2.4 Mounting and Connection
The RS20i may be mounted in a standard equipment rack or placed on a cabinet.
WARNING: Before powering on the RS20i for the first time, verify that the correct
input voltage has been selected at the rear panel power entry module. Incorrect input
voltage setting will damage the RS20i. See section 2.4.4.
CAUTION: Because power line surges can damage the RS20i, we require the use of
a properly functioning computer-grade surge /spike suppressor. We also recommend
using an uninterruptible power supply (UPS) with minimum 200 VA.
1. Install rack ears (if rack mounting) on the RS20i. These are included in the RS20i packing kit.
2. Install the RS20i into the audio rack, or place on a cabinet.
3. Connect the RS20i to other equipment. (See Appendix A Connector Pin-outs and B Interface
Wiring Diagrams.)
4. Connect the supplied power cable between the RS20i unit and the AC mains source.
2.4.1 Rack/Enclosure Requirements
Follow these recommendations if the RS20i unit will be installed in a closed or multi-unit rack/enclosure
assembly.
• Elevated Operating Ambient Temperature – Determine the operating ambient temperature within
the rack or enclosure, since this may be greater than the ambient temperature in the room. The
maximum ambient temperature for the equipment in a closed or multi-rack assembly is 40°C
(104F°).
• Reduced Air Flow – Ensure adequate airflow for cooling purposes on all sides of the equipment.
Make sure that the ventilation fan is not blocked.
• Mechanical Loading – Mounting of the equipment in a rack should be such that a hazardous
condition is not caused due to uneven mechanical loading.
