2. Reduced air flow — Installation of the equipment in a rack should be such that the amount of air flow required for safe operation of the equipment is not compromised. 3. Mechanical loading — Mounting of the equipment in the rack should be such that a hazardous condition is not achieved due to uneven mechanical loading. 4. Circuit overloading — Consideration should be given to the connection of the equipment to the supply circuit and the effect that overloading of the circuits might have o

Vent Space Vent Space Vent Space Vent Space Vent Space Vent Space Rack Mounting Ventilation Recommendations Excessive heat can decrease the optimal lifetime of the power amplifier. An over temp indicator LED on the front panel of the amplifier lights red whenever the recommended operating temperature has been exceeded (see Front Panel Features and Operation on page 9). To reduce the chances for an over temp condition, the XPAs should be arranged in a rack environment so that adequate airflow
