These amplifiers are designed for wall mount applications but can also be mounted into a
standard 19" rack.
The amplifier will produce heat during operation which will rise and may cause problems for
temperature-sensitive equipment mounted above it. Mount the amplifier near the top of the
backboard (for wall mounting) or rack (for rack mounting) so that no other equipment will be
above it. If this is not possible, then allow at least 12" space (or 7 rack spaces min.) between
the top of the amplifier and the bottom of any equipment positioned above it. Also allow at
least 2" space (or 1 rack space min.) between the bottom of the amplifier and any equipment
below it to allow for adequate air circulation. If mounting the TPU above other heat-producing
equipment, provide at least 6” of space (or 4 rack spaces min.).
Wall Mounting
To wall mount the amplifiers, use the four 5/8" pan head screws with Teflon washers provided
(see Fig. 2). Insert the top two screws first, leaving the heads protruding about 1/4". Lift the
amplifier and place it over the 2 screws using the top keyhole slots in the flanges at the sides
of the amplifier. Allow the amplifier to rest on the 2 screws and then proceed to insert the
bottom 2 screws into the lower keyhole slots. With all the screws in place, tighten the screws
to secure the amplifier.
NOTE:
Backboard must be a minimum of 3/8" thick plywood and securely mounted to the wall.
The TPU35B, TPU60B, and TPU100B require the use of the RPK82 Rack Mounting Kit (sold
separately). Instructions for rack mounting these amplifiers are provided within the RPK82 kit.
Rack Mounting the TPU250
The TPU250 was designed to mount directly, without a rack kit, into standard 19" racks using
the mounting flanges as shown in Figure 3 (rack screws are not supplied). In the factory set
position, the unit will protrude from the front of the rack. This provides the best ventilation of
the unit and easier access to the wiring connections.
The unit can also be mounted with its controls & connectors facing into the rack. This
provides a more flush Panel appearance and keeps all wiring inside the cabinet. Be sure to
follow all ventilation instructions above.
The unit can also be mounted partially recessed in the rack by reversing the mounting
flanges. Unscrew the mounting flanges (3 screws mount the flange to the cover) and install
them in a flipped over orientation. This position will provide adequate ventilation and centers
the weight of the unit over the rack rails.
