Thermal Break Installation Instructions:
SMR Splice
Gap Between Rails
Bonding
Secure the Wiley Bonding Jumper to the Rails
using either the SMR Microinverter Mounting Kit
(shown) or by using M8 Nuts and Bolts.
Insure a loop is left in the Bonding Jumper to
allow for thermal expansion and torque to 13Nm
(10 ft-lbs).
See the SMR Rail and Splice Use Case section
for permissible Splice locations.
The maximum permissible continuous Rail run
before a thermal break is 60 feet.
In cases where a thermal break is necessary it
is recommended to use an SMR Splice in
conjunction with the Wiley Bonding Jumper
(WEEBBNDJMP8.0) to insure continuous
bonding across the thermal break.
Insert the SMR Splice into the Rails with a 1-1/4
inch gap between Rails.
Modules cannot be installed over a thermal
break. The row of continuous modules must end
before the thermal break and a new row must
start after the thermal break.
