KRAMER: SIMPLE CREATIVE TECHNOLOGY
Installing on a Rack
6 Installing on a Rack
This section describes what to do before installing on a rack and how to rack
mount.
Before Installing on a Rack
Before installing on a rack, be sure that the environment is
within the recommended range:
Operating temperature range +5 to +45 Deg. Centigrade
Operating humidity range 5 to 65% RHL, non-condensing
Storage temperature range -20 to +70 Deg. Centigrade
Storage humidity range 5 to 95% RHL, non-condensing
CAUTION!!
When installing on 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 supply connections other than
direct connections to the branch circuit (for example, the
use of power strips), and that you use only the power cord
that is supplied with the machine.
How to Rack Mount
To rack-mount the machine:
1 Attach both ear brackets to the
machine. To do so, fasten the 5
screws on each side of the
machine through the ear bracket
via the spacer, securing both ear
brackets to the machine.
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
