Installation and Safety Manual
Trinasmart
IMPORTANT SAFETY INSTRUCTIONS
SAVE THESE INSTRUCTIONS
• This manual contains important instructions for the installation and maintenance of the Trinasmart
Optimizer System Integrated PV Module and J-Box
• Risk of Electric Shock, Do Not Remove Cover. No user serviceable parts inside. Refer servicing to
qualified service personnel.
• Before installing or using the Trinasmart Optimizer System, please read all instructions and warning
markings on the Trina Solar products, appropriate sections of your inverter manual, photovoltaic (PV)
module installation manual, and other available safety guides.
• Failure to adhere to these instructions may result in injury or death, damage to the system, and
voiding the factory warranty.
• To reduce risk of fire and shock hazard, install this device with strict adherence to National Electric
Code (NEC) ANSI/NFPA 70 and/or local Electrical Codes. When the photovoltaic array is exposed to
light, it supplies a DC voltage to the Trinasmart Module Optimizer. The Trinasmart Optimizer will start
in the “on” state and its output voltage may be as high as the PV module open circuit voltage (Voc)
when connected to the module. The installer should use the same caution when handling electrical
cables from a PV module with or without the Trinasmart Optimizer attached.
• Installation must be performed by trained professionals only. Trina Solar does not assume liability for
loss or damage resulting from improper handling, installation, or misuse of products.
• To avoid risk of electrical shock or fire, do not attempt to disassemble or repair the product.
• Remove all metallic jewelry prior to installing the Trinasmart Module Optimizer to reduce the risk of
contacting live circuitry. Do not attempt to install in inclement weather.
• Do not operate the Trinasmart Module Optimizer if it has been physically damaged. Check existing
cables and connectors, ensuring they are in good condition and appropriate in rating. Do not
operate the Trinasmart Module Optimizers with damaged or substandard wiring or connectors. The
Trinasmart Module Optimizer should be mounted at a minimum of 3 feet above ground.
• Do not connect or disconnect under load. Authorized service personnel should reduce the risk of
electrical shock by pressing the Trinasmart PV-Safe button on the Trinasmart Management Unit
and disconnecting the AC and DC power from the system before attempting any maintenance or
working on any electrical circuits connected to the Module Optimizers. Turning off the Inverter and/
or the Trinasmart Optimizer may not reduce this risk. Internal capacitors within the inverter can
remain charged for several minutes after disconnecting all power sources.
Units are shown in SI (English).
