5. Place Ballast
Tip:
The Racking Construction Set identifies where Ballast is to
be installed. Mark the roof with chalk to speed up installation.
5.1 Install a Rail onto array in locations where Ballast is required.
Bolt to both Module Connectors and tighten to
6 ft-lb.
ALERT:
Every Rail must be fastened to two Module Connector
assemblies.
Tip:
Ballast and Rails are only placed on “S” spacings. Center
Rails on the “S” spacing.
5.2 Place Ballast onto Rails. If rapid cyclic movement of system is
expected e.g. due to seismic activity or building vibration from
activities within or nearby the structure, bend the Rail tabs to
secure Ballast.
ALERT:
Install Mechanical Attachments before going to next
step. See: 9910047 - Accessories Installation Manual
