The WMS spacer tube will be used to help adhere
the junction box cover and also help guide the
distance in between modules. Take the second
module and line it up so that it is adjacent to
the WMS spacer tube and in line with the first
module installed. Once placed, remove the
adhesive covering and apply pressure to install
the second module. Ensure the junction boxes
on the second modules are on the upward slope
so that they are next to the junction boxes of the
first module installed.
Before installing the last WMS component for the
two modules, connect one of the 8” MC4 jumper
cables. These should be installed on the junction
boxes of the two modules that are opposite the
side of the WMS wire conduit pieces. Using the
7.5’ MC4 jumper cables connect one end to the
module located on the upward slope and run it
through the WMS wire conduit towards the ridge
of the roof. Use another 7.5’ MC4 jumper cable
to connect it to the bottom module and run it
through the WMS wire conduit towards the eave
of the roof.
Take another piece of the WMS wire conduit and
line it up so that the bottom of the component
on the downhill slope is even with the end of the
second module. Remove the adhesive covering
and apply pressure to install the component.
