* Brake connections require an additional cable, and are only required for servo motors with an integral holding brake.

Bare wires (power and encoder shields) should be covered with heat shrink.

Make sure you slide the threaded collar, plastic sleeve, back shell, and rubber strain relief onto both cables before you start soldering!
