5 Installing in a Rack
This section describes what to do before installing in a rack and how to rack
mount.
Before Installing in a Rack How to Rack Mount
Before installing in a rack, be sure that the environment is
within the recommended range:
To rack-mount a machine:
1. Attach both ear brackets to the
machine. To do so, remove the
screws from each side of the
machine (3 on each side), and
replace those screws through the
ear brackets.
2. Place the ears of the machine
against the rack rails, and insert the
proper screws (not provided)
through each of the four holes in the
rack ears.
Note that:
•In some models, the front panel
may feature built-in rack ears
•Detachable rack ears can be
removed for desktop use
•Always mount the machine in the
rack before you attach any cables
or connect the machine to the
power
•If you are using a Kramer rack
adapter kit (for a machine that is not
19"), see the Rack Adapters user
manual for installation instructions
(you can download it at:
http://www.kramerelectronics.com)
Operating temperature range +5º to +45º C (41º to 113º F)
Operating humidity range 10 to 90% RHL, non-condensing
Storage temperature range -20º to +70º C (-4º to 158º F)
Storage humidity range 5 to 95% RHL, non-condensing
!
CAUTION!!
When installing in a 19" rack, avoid hazards by taking
care that:
1. It is located within the recommended environmental
conditions, as the operating ambient temperature of a
closed or multi unit rack assembly may exceed the
room ambient temperature.
2. Once rack mounted, enough air will still flow around
the machine.
3. The machine is placed straight in the correct
horizontal position.
4. You do not overload the circuit(s). When connecting
the machine to the supply circuit, overloading the
circuits might have a detrimental effect on overcurrent
protection and supply wiring. Refer to the appropriate
nameplate ratings for information. For example, for
fuse replacement, see the value printed on the
product label.
5. The machine is earthed (grounded) in a reliable way
and is connected only to an electricity socket with
grounding. Pay particular attention to situations where
electricity is supplied indirectly (when the power cord
is not plugged directly into the socket in the wall), for
example, when using an extension cable or a power
strip, and that you use only the power cord that is
supplied with the machine.
