To install the clip leads cable:
1. Insert the female end of the clip leads cable connector into the
clip leads cable receptacle on the terminal with the button facing up
(Fig. 3-1). Make sure the connector is fully engaged.
2. Connect the clip leads to the signal wires between the device and
the 250 ohm resistance. The clip leads connect across the signal
leads independent of signal direction or polarity. Refer to Figures 3-2
and 3-3.

1. Fully depress and hold in the button on the top of the clip leads
cable connector.
2. Firmly, but carefully pull the connector from the receptacle.
