DC power connector on the rear of the controller-drive tray. The three source wires on
the other end of the power connector cable connect the controller-drive tray to
centralized DC power plant equipment, typically through a bus bar above the cabinet.
WARNING (W12) Risk of electrical shock – This unit has more than one power
source. To remove all power from the unit, all DC MAINS must be disconnected by
removing all power connectors (item 4 below) from the power supplies.
