Note:
The three source wires on the DC power connector cable (–48 VDC) connect the
controller-drive tray to centralized DC power plant equipment, typically through a bus bar
located above the cabinet.
Note:
You do not have to connect the second DC power on each of the drive tray’s DC power-
fan canisters. The second DC power connection is for additional redundancy only and can be
connected to a second DC power bus.
5. Have a qualified service person connect the other end of the DC power connector cables to the
DC power plant equipment as follows:
a. Connect the brown –48 VDC supply wire to the negative terminal.
b. Connect the blue return wire to the positive terminal.
c. Connect the green/yellow ground wire to the ground terminal.
