3-1 Instructions before Installation
• LG AC module is a “Grid Support Utility Interactive Inverter”, which requires approval from the
corresponding authority prior to connection with the utility grid. Contact the applicable local
government agencies and/or utility company.
•
Installation, maintenance, and supervision may only be carried out by a qualified and authorized
installer to ensure the safety of workers and systems.
•
Read and follow the installation guidelines specified in this manual. Installation with unapproved
methods may result in injuries including fatal injuries and/or damage to the equipment.
•
If it is necessary to use an installation method which is not specified in the installation manual,
please contact LG Electronics. Failure to comply may void the warranty and the module certificate.
• After arrival of AC modules, check for possible damage during transportation. Damaged modules
should not be installed. Request an exchange by contacting LG Electronics.
• Secure all necessary permits and licenses to install the solar modules.
• Store the AC modules in original packing before installation.
• Keep the AC modules in a clear and secured area. Any particles or moisture may cause malfunction
of AC cable’s contactors.
• Consider the weight of AC module before installation.
• Do not work alone. Install AC modules with a team of at least 2 persons for safe installation.
• To prevent the risk of accidents, use proper PPE (Personal Protective Equipment) including
helmets and gloves at all times.
• If installation location is high above ground, make sure to use Fall Protection System during the
installation.
• Plan the installation work in moderate weather. There is a risk of electric shock when it is raining
or snowing.
• Partial shadowing may substantially reduce energy production.
•
Check whether all parts used for the installation are certified for outdoor usage.
• Keep the solar module and system away from children at all times.
• During the AC module installation, do not let children play near the module and the system.
• Care must be taken to avoid low tilt angles which may cause dirt to buildup on the glass. A buildup
of dirt may cause performance degradation.
•
Dirt build-up on the surface of the panel may cause active solar cells to be shaded and electrical
performance to be impaired.
• Carry out the installation according to the local electric code.
