Rack Mounting
The EDGE is designed to be mounted in an industry standard 19" equipment rack, and
requires one rack unit (1.75 inches) of vertical space. The EDGE has a depth of 9-1/2"
behind the rack rails (including chassis connectors). An additional five inches of space
is required for wiring cables to pass through. The chassis has a width of 17-3/8". Space
needed in front of the rack rails is 3/4".
The EDGE has vertical slots positioned in the side panels for venting. Make sure your
installation does not obstruct these slots. There is no fan inside the EDGE because its
power consumption is low enough to not require one.
The EDGE may be mounted between other devices in the equipment rack and in
accordance with good engineering practice should not be mounted directly above devices
that generate significant amounts of heat. If such a location is unavoidable then it is to
utilize an extra 1RU blank rack panel between the WheatNet‑IP and devices immediately
above and/or below it.
WARNING! Under no circumstances should the EDGE unit be opened! The unit
contains high voltage circuits that are hazardous and potentially harmful. The unit
has no user-serviceable parts inside! If you have a problem the unit must be returned
to Wheatstone Corporation for repair.
Installation Tips
• Place any surge protection circuits as close as possible to the EDGE or other device
being protected.
• Establish a low impedance common ground in your facility and try to route all grounds
to that point.
• Choose the best power conditioning / UPS units that you can afford and suitable for
your equipment – focus on the features and options you need. The better UPS products
can prevent thousands of dollars in equipment damage – some even come with an
external equipment damage warranty.
Energizing
Once it has been installed in the rack, the EDGE may be energized by connecting the
factory supplied power cord to a source of AC power. The AC line input voltage is permitted
to be between 90 and 260VAC, 50 or 60Hz. Power consumption is under 100VA.
Aggressive AC input filtering is utilized at the AC input of the EDGE; however, it is
always advisable to use external surge protection and/or an uninterruptible power supply
(UPS), especially where AC power quality is questionable, such as at a remote transmit‑
ter site.
Power conditioning, surge suppression, and even power backup devices are wise
investments when using sensitive modern electronic devices that use an internal computer.
Use of a UPS (uninterruptible power supply) is a good idea and will protect the EDGE
from short duration power interruptions which may cause it to reboot.
