Installation | 
  | 
Mounting | The amplifier is designed for wall mount applications but can also be mounted in a  | 
  | standard 19" rack. The TPU250 amplifier weighs 31 lbs.  | 
  | NOTE: The amplifier will produce heat during operation which will rise and may  | 
  | cause problems for   | 
  | 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" between the top of the amplifier and the bottom of any equipment  | 
  | positioned above it. Also allow at least 6" between the bottom of the amplifier and  | 
  | any equipment below it to allow for adequate air circulation.  | 
Wall Mounting | To wall mount this unit, use the four 5/8” pan head screws with nylon washers  | 
  | provided (see Figure 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.  | 
Rack Mounting | The amplifier was designed to mount directly to 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.  | 
  | NOTE: 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.  |
