This manual describes proper installation procedures and provides necessary standards required for product reliability.

Warranty details are

available on website

. 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 fire 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

and

Certification Letters

to confirm design specifications.

• Ensure provided information is accurate. Issues resulting from inaccurate information are the installer’s responsibility.

• Validate foundation parameters prior to installation, as a local geotechnical report may be required to assess ground

conditions. We recommend consulting with a local engineer familiar with local regulations and build site requirements,

including soil conditions, terrain and load criteria. All parameters may impact foundation requirements.

• 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. If corrosion is

found, replace affected components 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.
