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.
