Notes:
• Verify that junction box PCB is 63-1170-01 (bottom center).
• Microcells A and B are on one support leg.
• Microcells C and D are on another support leg. Microcells C and D can be wired as shown, or can be wired to its
own junction box (terminals A and B) if desired.

8. Perform Steps 2 through 7 for each Microcell you wire to this
junction box (up to four).
9. Spread a generous bead of sealant (Sikaflex 1A polyurethane
sealant or Dow Corning RTV 739 or RTV 738) around the sides of
the plug for each hole not being used. Screw a plug into each hole.
10. Replace the junction box cover and screws if not ready to begin
wiring the junction boxes together, to ensure no moisture enters the
junction box.
There are two versions of the junction box enclosure. Both versions
have four small holes for wiring Microcells to the junction box, as
described above. In addition, the junction box has one or two large
holes:
• One large hole for conduited installation — The large hole, which
accommodates a
3 /
4
” conduit fitting, is for wiring the junction box to
the other junction boxes and to the signal processor.
• Two large holes for non-conduited installation — The two large
holes, which are equipped with PG13.5 cable fittings, are for wiring
the junction box to the other junction boxes and to the signal
processor. KM requires the use of cable trays for non-conduited
installations.
