SAFETY INSTRUCTIONS
Read these instructions, and follow them.
n Water and moisture
The DNS 8D must not be exposed to rain or moisture. Furthermore, if it is
brought directly from a cold environment into a warm one, moisture may
condense inside it. This, in itself, will not cause damage, but may cause
electrical shorting. This could damage the unit, and even cause danger to life.
Always allow the unit to reach ambient temperatures naturally before connecting
the mains power.
n Mounting and ventilation
You should place the DNS 8D on a at, stable surface or mount it in a standard
19” equipment rack. Use the supplied rubber feet to avoid scratching the
surface, or the rackmounting accessories, as appropriate.
Do not subject the unit to strong sunlight, excessive dust, mechanical vibration
or periodic shocks. It is not susceptible to excessive heat build-up, but should
be installed away from heat sources such as radiators and audio devices that
produce large amounts of heat.
n Power sources
The DNS 8D features a universal AC power supply that will work safely on any
mains supply in the range 85V to 260V, 50/60Hz AC only. A unit used in this way
should always be grounded (earthed), and you should route power cables so
that they will not be walked on or pinched. Unplug the supply cord to isolate the
apparatus from the supply if it is not to be used for some time. Grasp the supply
cord by the plug, never by the cord itself.
A nominally 12VDC input that accepts 8V - 18V DC is also provided.
n Connections
Turn off the power to all equipment before making any connections.
In order to comply with EMC regulations, you must use metal-shelled connectors
and good quality shielded cable suitable for AES3 connections and good quality
CAT6 network cable for Ethernet connections.
n Cleaning
Clean the DNS 8D only with a dry cloth. Never use abrasive pads, water or
liquid cleaners such as alcohol or benzene.
n Damage requiring service
The DNS 8D contains no user-serviceable parts and should on no account be
opened or dismantled by unauthorised personnel.
A unit should be returned to qualied service agents when it has been exposed
to liquids, when it fails to function correctly, when it has been dropped, or when
the case is damaged.
