Installing the VP-740 Industrial Version on a Rack
7
5 Installing the VP-740 Industrial Version 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, 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)
