Strip off 23 mm (0.9 ins.) of shielding from the power cable. Cut back the live and neutral wires to
15 mm (0.6 ins.) in length but leave the earth wire as is. Strip off a small amount of external
insulation from the three wires as required.
2.
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.
3. Loosen the screws on the cable clamp (3) to allow enough room to pass the power cable through.
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. Screw the two parts (4) and (2) back together.
5. Secure the power cable by screwing the end plug (1) back in place.
6. 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.
