Figure 2-7: 3405PSX Power Supply
The 3405PXS unit is an auto-ranging external power supply that automatically senses the input voltage
over the range of 100 to 240 VAC. The 3405PSX is designed to supply power to one 3405FR frame. The
4-pin XLR outlet connects to the 3405FR 12V DC IN #1 connector. For redundant power supply operation
connect a second 3405PSX to the 12V DC IN #2 of the 3405FR.
The 3405PSX external power supply brick has 1 green status indicator LED. The green status indicator
LED indicates fault free operation of the power supply brick and the presence of AC power. The green
status indicator is off is AC power is absent or the 3405PSX is faulty.
Power should be applied by connecting a 3-wire grounding type power supply cord to the power entry
module on the rear panel of each power supply. The power cord should be minimum 18 AWG wire size;
type SVT marked VW-1, maximum 2.5 m in length.
CAUTION - TO REDUCE THE RISK OF ELECTRIC SHOCK, EARTHING OF THE
EARTH PIN OF THE MAINS PLUG MUST BE MAINTAINED
For NEBS compliant installations, the AC power cord of the 3405PSX shall be
connected to an external surge protection device (SPD).
