3.2 Rack mounting and cooling
Rack mounting
The enclosure provides six different positions for the rack ears
enabling different rack mounting options inside a d&b Touring rack
assembly or any other rack assembly.
The corresponding positions and their intended purpose are shown
in the table below:
Flat:
Intended for any rack assembly.
Pos. 1:
Used when mounted above the I/O panel.
Pos. 2:
Used when mounted above the amplifier.
In addition, the device can also be mounted to the rear of a rack,
provided the required mounting rails are available.
For this purpose the side panels also provide the same mounting
hole options (grid) at the rear as shown in the graphic opposite.
Cooling
Thermal conditions are a vital factor to ensure operational safety of
the device. The DS20 is equipped with an fan that draws cool air
from one side panel into the housing and channel the warm air
towards the rear vents of the device.
▪ Please ensure that adequate cool airflow is provided.
▪ Do not block or cover the rear panel vents on the side panel air
intake.
▪ If the DS20 is installed in sealed cabinets (e.g. in fixed
installations), use additional fan modules with filters that can be
easily replaced without opening the sealed cabinets.
3.3 Mains connection
WARNING!
Potential risk of electric shock.
The device is a protective class 1 unit. A missing earth (ground)
contact may cause dangerous voltages in the housing and controls
and may lead to electric shock.
▪ Connect the device to mains power supplies with protective
earth only.
▪ If there is any sign of obvious damage to the power cord
and/or mains plug, do not use the power cord and replace it
before further use.
▪ Please ensure the mains connector is accessible at any time to
disconnect the device in case of malfunction or danger.
Before connecting the device to mains voltage, check that the
mains voltage and frequency correspond to the specifications on
the rating label above the mains connector socket on the rear
panel of the unit.
A powerCON
®
mains connector socket
[7] is fitted on the rear
panel and an appropriate power cord
[2] is supplied.
