Precautions when rack-mounting the unit

This unit will operate stably in an environmental temperature of 0–40°C. If you install this device together with

multiple units of the same device or other devices in a EIA standard rack, the heat produced by the various

devices may raise the ambient temperature inside the rack, resulting in inefﬁcient performance. To ensure that the

heat produced by this device can be dissipated appropriately, please ensure the following conditions when rack-

mounting it.

• When mounting this device together with other heat-producing equipment such as power ampliﬁers, leave 1U or more

space between it and other devices (including other ACD1 units). Install a ventilation panel in this vacant space or leave it

open to ensure adequate cooling.

• Leave the back of the rack open, and allow at least 10 cm of space between the rack and the wall and ceiling to ensure ade-

quate cooling. If you’ve installed a fan kit, there may be cases in which closing the back of the rack will produce a greater

cooling effect. For details, refer to the owner’s manual of your rack or fan kit.

■ When mounting the ACD1 together with compatible ampliﬁers

• Do not mount another ACD1 unit or ampliﬁer above or below the ACD1.
