Section 2: Installation
2.1 System Hardware Mounting and Grounding
The JSD-80 is designed to mount in a standard 19" rack, and is two standard rack spaces (3-1/2") high. We recommend vented panels above and below whenever space permits. Mounting the unit immediately above a major heat-producing component
(such as a power amplifi er) is not recom-
mended. The JSD-80 includes a three-prong grounding plug and a three-wire power cord to accommodate a safe ground path from the chassis to the electrical system ground. Defeating this ground by removing the ground prong is not recommended.
2.2 System Cooling and
Ventilation
Important
Care should be taken to insure the JSD-80 has adequate ventilation for cooling during operation. It is recommended that one rack space below the JSD-80 is left open to allow outside air circulation through the unit. A ventilation panel, USL, Inc. part number
VP-1,isrecommendedforprojectionbooths where the normal ambient temperature
exceeds specified equipment operating temperatures listed in the safety section of this manual. Also, it is recommended that equipment with no more than a nineinch depth be mounted directly above the
JSD-80 to insure adequate airfl ow through the unit’s rear ventillation slots.
