2.5 Power Supply

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!
Your system has not been provided with a AC power cable. Purchase a
AC power cable that is approved for use in your country. The voltage and
current rating of the AC power cable should be greater than the ratings marked
on on the product's electrical ratings label.
Power is provided through a 300 W ATX power supply with wide range input,
IEC 320-C14 connector and mains on/off switch. The power supply is located at
the front to the left of the card cage behind a front panel.

Combined max. output current at +3.3 V and +5 V must not exceed 45 A. For
temperatures <20°C a higher min. output current is required.

2.5.2 Grounding/Earthing

Caution!
The unit is designed in accordance with protection class 1! It must therefore be
operated with protective earth/GND connection. Use only a three conductor
AC power cable with a protective earth conductor that meets the IEC safety
standards!
