2.4 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 AC power cable
must be rated for the product and for the voltage and current marked on the
product's electrical ratings label. The voltage and current rating of the cable
should be greater than the ratings marked on the product.
The subrack system has a open frame AC power supply with wide range input.
The power supply is assembled on the bottom-hinged rear panel.
The power input is provided by a AC mains/line module with IEC 320-C14
connector, integrated mains/line fuses and line filter.
A mains/line switch is located at the lower front side.
Maximum fuse values are:
• 8 A (Power supply MP4 in 7 U Systems)
• 10 A (Power supply MP6 in 8 U Systems)
Warning!
The fuse value has been determined in factory for the maximum power
delivered by the power supply. The fuse value must be changed to the actual
current of the complete equipped system.

2.4.1 Grounding

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!
There is a 6,3 mm faston connector at the right side panel. This connector is only
for equipotential bonding. Grounding is achieved through the protective earth
conductor of the power cable!
