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

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.
To reduce the chances of an over temp condition, the XPA Ultra amplifiers should be
arranged in a rack environment such that the environment around the amplifier does not
reach or exceed +122 °F (+50 °C). No more than four stacks of XPA Ultra amplifiers should
be arranged one-on-top-of-the-other in a rack without an open space between the stacks
(see figure 8 below).
The XPA Ultra can also be arranged above or below another non-XPA Ultra device. In this
case, the environment around the amplifier should not reach or exceed +122 °F (+50 °C).
