Mounting Location
Each junction box can be wired to a maximum of four Microcells:
•
Vertical Microcells — one junction box can be wired to Microcells
from two support legs (two Microcells on each support leg) if the
legs are sufficiently close to each other to allow the Microcell
cables to reach.
See Figure 6-15. Locate the junction box on the support leg or on a
brace. Vertically, locate junction boxes at a convenient height, approxi-
mately 4’ (1.2m) from the ground. The exact location of the junction box
is not critical, but ensure you have sufficient cable length and that a
drip loop will be formed by the Microcell cables when wired to the
junction box.
Junction Box Installation
CAUTION
Do not install junction boxes in the rain. Moisture in the
junction box will cause corrosion and system errors.
Note
Junction box mounting hardware is not supplied by KM. KM
recommends #8-32 socket head cap screws and flat washers. The
instructions below reflect this recommendation.
1. Remove the junction box cover.
2. See Figure 6-16. Hold the junction box at the previously marked
mounting location. Mark the two center mounting holes.
