-20 to +70 Deg. Centigrade  
5 to 95% RHL, non-condensing  
machine through the ear bracket  
via the spacer, securing both ear  
brackets to the machine.  
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
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.  
2
3
Once rack mounted, enough air will still flow around the  
machine.  
The machine is placed straight in the correct horizontal  
position.  
Note that:  
ñ In some models, the front panel  
may feature built-in rack ears  
ñ Detachable rack ears can be  
removed for desktop use  
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.  
ñ Always mount the machine in the  
rack before you attach any cables or  
connect the machine to the power  
ñ 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:  
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.
