Pinout on Delta EADP-180BB?

I have a power supply that is rated at 12V on a couple of pins (8 pin connector) but it does not seem to work. I suspect that one pin (called remote) needs to be activated, but I am not sure what would make it stay up. I have included a drawing from the power supply label.

Try connecting 234 and 5 together. If there is a long cable between the supply and the load, then connect 234 and 5 together at the load.

PS. It might need a load to do anything.
