General Notes:

  1. Switches [Relays] are shown in their inactive [de-energized] state.
  2. Splices may be split across pages for visual clarity with respect to the function displayed on the particular page.
  3. Some connectors are split across multiple pages for clarity.

    There is no overall reference in this document for the signals routed to a specific connector.

  4. Wire sizes are specified in mm^2 cross-sectional area (CSA) per SAE 1127/8
  5. Wire Specification: 60V, thin-wall PVC (ISO type or equivalent).

    Default wire type to be rated 60VDC/25VAC and -40C to 105C operating temperature.

    See DIN 13602 or ISO 6722 for detailed specifications.

  6. Unless otherwise specified at the device pins, terminal plating is to be Tin or Pre-Tin

    TERMINAL PLATING 

    • GOLD TERMINAL NECESSARY

    ■ SILVER PLATING NECESSARY
