STEP 16. INSTALL EW BRACINGS WITH EQUAL OR UNEQUAL SPAN DISTRIBUTION
Using L-Feet and rail, attach EW Bracings at bays specified by the Ascender Design tool. The orientation of the EW Bracing at the two ends should be in accordance
with the shown direction on Fig. K. Based on thermal break, the last bay either East bay or West bay (based on side you start) may have a different span. In case
of an array with only two spans and two EW bracings, then mount EW bracing in same orientation as shown in Fig. M. Check the Ascender Design tool for these
occurrences.
The red arrow in the above figure shows the view direction of
the observer for Fig. K, Fig. L and Fig. M.
STEP 17. CANTILEVER LENGTH LIMIT CHECK
See Figure L. Maximum length of the cantilever beam should be 1/3rd of the span and minimum
cantilever should be 12.7 cm. Refer to the Ascender Design tool for span chart details.

Note: Ensure that tilt legs are vertical when tightening EW bracing to L-feet.
