3.2.2 Base Station Unit Wire Terminations
Two twisted pairs requiredfor connection between the Base Station and the ICC‐2W. These are DC
power and communications. Using the appropriate cable (an IMSA 39‐2 shielded cable is
recommended), carefully strip the multi cable outer jack back approximately five inches (125mm), see
Figure 3.2.2(a), without nicking
or damaging the insulation on the wire pairs inside. Scoring the outer
jacketlightly withasharp knifeandbendingthe outerjacketsheathbackandforthuntilitparts isthe
safest method. Cut the corrugated copper shield and the plastic core wrap flush with the outerjacket
being
careful not to damage the wire pairs. Separate the wire pairs and strip each of the wire’s
insulation back approximately ¼” (6mm). If you are using a cable with more than two pairs cut the

The Base Station assembly is provided from the factory partly assembled. Remove the cap assembly
from the base assembly by turning the cap assembly so the screw heads in the base align with the
keyhole. Re move the cord grip cap and grommet from the assembly by unscrewing it.
