Installation
Positioning the Amplifier
The KXPA100 amplifier may be mounted vertically or horizontally as shown in Figure 1. Four bushings are
provided for attaching the amplifier to a bracket if needed. The bushings are threaded for 8-32 screws. Do not
use screws that extend inside the amplifier more than 1/8” (3.2 mm).
Be sure the location allows you to access both the front and rear panels of the amplifier. If you connect the
amplifier using the KX3 to KXPA100 Adapter Cable as described on page 13, you won’t need access to the
front panel in normal operation but being able to see the indicators may be useful for troubleshooting if
something is not working properly.
CAUTION
Ensure air can flow freely along the fins as the amplifier warms up in use. Do not
place anything on the fins that can restrict the air flow. Leave at least 3” (7.6 cm)
clear above the fins and at least 1.5” (3.8 cm) clear along the sides.
