Electrical Connections
The figure and tables below detail the connections available internally in the Air XD instrument. The
connections can be accessed by opening the front housing of the instrument using the supplied key.
The connections are clearly labelled on the internal metal plate. Wires are inserted into the connector
terminals by first using a small flat-head screwdriver or dedicated tool inserted into the small recess
above the appropriate terminal. Pushing the screwdriver down into the mechanism opens the connector
terminal allowing the wire to be inserted into the opening. Before placing the wire into the connector,
ensure that the wire has been stripped back sufficiently and crimp attached, where required, to enable
a good electrical connection. Once the wire has been sufficiently pushed into the terminal, remove the
screwdriver to allow the mechanism to clamp the bare wire or crimped end. Give a gentle tug on the
wire to make sure it has been clamped sufficiently by the connector. Ensure mains cables are fixed in
place using the mounting points provided. Details of the connections are given in Tables 1 and 2 below.
