Preparing and Wiring the Cables

To prepare and connect cable leads and drain wires, follow these steps:

1. At each end of the cable, strip some casing to expose individual wires.

2. Trim signal wires to 5–inch lengths beyond the cable casing. Strip about 3/16

inch (4.76 mm) of insulation to expose the ends of the wires.

3. At the module–end of the cables:

- extract the drain wire and signal wires
- remove the foil shield
- bundle the input cables with a cable strap

4. Connect drain wires together and solder them to a 3/8” wire braid, 12” long.

Keep drain wires as short as possible.

5. Connect the 3/8” wire braid to the nearest chassis mounting bolt.

6. Connect the signal wires of each channel to the terminal block.
