Installation
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:
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.
3.8 Connections to electronic boards
Note: Any loose connection wires should be bundled tightly together with the use of nylon cable ties.
3.8.1 Sensor cable
An ORBISPHERE cable is needed to connect the sensor(s) to the instrument. The table
instruments have a Lemo 10 connector where a sensor cable has to be connected. The other
versions have a cable gland for cable passage, and the cable must be permanently connected
to the corresponding measuring board connector.
Therefore the table instruments require a standard sensor cable, while the other versions
require a sensor cable with free wires on the instrument end. The free wires are connected to
the connector J8 on the corresponding measuring board, as detailed later in this chapter.
3.8.2 Electronic boards connectors
Connectors P8 on the main board, and connectors J7 and J8 on the measurement board(s) are
made of two parts. Push down carefully the black levers on either side of the connector and pull
it out securely. Perform all connections with these connectors unplugged. Once finished, attach
the connectors to the boards by pushing them firmly in place (levers up).
1) Live (brown)
2) Neutral (blue)
3) Not used
Earth (green and yellow)
Note: The numbers and earth
symbol are stamped on the end of
the connector. Ensure it is connected
correctly.
