Elevated Operating Ambient
If equipment is installed in a closed or multi-unit rack assembly, the operating ambient of the rack may be greater than the room ambient. Therefore, considerations
should be given to the TMRA, or Temperature inside the Mounting Rack, and not just inside the room.
Reduced Air Flow
Installation of the equipment in a rack should be such that the amount of airflow required for safe operation of the equipment is not compromised.
Mechanical Loading
Mounting of equipment in a rack should be such that a hazardous condition is not achieved due to uneven loading. This unit is not very heavy, but total rack loading
should be considered.
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 over-current protection
and supply wiring. Appropriate consideration of equipment nameplate 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 connection to the
Branch (use of power strips).
Desktop Installation
To set up the DTV735 in a desktop environment, place it on a flat surface where it will not be subject to being hit or pushed, and will not have anything spilled or
dropped on it. Also, the cables connected to the unit should be routed so they are not hit or pulled, which might cause damage to the connectors or to the unit itself.
Additionally, there should be sufficient flow of cool air so the unit stays within its operating parameters.
Rack Installation
When installed in an equipment rack, it is best that the DTV735 be supported by angle brackets or cross supports. These should be screwed or bolted securely to the
equipment rack, and be capable of supporting the unit and its connecting cables. Do NOT install the unit if you have doubts about the unit being safely supported. There
are also 4 holes in the front brackets, which are designed to accept screws for further anchoring. It is also essential that these brackets be used so the unit cannot be
moved forward and fall from the rack. It is always best to install the angle brackets or cross-members before setting the unit in place. Then, prior to installing cables,
put anchored screws or bolts-and-nuts into place on the front brackets. Failure to do this can lead to pushing the unit out the front of the rack in later steps.
