COMPANY, CONTACT, AND PRODUCT INFORMATIONSDS Information
Safety Data Sheets (SDS) are a requirement of the Globally Harmonized System of Classification andLabeling of Chemicals (GHS). This Hazard Communication Standard does not apply to various subcategories
including anything defined by OSHA as an “article.” OSHA has defined “article” as a manufactured item
other than a fluid or particle; (i) which is formed to a specific shape or design during manufacture; (ii) which
has end use function(s) dependent in whole or in part upon its shape or design during end use; and (iii)
which under normal conditions of use does not release more than very small quantities (e.g., minute or trace
amounts) of a hazardous chemical, and does not pose a physical hazard or health risk to employees.
Tesla Energy Products referenced herein meet the OSHA and EU CLP definition of “article.” Thus, they are
exempt from the requirements of the Hazard Communication Standard and do not require an SDS per OSHA
or EU CLP.
NOTE: For projects in Australia or New Zealand, contact your Tesla representative for the product's
safety data sheet.

PLANNING
V3 Supercharger Site Layout
NOTE: No two sites are identical, but the switchgear and Supercharger cabinets are typically inside
an enclosure or in a closed off area with limited visibility to the public, and within 100 feet (~30
meters) of the Supercharger stalls.
NOTE: For Pre-Assembled Supercharger Unit (PSU) sites, the V3 cabinets are co-located with theposts and each one has a disconnect mounted to the side of the cabinet. There may or may not be aswitchgear upstream of the cabinets with a main disconnect. In some cases, the individual PSUs are
fed directly from the utility transformer. For a visual reference of the PSU, see Identifying
Supercharger Variant on page 8.

3. V3 Cabinet◦ AC side: Inputs 3-phase AC power from grid (~380-480 V)◦ Shared bus DC side: Inputs and outputs DC power (~900 V)◦ V3 Charge Post DC side: Outputs DC power (vehicle pack voltage)
4. Tesla System Controller or Charging Gateway - provides site connectivity and cabinet control.
◦ The Tesla System Controller can be a stand-alone, represented as #4 in the image on the left or
integrated into switchgear/disconnect, as represented in the image on the right.
◦ Whether standalone or integrated into switchgear, one conduit must run from the Tesla System
Controller to every V3 Cabinet (see 8 in table below).
5. V3 Charge Post - receives DC power from V3 Cabinet and charges vehicle.

V2 and Urban Superchargers Site Layouts
Exact layout and configuration may vary by site.
NOTE: No two sites are identical, but the switchgear and Supercharger cabinets are typically inside
an enclosure or in a closed off area with limited visibility to the public, and within 100 feet (~30
meters) of the Supercharger stalls.
Each V2 Supercharger site is supplied by a utility transformer. The AC power is split by branch breakers toeach cabinet within the switchgear. Each V2 cabinet supplies two charge posts.
Here is an example of a V2 supercharger site where each cabinet supplies power to two charge posts. Notethat the utility transformer and switchgear are not shown in this image.

Electrical fires should be extinguished by de-energizing the electrical source, if possible, then using CO2 (orother appropriate electrical fire suppression). Vehicle fires can be extinguished with water if the standard
combustible materials on the vehicle are on fire (i.e., not the battery).
Extinguish small fires that do not involve a high voltage battery or electrical, using a CO2, ABC or water
extinguisher.
During overhaul, do not make contact with any high voltage components or wiring. Use insulated tools andappropriate HV PPE, if available. If using non-insulated tools, use extreme caution when interacting with live
electrical components.

Firefighter PPE
Firefighters should wear self-contained breathing apparatuses (SCBAs) and structural firefighting gear.
Industry testing has shown that standard structural firefighting gear provides adequate protection.

Site Disconnect Considerations
REVIEW ALL NOTES AND WARNINGS BEFORE ATTEMPTING TO DISCONNECT POWER TO A
SUPERCHARGER SITE.
WARNING: Do not attempt to reset the breaker to disconnect.
WARNING: Do not attempt to disconnect power to the site via the Supercharger cabinets.
Supercharger cabinets must only be shut off via the branch breakers in the switchgear. Switchgear
configurations and equipment may vary by site.
NOTE: Switchgear is typically within 100 feet of the Supercharger posts and may be inside an
enclosure. However, the location may vary by site.
NOTE: If the main breaker is inoperable or malfunctioning: Locate every branch breaker and turnthem downward to the OFF position. Energy may still be present between the branch breaker andmain breaker.
NOTE: If the switchgear is inoperable or appears to have major damage: Contact the utility company
to disconnect power from the grid.
NOTE: If entering an enclosure, use bolt cutters to cut the locks. Do not cut into any Tesla products
unless absolutely necessary.

NOTE: Switchgear typically consists of two or three bays, each with their own door. Exact
configurations vary by site.

RESPONSE
Turning Off Power to the Entire Supercharger SiteWARNING: ALWAYS ASSUME THAT ALL HIGH VOLTAGE COMPONENTS ARE ENERGIZED. Cutting,crushing, or touching high voltage components may result in serious injury or death.
1. Enter the locked enclosure, using bolt cutters to cut padlocks if needed. Do not open the locks on the
Supercharger cabinets. Locate the main disconnect for the site; it may be in the transformer station.
NOTE: Sites may not have an enclosure around the equipment.
2. Locate the electrical switchgear associated with the Supercharger cabinets on site.

NOTE: Some sites may not have a single switchgear with a main breaker. Sometimes, there is acollection of individual disconnects for each V3/V4 cabinet. This applies to standard sites and
PSU sites.

3. To disconnect all power to the site:
a. If there is an E-Stop device, engage the E-stop. This will trip the main feeder breaker and otherauxiliary equipment.
b. Locate the main feeder breaker (typically in the middle bay of the switchgear or in thetransformer station) and turn the handle downward to the OFF position. If the main breakercannot be safely disconnected, contact the local Utility company to remotely de-power the site.
Note that this may de-power adjacent power stations.
c. De-power all downstream breakers feeding the cabinets, as well as any upstream breakers
feeding into the site.
d. If the cabinets have a breaker box attached to their side, open the breaker box and de-power
the breaker for each cabinet.

WARNING: If the site is connected to an ESS (e.g., Megapack, Powerpack), isolate the ESS from thecharging system using an e-stop and ensure all breakers feeding from the ESS are disconnected.
NOTE: If both the main breaker and branch breakers are inoperable or have major damage, contact
the utility company to disconnect power from the grid.
NOTE: Turn off all breakers on sites with no main breakers.

RESPONSE
Turning Off Power to Supercharger Cabinet
WARNING: Turning the DC Disconnect handle on a V3 Supercharger cabinet to the OFF position
alone will NOT de-energize the cabinet.

The only way to disconnect power to a single V3 Supercharger cabinet is to disconnect power to the whole
site via the site's main breaker (or the cabinet's individual breaker, depending on site). The reason for this isdue to the shared DC bus connecting the cabinets.
