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.
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: indicates a hazardous situation which, if not
avoided, could result in injury or death.
Note
NOTE: indicates an important step or tip that leads to best
results, but is not safety or damage related.
REFER TO OPERATING INSTRUCTIONS: indicates that user should
refer to operating or installation instructions before
proceeding.
RISK OF ELECTRIC SHOCK: indicates components that present
risk of electrical shock.
General Compliance Information
Warning
Do not touch
non-insulated cable ends.
Warning
Do not touch the
DC conductors when energized.
Warning
Do not touch any
live components of the inverter.
Warning
Have the
inverter mounted, installed and commissioned only by qualified persons with the
appropriate skills.
Warning
If an error
occurs, have it rectified by qualified persons only.
Warning
Prior to
performing any work on the inverter, disconnect it from all voltage sources as
described in this document.
Warning
Connect and
ground the PV modules, array frame, and non-current carrying electrically
conductive components so that there is continuous conduction. Observe the
applicable local regulations.
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.
Warning
Risk of electric
shock and fire. Use only with PV modules with a maximum system voltage of rating
of 600 V or higher.
Warning
Equipment shall
be installed and operated in an environment within the ratings and limitations
of the equipment as published in these installation instructions.
Note
When using Eaton
branch breakers on continuous loads such as Tesla Solar Inverter, Eaton strongly
recommends using only type BR breakers that end in H (for instance BR260H).
CAUTION
Tesla Solar
Inverter shall not be installed within the PV array boundary as defined in NEC
Article 690.
