Lightning driver problems

I have 3 Atreum 288.2 boards. As per the website I am pairing a HLG 320-54B with then. For the life of me I can’t get them to power on.
I have no problem powering the lights with a HLG 320-C1400B. So I know the boards are wired correctly. Any clues or thoughts on what the problem might be?

Are they wired in series or parallel? I’m pretty sure I’ve read that some driver/board combos will only fire if wired in one way or the other.

you would need to wire them all in parallel to that 320-54b driver.

The HLG-320H-1400B has an output of 114-229 volts so the boards are wired in series.
The HLG-320H-54B has an output of 54 volts so they would be wired in parallel.
Each panel needs 54 volts.
Why replace a 320 watt driver with another 320 watt driver...curious...lol

Guessing op has the other one driving some other lights and just used it to check if the boards worked

Thanks for all the advice. I switched the wiring from series to parallel and they are working now.
