    KL-7220 power supply

    Need some help here

    I have 1 KL-7220 power supply




    to power 2 KL34-170-90 (NEMA 34) Dual Shaft,
    850 oz-in Peak 72V motors

    Instructions are as follows:

    115Vac - 2 red for neutral and 2 black for hot wire.
    220Vac - 1st red for neutral, 1st black to 2nd red,
    and the 2nd black to hot wire

    Question:

    1. How do I know if I need 115Vac or 220Vac

    2 The 2 outputs have ++@-- signs on each port. what is the middle symbol for? can I just run the + to the +18 to 80 VDC on my Gecko 320 and the - to the Power Ground for each of my 2 gecko's?

    Help is much appreciated!

    Ok so I answered some of my own questions,

    I found that if I hook it up to the 115vac setup, I get 75Vdc out. The symbol in between the + and - Looks like a "C" and I get 37 Vdc out of that. What is that for?

    The C stands for common. As wired in this PS it is only a reference point and is not used.
