UNITY 4600 USER’S MANUAL

Mechanical Loading
Rack-mounted equipment should be installed in such a way that a hazardous condition is
not produced by uneven loading. The U4600 unit is not very heavy, but total rack loading
must be considered. Also, do not rest any unsupported equipment on a rack-mounted
U4600 unit.
Circuit Overloading
Consideration should be given to the connection of the equipment to the supply circuit and
the effect that overloading of circuits could have on overcurrent protection and supply wir-
ing. Ensure that the total rack or breaker power consumption does not exceed the limits of
the AC branch circuit. Appropriate consideration of equipment ratings should be used
when addressing this concern.
Reliable Earthing
Reliable earthing of rack-mounted equipment should be maintained. Particular attention
should be given to supply connections other than direct connections to the branch circuit
(use of power strips, chassis ground lugs, etc.).
Rack Mounting the U4600 is sized as a single RU and will fit an EIA-standard, 19-inch-wide equipment
rack.
a. First install angle brackets or cross-supports capable of supporting both the unit
and its connecting cables. Screw or bolt the supports securely to the equipment
rack.
b. Place the U4600 on its supports and use four anchor screws or bolts and nuts to
secure the U4600 front brackets to the rack.
WARNING
The front brackets must be secured to the rack. If the front brackets are left unsecured, the
unit may shift forward and fall from the rack during installation or operation. Failure to
secure the front brackets may result in personal injury and/or damage to the equipment.
Desktop
Installation To set up the U4600 in a desktop environment, place the U4600 on a flat surface where it
will not be subject to spills or impacts. Also route cables to the unit so that they will not be
hit or pulled, causing damage to the connectors or to the unit itself. Ensure a sufficient flow
of cool air (See “Reduced Air Flow” on page13.) so that the unit's operating ambient tem-
perature range is not exceeded.
WARNING
Locate the U4600 and its cables to avoid impacts, spills, and pulling cables and to ensure
sufficient air flow. Failure to locate the U4600 in a proper environment may result in
damage to the equipment.
