3. Pass the power cable through the end plug (1), the main body (2), and the cable clamp (3), and
then connect the three wires (live, neutral and earth) to the connector (4) as follows:
1. Live (brown)
2. Neutral (blue)
3. Not used
Earth - Earth (green and yellow)
Note: The numbers and earth symbol are stamped on the end of the connector. Ensure it is connected
correctly.
4. Slide the cable clamp (3) back onto the connector (4) and tighten the screws on the clamp to
secure the cable.
5. Screw the two parts (4) and (2) back together.
6. Secure the power cable by screwing the end plug (1) back in place.
7. The female connector can now be plugged directly into the instrument power connector. The two
connectors are grooved to avoid an incorrect fitting. Tighten the female connector to the
instrument power connector finger-tight.
4.7 Connections to electronic boards
Potential Instrument Damage. Delicate internal electronic components can be damaged by static electricity,
resulting in degraded performance or eventual failure.
Note: Any loose connection wires should be bundled tightly together with the use of nylon cable ties.
4.7.1 Sensor cable
An ORBISPHERE cable is needed to connect the sensor to the instrument. There is a cable gland for
cable passage, and the cable must be permanently connected to the measuring board connector. A
sensor cable is required with free wires on the instrument end. The free wires are connected to the
connector J8 on the measuring board, as detailed later in this chapter.
