When rou
ti
ng the cable, leave a foot or so extra at each end to make connec
ti
ons easier.
In most cases, the refrigerator vent is the best place to route the cable from the roof into the RV.
Some RVs have the refrigerator located in a slide-out. In this case, an alternate lo
cati
on will be
required and may require c
reatin
g a roof or front cap p
enetrati
on. This should be performed by a
professional RV technician to ensure a wat
ertig
ht seal.
Starti
ng at the solar panel connec
ti
ons, plan the rou
ti
ng for the Y-cables and connec
ti
on cables
[see below] across the roof to the entry loc
ati
on. Use the provided cable
ti
e mounts and cable
ties
to secure the cable to the roof. Be sure to prepare the roof surface in the same manner as
already described for ensuring good panel and edging adhesion prior to
sti
cking down the cable
tie
mounts.
o
A cable
ti
e mount must be placed directly adjacent to each side of each pair of cable
connectors, at the center of each “Y” cable (where the three cables join in the middle)
and then at least every 4’ along the roof to the point of entry. Use add
iti
onal mounts
anywhere the cable is not well supported. Add
iti
onal cable
ti
e mounts can be purchased
at your local hardware store if needed.
