4.4 Power Supply
The system has a 400 W open frame AC power supply with wide range AC input and 12 VDC output.
The DC output is connected directly to the power management circuitry on the backplane.
The power input is provided by an AC mains/line module with IEC 60320-C14 connector, integrated
mains/line fuses, line filter and a mains/line switch.
Fuse value is T6.3AH250V.

Hazardous voltage!
Parts of the power supply may be exposed with hazardous voltage.
Always remove mains/line connector before carry out any assembly work.
Caution!
The unit is designed in accordance with protection class 1! It must therefore be operated with protec-
tive earth/GND connection. Use only a three conductor AC power cable with a protective earth
conductor that meets the IEC safety standards!
Caution!
There is a ground terminal at the right side. This ground terminal is only for equipotential bonding.
Grounding is achieved through the protective earth conductor of the power cable!
