STEP II
INSTALLING THE AC MODULES ONTO THE RACKING SYSTEM
When the mounting rack is fully secured to your roof, you are ready to install AC
Modules.
Refer to the rack installation manual for details on mounting the modules to the rack
system.
ORIENTATION AND CLEARANCES
AC Modules must be mounted in a manner that allows airflow under the PV panels.
NOTE!
AC Modules are convectively cooled. No fan or other mechanical
means is provided to move the air. Do not block the air flow path.
NOTE!
Minimum clearance distances must be observed if your AC Module
inverter system is to operate at maximum rated output in hot weather.
NOTE!
Any mounting location that restricts airflow may cause excessive
heating in the AC Module, causing reduced output. Do not mount the PV
panel flush to any surface.
NOTE!
Do not remove the leads or cable grips from the AC Module inverter
enclosure. Use only the cables and connectors provided.
When properly installed, AC Modules will resemble the layouts in Figure 5V or 5H. AC
Modules may be mounted either vertically (Figure 3, Illustration „V‟) or horizontally (Figure 3,
Illustration „H‟) with respect to the roof.
