Westinghouse Solar Module Torque Specifications
Westinghouse Solar Splices require 5-7 ft/ lbs of torque to fully engage in the east/ west
direction. As an approximation, once you feel the Westinghouse Solar splice fully seated, turn
the Westinghouse Solar wrench 1/8 of a turn, this will create the appropriate amount of torque
for the connection of modules in the east/ west direction.
Installing the First Row
Prepare the module by inserting 3/8" hex bolts into the top and bottom Groove of the module
frame. Position the first module above the first and second row of L Brackets using two people
to carefully lower the module into place. 3/8" hex bolts are adjusted inside the Groove to line
up with the L Bracket fork. 3/8" Flange Nuts are threaded onto the 3/8" hex bolts loosely, to
allow height adjustment and array leveling. The module will temporarily rest on with the 3/8"
hardware left loose. Prepare for the installation of a second module by threading two splices
into the splice channels at both the top and bottom of the frames longer edge. The splices are
used to interconnect the neighboring modules in the east/ west direction. When tightened
simultaneously, the two splices will draw two modules together. Leave the inverter wiring
harness on the roof surface where it will be accessible after a second module is installed.
