Rack Mounting Ventilation Recommendations - Extron electronics XPA Ultra Series User Manual

5. Either attach the false front panel, which is provided with the rack shelf, to the
unoccupied side of the rack, or install a second half rack-width device to that side.
Repeat steps 1 through 4 if a second device is being installed.
6. Attach the rack to the shelf by using the four 10-32 x 3/4" screws provided with the
shelf. Insert the screws through #10 beveled washers, then through the holes in the
rack (see figure 4).

Rack Mounting Ventilation Recommendations

Excessive heat decreases 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.
The XPA U 3502 amplifier needs to be arranged in a rack environment, so that the
environment around the amplifier does not reach or go beyond +122 °F (+50 °C). No more
than four amplifiers should be stacked vertically without an open space in between, as seen
in figure 5.
Figure 5.
The XPA U 3502 amplifier can be arranged above or below another non-XPA Ultra device.
The environment around the amplifier should still not reach or go beyond +122 °F (+50 °C).
