strain on the connector. Allow enough extra cable to prevent chafing

and kinking in the cable.

Connecting the Communication Cable to the Isolated Link Coupler

Attach the terminal block of the link coupler to the Belden #3106A or

#9842 cable as shown below. Additional terminal blocks are available

for replacement, see chapter 11.
