42 Array Controller Enclosure Components
Power Supply Modules
Two separate power supplies provide electrical power to the internal components by
converting incoming AC voltage to DC voltage. Both power supplies are housed in
removable power supply modules that slide into two slots in the back of the controller and
plug directly into the power interface board. See
Figure 14 .
Figure 14 Power Supply Modules
Each power supply uses a separate power cord. These two power cords are special ferrite
bead cords (part no. 5064-2482) required for FCC compliance. Both power cords can plug
into a common power source or each cord can plug into a separate circuit (to provide
power source redundancy).
