Extending the AC Power Cable
The AC-power adapter has a 12’ (4 m) power cable. If you need a longer cable,
you can extend the power cable of the radiation shield using 2-conductor
speaker cable or zip cord with polarizing identification. That is, a zip cord with
one of the wires marked so you can identify the positive (+) and negative (-)
wires. If you plan on using the splice connectors supplied with the radiation
shield, we recommend a wire size of 19-24 AWG (0.9 -0.5 mm) with a maxi-
mum insulation of.082 in (2.08 cm). Connect the additional power cable using
splice connectors as follows:
1. Cut the cable ends square.
2. Separate the wires about 1” on both cables. Do not strip the insulation.
Separating the Wires
3. Take the striped (or otherwise marked) wire from the supplied cable and
place it into one of the holes at the end of a splice connector.
Make sure you push the wire all the way into the connector. You can check
this by looking through the clear side of the splice connector.
4. Take the striped (or similarly marked) wire from the additional cable and
place it into the other hole at the end of the splice connector.
Again, make sure you push the wire all the way into the connector.
Using Splice Connector
5. Use pliers to squeeze the green cap into place, securing the wires.
