Rack Mounting

If multiple high-power amp units are mounted in a rack with poor ventilation, the heat from the amps will cause the
interior of the amp to become very hot, causing the performance of the amps to be impaired. In particular, when
mounting in a rack whose back can not be left open, mount according to the following instructions.

Rack: Leave a gap of 10 cm or more between the rear panel of the rack and the rear panel of the amplifier.
Fan: Use a fan with 1.5 m

/min or more maximum wind and 5 mmH

2

O or more maximum static pressure.

Mounting: Install the fan kit on the top slot or the top panel of the rack and install a blanking panel between two

amps.

Ventilation panel: . The ventilation panel should be a 1U size, and more than 35% of the entire area should be

open.

Example of mounting

The figure on the left below shows an example of a fan kit (panels and two fans) on the top slot of the rack. The fans
are Minebia 3115PS-12T-B30 (with 0.9 m
