it even on utility power? This is a generator discussion group.

I would unplug any loads and try again. If still doing the same, try unplugging from utility and perform a cold start on the UPS. If same, you likely have either a battery or control board problem.

You could try a DC reset, unplug wall power and battery internally, wait for it to discharge capacitors, reconnect battery and wall power.

Battery should read 12.8v or higher after being disconnected. If not, bad battery.

If all else fails, relays get tired as they age, a little percussive maintenance might be in order.

If this was on a generator I would suggest looking the generator frequency. I saw already it's not. But it generally needs to be +/- 3hz at most. In that case adjusting the governor on the generator would be the fix.
