Unity 4600 User's Manual
To avoid damage to this and other equipment, or personal injury, the following
items should be strictly observed.
Elevated Operating Ambient
When equipment is installed in a closed or multi-unit rack assembly, the
operating ambient of the rack environment may be greater than the room
ambient. Therefore, consideration should be given to the ambient air
temperature within the rack, and not just inside the room, when deciding if the
maximum recommended ambient operating temperature (T
Reduced Air Flow
Equipment should be installed such that airflow required for safe operation of
the equipment is not compromised. The U4600 may be arranged in a rack
without empty spaces between units if heat rise is prevented by ensuring its
side vents remain unblocked with adequate clearance around the vent holes.
Mechanical Loading
Mounting of the equipment in a rack should be such that a hazardous
condition is not produced by uneven loading. This unit is not very heavy, but
total rack loading must be considered. Also, do not rest any unsupported
equipment on your U4600.
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 wiring. 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.).
