WARNING: Voltages inside the power supply CAN & WILL KILL YOU! You MUST also know how

to work around HIGH VOLTAGE safely. If you do not, get assistance from someone who does.

PRELIMINARY INFORMATION

Determine the operating status of the power supply before beginning this upgrade. Is the power supply

working now? You need to know where you are starting from or you may have difficulty finding your way

home again.

This module was specifically designed for an easy retrofit into the Swan 117C power supply.

The instructions are step-by-step. It is strongly recommended you read the entire document before you

begin and read each step completely before starting the step. There may be a bit of information gleaned

at the end of the step that you wished you had just a minute earlier. The process of labeling or tagging

wires is strongly recommended on any repair or rebuild project. Wires are color coded but it is a good

idea to label them anyway as referenced in the instructions. Masking tape and a ball point works fine.

( )

Read, re-read and fully understand these instructions prior to beginning this upgrade. Be

sure to perform the steps in the order they are listed. Also, be sure to label wires as they are

disconnected from various points inside the power supply. This will help when the time comes to

re-attach the wires that will be disconnected during installation of the module.

TOOLS THAT YOU WILL NEED TO PERFORM THIS UPGRADE

Long nose pliers

Side cutters, flush cutters, or lead trimmers

Page 2 ES4117C POWER SUPPLY MODULE INSTALLATION INSTRUCTIONS Unplug the AC power cord from the mains outlet and allow time for the high voltage to discharge to 0 VDC. Disconnect the remote power supply cable from the Swan radio. Do not plug in the power cord and re-apply power until you have completed the installation, inspected it and removed any short circuits and stray wire clippings.

Page 4 Unsolder and remove the original AC line cord wire (probably BLACK) from terminal strip lug #1 and clean any excess solder from the lug. Unsolder and remove the original ceramic disc capacitor lead from terminal strip lug #1. Unsolder and remove the other lead of the original ceramic disc capacitor from the ground lug and clean any old solder from the lugs.
