Connecting Dc Power Cords; Disconnecting A Dc Power Cable - R/Evolution 2000 Series Getting Started Manual

Connecting DC Power Cords

If your 5730 or 5130 enclosure uses DC power rather than AC power, two DC
power cords (part number 35-00000223) are packaged with each DC enclosure.
1. Use only the DC power cables provided with the array.
2. Check the DC cable part number and wire labels carefully before connecting the
cable to the source.
3. Connect a DC power cable to the first power supply and then to a power outlet.
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.
4. Tighten the cable-locking screws to attach the cable securely to the power supply
power outlet.
5. Connect the second power cable to the second power supply and to a second power
outlet.
6. Tighten the cable-locking screws.
If one power supply fails, the second power supply automatically takes the full load.

power supply.
2. Loosen the cable-locking screws attaching the D-shell connector to the power-and-
cooling module.
