Hot unplugging/plugging a PSU module
Caution:
While it is possible to replace a PSU module with power connected
to the other two, this may cause a momentary interruption or noise
on the audio outputs of the unit. Always mute any loudspeaker
system before performing this procedure.
If you have to replace a PSU module, it can be done with the DL371 Audio System
Engine unit switched on. This is known as “hot unplugging” (removing) and “hot
plugging” (fitting), and will enable you to change it quickly and save you having to
disconnect the cables from the unit.
>> To hot unplug/plug a PSU module
1
Mute all outputs (see Caution above).
2
Switch off the power at the mains power outlet of the PSU you want to remove.
3
Remove the mains IEC connector from the PSU module.
4
Remove the two screws (left side of PSU module) securing the PSU module to the
rear of the unit.
5
Pull out the PSU module, using its handle.
6
Insert the new PSU module.
7
Plug the de-energised mains IEC connector into the PSU.
8
Apply power to the PSU by switching on the power at its mains power outlet.
9
Check for correct operation of the new PSU module. For example, by monitoring
its LEDs (see “psu panel” on page 6 and “Mains input” on page 10).
Equipment disposal
When this equipment has come to the end of it useful life, its disposal may come under
the DIRECTIVE 2002/96/EC OF THE EUROPEAN PARLIAMENT AND OF THE COUNCIL of
27 January 2003 on waste electrical and electronic equipment (WEEE).
Hazardous substances in WEEE contaminate water, soil and air and ultimately put at
risk our environment and health. The directive aims to minimize the impacts of WEEE
on the environment during their lifetimes and when they become waste.
The WEEE directive addresses the disposal of products when they have reached the end
of their life and contributes to the reduction of wasteful consumption of natural
resources. This will help to reduce pollution, and protect the environment and
ourselves.
If this equipment carries a ‘crossed-out wheelie bin’ (shown left), please
do not dispose of WEEE as unsorted municipal waste but collect and
dispose of in accordance with local WEEE legislation. The horizontal bar
underneath indicates that the product was placed on the EU market after
13th August 2005.
