Note: 1. Where a sensor is earthed locally, either to the Earth Stud or
through the sensor casing or mounting, to avoid earth loops
the screen sheath of the cable should only be connected at
one end. ie. At the sensor or at the Interface/relay Card.
2. The Optima analogue output is non isolated and is factory
