Mounting Options
The DSC 3G-HD A and DSC HD-3G A scalers can be mounted by any of the following 
methods:
• 
Rack mounting: Attach the DSC to a standard 19-inch rack shelf. The following 
Underwriters Laboratories (UL) guidelines pertain to the installation of the 
DSC 3G-HD and HD-3G in a rack:
• 
Elevated operating ambient temperature — If the equipment is installed in a 
closed or multi-unit rack assembly, the operating ambient temperature of the rack 
environment may be greater than room ambient temperature. Therefore, consider 
installing the equipment in an environment compatible with the maximum ambient 
temperature (TMA) specified by the manufacturer. 
• 
Reduced air flow — Install the equipment in the rack so that the amount of air 
flow required for safe operation of the equipment is not compromised. 
• 
Mechanical loading — Mount the equipment in the rack so that uneven 
mechanical loading does not create a hazardous condition. 
• 
Circuit overloading — When connecting the equipment to the supply circuit, 
consider the effect that circuit overloading might have on overcurrent protection 
and supply wiring. Consider equipment nameplate ratings when addressing this 
concern. 
• 
Reliable earthing (grounding) — Maintain reliable grounding of rack-mounted 
equipment. Pay particular attention to supply connections other than direct 
connections to the branch circuit (such as the use of power strips).         
• 
Under-furniture mounting: Mount the DSC under the surface of a desk, table, or 
podium. 
• 
Through-furniture mounting: Mount the DSC through a table or desk in which a 
hole has been cut to enable access to the front panel.
• 
Free-standing: Attach the four rubber feet to the bottom of the DSC in the four 
corners and place the unit on furniture as desired.
To mount the DSC using an Extron mounting kit, see the instructions provided with the kit.
