Cables & Connectors
Most cables used throughout the unit are ribbon cables. Cables must be handled with extreme care to avoid
damage. Apply only the tension required to seat or unseat the cables during insertion or removal from the
connector. Handle cables by the connector whenever possible. In all cases, avoid bending, twisting, or tearing
the cables and ensure that the cables are routed in such a way that they cannot be caught or snagged by parts
being removed or replaced.
