Potential Electrocution Hazard. Always disconnect power to the instrument when making electrical connections.

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

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.

Connectors P8 on the main board (Figure 3 on page 10) and J7 on the measurement board

(Figure 5 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).
