Hardware installation
The Relay – 8 is designed to be mounted in a rack or as a stand-alone unit on a desk, drawer or
alike.
Make sure there is at least 40 mm of free space above the unit as air circulation around the unit
is needed for reliable performance. If installed in a closed environment forced air circulation may be
needed.
Mounting the unit in a 19” rack
The Relay – 8 can easily be installed in a 19” rack.
Due to the standard 1U height, low weight and small mounting depth the Relay – 8 can be
mounted from the rack front without the use of a rack shelf or supporting rails.
