Important Safety Instructions

This manual contains important instructions for the Tesla Solar Inverter (3.8 kW P/N 1534000-XX-Y and 7.6 kW P/N 1538000-XX-Y) and PV Rapid Shutdown Equipment Mid Circuit Interrupter (P/N MCI-1) that shall be followed during installation and maintenance of the Tesla Solar Inverter and PV Rapid Shutdown Equipment Mid Circuit Interrupter.

Informational PurposesAn informational icon, calling your attention
Note
The model numbers in this manual call out "-XX-Y" for the suffix of the equipment model number. The wild cards are defined as follows:
  • "X" is a number and the one number in the model number representing a style code; form, fit, and function are not changed, and these numbers have no bearing on compliance.
  • "Y" is a letter, and the one letter in the model number representing a pedigree; form, fit, and function are not changed, and this letter has no bearing on compliance.

All instructions must be read and understood before attempting to install, wire, operate, or maintain a PV system. Failure to read and comply with any of the limitations noted herein can result in property damage, serious bodily injury, or death. The installer assumes the risk of all injury that might occur during installation, including, without limitation, the risk of electric shock. Tesla Solar Roof is engineered to safely withstand applicable live loads required by building code for steep slope applications. However, to ensure safety and maintain maximum roof life, walking on a Solar Roof should be avoided except by trained Tesla Solar Roof installation professionals and first responders. This is a common recommendation for other high-end roof types, including slate, clay, concrete, and composite tile products.

  • Use qualified personnel for installation. Installing a solar electric system requires specialized skills and knowledge.
  • Abide by local, regional, and national statutory regulations when installing the system, and obtain a building permit if necessary.
  • Use equipment, connectors, and wiring suitable for solar electric systems.
  • Work under dry conditions and use dry tools.
  • Use fall protection when working from heights. Follow Occupational Safety and Health Act (OSHA) or local governing safety regulations regarding Fall Protection.
  • Use insulated tools that are approved for working on electrical installations.
  • Wear suitable personal protection equipment (PPE) to prevent the risk of personal injury, such as fall hazards or electrical hazards.
  • Consult your local authority for guidelines and requirements for building or structural fire safety.

Note to Trained Professionals

In the event of a fire at the premises, rapid shutdown equipment in the array will reduce voltages and control the hazard for firefighter operations. Nevertheless the array wiring should be treated as potentially dangerous, especially if it is damaged by heat or flames. Inform the fire crew about the particular hazards from the PV system, and stay away from all elements of the PV system during and after a fire until the necessary steps have been taken to make the PV system safe.

Symbols Used

CAUTION: indicates a hazardous situation which, if not avoided, could result in minor injury or damage to the equipment.

Warning
This Photovoltaic Rapid Shutdown Equipment (PVRSE) does not perform all of the functions of a complete Photovoltaic Rapid Shutdown System (PVRSS). This PVRSE must be installed with other equipment to form a complete PVRSS that meets the requirements of NEC (NFPA 70) section 690.12 for controlled conductors outside the array. Other equipment installed in or on this PV system may adversely affect the operation of the PVRSS. It is the responsibility of the installer to ensure that the completed PV system meets the Rapid Shutdown functional requirements. This equipment must be installed according to the manufacturer’s installation instructions.
