ZEP SYSTEM II INSTALLATION MANUAL
All measurements are from the center of the accessory roof attachment hardware that will attach
to the center of the Leveling Foot slot. The measurement between Row 1 and Row 2 requires an
additional three (3) inches to account for the fact that the leveling feet face down roof on the first
row and up roof on all other rows (Figure 5.4B)
5.5 > Interlocking the First Module Pair
1. Bring the first two Modules on the roof and set them down end-to-end in landscape orientation
or side-to-side in portrait orientation near the SW or SE area of the array (Figure 5.5A). These
instructions assume that you are starting at the SW corner of the array area. Module junction
boxes should be oriented per system design to allow for ease of Module interconnections.
2. Insert the Interlock Assembly in the bottom groove between the Module pair, spacing the Modules
½ inch apart using the two outside alignment marks on the Interlock Assembly (Figure 5.5B).
NOTE:
It is generally much easier if you DO NOT pick up the Modules, but rather leave them
on the roof and insert the Interlock by holding the tongues of the Interlock Zeps.
