4.4 Power Supply
The system has a 150 W open frame AC power supply with wide range AC input and 12 V DC 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 320-C14 connector, integrated
mains/line fuses, line filter and a mains/line switch.
Fuse value is T2AH250V.

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!
