<br />All system labels and warnings to be installed at the site
<br />and their locations in accordance with Article 690 of the
<br />2019 California Electric Code and the Fire Department
<br />having jurisdiction Guidelines. The following labeling
<br />requirements apply to the "Rapid Shutdown" equipment.
<br />690.56 Identification of Power Sources.
<br />(C) Facilities with Rapid Shutdown.
<br />Buildings or structures with both utility service and a PV
<br />system, complying with 690.12, shall have a permanent
<br />plaque or directory including the following wording:
<br />PHOTOVOLTAIC SYSTEM EQUIPPED WITH
<br />RAPID SHUTDOWN
<br />The plaque or directory shall be reflective, with all
<br />letters capitalized and having a minimum height of 9.5mm,
<br />in white on red background.
<br />Permanent directory or plaque providing location of service
<br />disconnecting means and photovoltaic system disconnecting means, if
<br />not located at the same location. Plaques shall be metal or plastic, with
<br />engraved or machine printed letters, or electro-photo plating, in a
<br />contrasting color to the plaque. Plaques shall be permanently
<br />attached to the equipment or in the required location using an approved
<br />method that is suitable to withstand the environment to which it is
<br />exposed. Plaques and signage shall meet legibility, defacement,
<br />exposure, and adhesion requirements of Underwriters Laboratories
<br />marking and labeling system 969(UL969).
<br />Plaques will have red background with white lettering.
<br />MARKINGS, LABELS, AND WIRING SIGNS
<br />A. Purpose: Provide emergency responders with appropriate warning
<br />and guidance with respect to isolating solar electric system.
<br />B. Main Service Disconnect
<br />1. Residential buildings - The marking shall be placed within the main
<br />service disconnect. The marking shall be placed outside cover if
<br />the main service disconnect is operable with the service panel
<br />closed.
<br />2. Commercial buildings - The marking shall be placed adjacent to
<br />the main service disconnect clearly visible from the location
<br />where the level is operated.
<br />3. Markings: Verbiage, Format, and Type of Material
<br />a. Verbiage: CAUTION: SOLAR ELECTRIC SYSTEM CONNECTED
<br />b. Format: White lettering on a red background. Min 3/8" letter
<br />height. All letters capitalized. Arial or similar font, non bold.
<br />c. Material: Reflective, weather resistant material suitable for
<br />the environment (as per UL-969). Durable adhesive materials
<br />meet this requirement.
<br />C. Marking requirements on DC conduit, raceways, enclosures, cable
<br />assemblies, DC combiners, and junction boxes:
<br />1. Markings: Verbiage, Format, and Type of Material.
<br />a. Placement: Markings shall be placed every 10 feet on all interior
<br />and exterior DC conduits, raceways, enclosures, and cable
<br />assemblies, at turns, above and below penetrations, all DC
<br />combiners and junction boxes.
<br />b. Verbiage: CAUTION: SOLAR CIRCUIT (Note: the format and type
<br />of material shall adhere to "V. V-3b, c" of this requirement.)
<br />c. Inverters are not required to have caution markings.
<br />2. Marking is required on all interior and exterior DC conduit,
<br />raceways, enclosures, cable assemblies, and junction boxes,
<br />combiner boxes, and disconnects. CFC 605.11.1
<br />3. The materials used for marking shall be reflective, weather
<br />reflective, weather resistant materials suitable for the
<br />environment. Minimum 3/8" letter height; all upper case, Arial or
<br />similar font; Red background with white lettering. CFC 605.11.1
<br />4. Marking shall contain the words: WARNING: PHOTOVOLTAIC POWER
<br />SOURCE. CFC 605.11.1.2
<br />5. Marking shall be placed adjacent to the main service disconnect in
<br />a location clearly visible from the location where the disconnect
<br />is operated. CFC 605.11.1.3
