Installation Guide_PV-ezRack ComT V2.0  (September 2020)

Introduction

1. Introduction

The PV-ezRack

®

 ComT™ is developed for PV 

installation on flat or pitched roofs. The unique 
fixing parts can be quickly and easily installed 
with simple tools.
Please review this manual thoroughly before 
installing PV-ezRack

®

 ComT™. This manual 

provides:
1) Supporting documentation for building 
permit applications relating to PV-ezRack

®

 

ComT™.
2) Planning and installation instructions.

The PV-ezRack

®

 ComT™ parts, when 

installed in accordance with this guide, will 
be structurally sound and will meet the AS/
NZS1170.2:2011 Amdt 2- 2016 standard. 
During installation, and especially when 
working on the roof, please comply with the 
appropriate Occupational Health and Safety 
regulations. Please also pay attention to any 
other relevant State or Federal regulations. 
Please check that you are using the latest 
version of the Installation Manual, which you 
can do by contacting Clenergy Australia via 
email on [email protected], or contacting 
your local distributor in Australia.

The installer is solely responsible for: 

• Complying with all applicable local or national  
   building codes, including any updates that   
   may supersede this manual;
• Ensuring that PV-ezRack and other products 
   are appropriate for the particular installation   
   and the installation environment;
• Using only PV-ezRack parts and installer-
   supplied parts as specified by PV-ezRack   
   project plan (substitution of parts may void the    
   warranty and invalidate the letter of certification);
• Recycling: Recycle according to the local 
   relative statute;
• Removal: Reverse installation process;
• Ensuring that there are no less than 
   two professionals working on panel installation;
• Ensuring the installation of related 
   electrical equipment is performed by licenced 
   electricians;
• Ensuring safe installation of all electrical 
   aspects of the PV array, This includes adequate  
   earth bonding of the PV array and PV-ezRack

®

 

   SolarRoof™ components as  required in AS/ 
   NZS 5033-2014 AMDT 2 2-2018;
• Ensuring that the roof, its rafters/purlins, 
   connections, and other structural support 
   members can support the array under building 
   live load conditions;
• Ensuring that screws to fix interfaces have 
   adequate pullout strength and shear capacities 
   as installed;
• Maintaining the waterproof integrity of the roof, 
   including selection of appropriate flashing;
• Verifying the compatibility of the installation 
   considering preventing electrochemical 
   corrosion between dissimilar metals. This 
   may occur between structures and the building 
   and also between structures, fasteners and PV 
   modules, as detailed in AS/NZS 5033: 2014.
• Verifying atmospheric corrosivity zone of    
   installation site by referring to AS 4312-2008    
   or consulting local construction business to    
   determine appropriate products and installations.
