DISCLAIMER
This manual describes proper installation procedures and provides necessary standards required for product reliability.
Warranty details are available at IronRidge.com. All installers must thoroughly read this manual and have a clear
understanding of the installation procedures prior to installation. Failure to follow these guidelines may result in property
damage, bodily injury or even death.
IT IS THE INSTALLER’S RESPONSIBILITY TO:
• Ensure safe installation of all electrical aspects of the array. All electrical installation and procedures should be
conducted by a licensed and bonded electrician or solar contractor. Routine maintenance of a module or panel shall
not involve breaking or disturbing the bonding path of the system. All work must comply with national, state and local
installation procedures, product and safety standards.
• Comply with all applicable local or national building and re codes, including any that may supersede this manual.
• Ensure all products are appropriate for the installation, environment, and array under the site’s loading conditions.
• Use only IronRidge parts or parts recommended by IronRidge; substituting parts may void any applicable warranty.
• Review the Design Assistant to conrm design specications.
• Ensure provided information is accurate. Issues resulting from inaccurate information are the installer’s responsibility.
• Ensure bare copper grounding wire does not contact aluminum and zinc-plated steel components, to prevent risk of
galvanic corrosion.
• If loose components or loose fasteners are found during periodic inspection, re-tighten immediately. Any components
showing signs of corrosion or damage that compromise safety shall be replaced immediately.
• Provide an appropriate method of direct-to-earth grounding according to the latest edition of the National Electrical
Code, including NEC 250: Grounding and Bonding, and NEC 690: Solar Photovoltaic Systems.
• Disconnect AC power before servicing or removing modules, AC modules, microinverters and power optimizers.
• Review module manufacturer’s documentation for compatibility and compliance with warranty terms and conditions.
CAUTION: Module removal may disrupt the bonding path and could introduce the risk of electric shock. If during servicing
a module is required to be removed, a bonding jumper shall be installed between the adjacent modules from where the
module was removed to maintain the bond path.
