4. Installation and Connection
4.1 Setup Location
The TOPAS should be installed in a dust free environment, if possible.
Warning
Condensation water might damage the device.
As you unpack the device, note the difference between the amplifier and ambient
temperature. At a high temperature difference, you have to wait a sufficiently long time
before you take the device out of plastic wrap.
The humidity should not exceed 80%.
The ambient operating temperature should not exceed 40°C (see page 14). If necessary,
cool the environment of the location with suitable equipment. If the TOPAS overheats, it
automatically switches to the error mode.
From 95°C operating temperature of the TOPAS volume controls automatically shut down by
6 dB.
Caution
To avoid overheating, do not adjust the volume somewhere else in the audio system. The
device would automatically switch to the error mode and should be cooled down and reset
for subsequent operation.
Do not install devices in any of the following places:
• where the devices are permanently exposed to direct sunlight.
• near other heat sources or open fire.
• where the airflow for cooling is blocked.
• where the devices are exposed to high moisture.
• where the devices are exposed to strong vibrations and dust.
Do not put liquids on or near the device.
4.1.1 Rack Mounting
The TOPAS is intended to be mounted in 19” racks. It requires two rack units (88mm) with an
installation depth of 455mm.
When mounting the amplifier in the rack, ensure adequate ventilation in front of and behind
it. The cooling air is taken in through the front and the heated air is rejected out the back.
Ensure that the TOPAS is safely mounted in the rack. Fasten the device on the front (rack
bars) and on the back with four adequately dimensioned screws each.
The vents may not be blocked or closed.
