2.Connect a DC power cable to the first power supply and to a power outlet.

Note – Use only the DC power cables provided with the array.

Caution – If the array is connected to DC power sources not within the designated – 48V DC (–36 VDC to –72 VDC) range, the unit might be damaged.

Note – To ensure power redundancy, be sure to connect the two power supply modules to two separate circuits (for example, one commercial circuit and one UPS).

Note – To extend the length of the DC power cable as needed, strip the last 1/4 inch of the cable, insert the stripped end into a provided Panduit tube, and crimp the tube.

3.Tighten the cable-locking screws to attach the cable securely to the power supply power outlet.

4.Connect the second power cable to the second power supply and to a second power outlet. Tighten the cable-locking screws.

If one power supply fails, the second power supply automatically takes the full load.
