Connect control wires as shown in the following figure:
Figure 3.29
To disconnect control wires from the terminals use the procedure described in
enters the terminal with a pair of pliers, then use a straight-edge screw driver to release the terminal and pull the wire out.
If it fits tightly, e.g. if ferrules are used, turn the wire for about 45° and then pull it gently out. Use this procedure to
remove the wire jumper between terminals HC, H1 and H2 that is preinstalled at shipping.

When setting the frequency by analog reference from an external potentiometer, use shielded twisted-pair wires (treating
wire ends as shown in Figure 3.27
