Hach-Lange ORBISPHERE 510_51x Basic User Manual - Manual (Page 9)

Prepare the user-supplied power cable as follows:
1. Strip off 23 mm (0.9 ins.) of shielding from the power cable.
2. Cut back the live and neutral wires to 15 mm (0.6 ins.) in length but leave the earth wire as is.
3. Then strip off a small amount of external insulation from the three wires as required.
Wire the female connector as follows:
1. Take the narrow end of the connector (4) in one hand and the main body (2) in the other and
unscrew the two. Pull away the cable clamp (3) and unscrew the end plug (1) to reveal the four
parts that make up the connector.
2. Loosen the screws on the cable clamp (3) to allow enough room to pass the power cable through.
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.
Connections to electronic boards
N O T I C E
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.
Sensor cable
An ORBISPHERE cable is needed to connect the sensor(s) to the instrument. The portable
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 portable 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 measuring board, as detailed later in this
chapter.
Electronic boards connectors
Connectors P8 on the main board ( Figure 3 on page 10) and J7 and J8 on the measurement board
( Figure 5 on page 11 and Figure 6 on page 11) 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).
