Power Supply Wiring
In this section you will connect all the wires emanating from the power supply module, and even add a few
more by installing the transformer. The tangle of wires can look foreboding, but they are well-marked and
clearly identifiable in the following steps. An overview of the wiring before installing the power transformer is
shown in Figure 45 on page 31. However, you should install the wiring following the steps below to avoid
mistakes that could do serious damage to your KPA500.
Connect the four-wire cable from the power supply module to the power entry module as shown in
Figure 41. This cable has four heavy wires: black, yellow, blue and white with the white wire at the top. The key
prevents installing the plug incorrectly.

Locate the long three-wire cable attached to the power supply module. Route this cable around the front of
the Z-bracket and plug it into the 3-pin connector on the front of the PA/LPF assembly near the right side panel
as shown in Figure 42.
