FIRE SAFETY REQUIREMENTS:

MARKINGS REQUIRED AND INSTALLED PER 2015 NFPA1.11.12

11.12.2.1.1 MAIN SERVICE DISCONNECT MARKING. A LABEL SHALL BE

PERMANENTLY AFFIXED TO THE MAIN SERVICE DISCONNECT PANEL SERVING

ALTERNATING CURRENT (AC) AND DIRECT CURRENT (DC) PHOTOVOLTAIC

SYSTEMS. THE LABEL SHALL BE RED WITH WHITE CAPITAL LETTERS AT LEAST

3/4 IN. (19 IN HEIGHT AND IN A NONSERIF FONT, TO READ:

“WARNING: PHOTOVOLTAIC POWER SOURCE"

THE MATERIALS USED FOR THE LABEL SHALL BE REFLECTIVE, WEATHER

RESISTANT, AND SUITABLE FOR THE ENVIRONMENT.

11.12.2.1.2 CIRCUIT DISCONNECTING MEANS MARKING. A PERMANENT LABEL

SHALL BE AFFIXED ADJACENT TO THE CIRCUIT BREAKER CONTROLLING THE

INVERTER OR OTHER PHOTOVOLTAIC SYSTEM ELECTRICAL CONTROLLER

SERVING AC AND DC PHOTOVOLTAIC SYSTEMS. THE LABEL SHALL HAVE

CONTRASTING COLOR WITH CAPITAL LETTERS AT LEAST 3/8 IN. (10 MM) IN

HEIGHT AND IN A NONSERIF FONT, TO READ:

“PHOTOVOLTAIC DISCONNECT.”

THE LABEL SHALL BE CONSTRUCTED OF DURABLE ADHESIVE MATERIAL OR

OTHER APPROVED MATERIAL.

11.12.2.1.3* CONDUIT, RACEWAY, ENCLOSURE, CABLE ASSEMBLY, AND JUNCTION

BOX MARKINGS. MARKING SHALL BE REQUIRED ON ALL INTERIOR AND EXTERIOR

DC CONDUITS, RACEWAYS, ENCLOSURES, CABLE ASSEMBLIES, AND JUNCTION

BOXES.

11.12.2.1.3.1 MARKING LOCATIONS. MARKING SHALL BE PLACED ON ALL DC

CONDUITS, RACEWAYS, ENCLOSURES, AND CABLE ASSEMBLIES EVERY 10 FT

(3048 MM), AT TURNS, AND ABOVE AND BELOW PENETRATIONS. MARKING SHALL

BE PLACED ON ALL DC COMBINER AND JUNCTION BOXES.

11.12.2.1.3.2* MARKING CONTENT AND FORMAT. MARKING FOR DC CONDUITS,

RACEWAYS, ENCLOSURES, CABLE ASSEMBLIES, AND JUNCTION BOXES SHALL

BE RED WITH WHITE LETTERING WITH MINIMUM 3/8 IN. (10 MM) CAPITAL LETTERS

IN A NONSERIF FONT, TO READ:

“WARNING: PHOTOVOLTAIC POWER SOURCE.”

MARKING SHALL BE REFLECTIVE, WEATHER RESISTANT, AND SUITABLE FOR THE

ENVIRONMENT.

11.12.2.1.5 INSTALLER INFORMATION. SIGNAGE, ACCEPTABLE TO THE AHJ,

SHALL BE INSTALLED ADJACENT TO THE MAIN DISCONNECT INDICATING THE

NAME AND EMERGENCY TELEPHONE NUMBER OF THE INSTALLING

CONTRACTOR.

11.12.2.2.1.2 PITCH. DESIGNATION OF RIDGE, HIP, AND VALLEY SHALL NOT

APPLY TO ROOFS WITH 2-IN-12 OR LESS PITCH

11.12.2.2.1.3 ROOF ACCESS POINTS. ROOF ACCESS POINTS SHALL BE DEFINED

AS AREAS WHERE FIRE DEPARTMENT LADDERS ARE NOT PLACED OVER

OPENINGS (WINDOWS OR DOORS), ARE LOCATED AT STRONG POINTS OF

BUILDING CONSTRUCTION, AND ARE IN LOCATIONS WHERE THEY WILL NOT

CONFLICT WITH OVERHEAD OBSTRUCTIONS (TREE LIMBS, WIRES, OR SIGNS).

11.12.2.2.4 LOCATION OF DIRECT CURRENT (DC) CONDUCTORS.

11.12.2.2.4.1 EXTERIOR-MOUNTED DC CONDUITS, WIRING SYSTEMS, AND

RACEWAYS FOR PHOTOVOLTAIC CIRCUITS SHALL BE LOCATED AS CLOSE AS

POSSIBLE TO THE RIDGE, HIP, OR VALLEY AND FROM THE HIP OR VALLEY AS

DIRECTLY AS POSSIBLE TO AN OUTSIDE WALL TO REDUCE TRIP HAZARDS

AND MAXIMIZE VENTILATION OPPORTUNITIES.

11.12.2.2.4.2 CONDUIT RUNS BETWEEN SUBARRAYS AND TO DC COMBINER

BOXES SHALL BE DESIGNED TO TAKE THE SHORTEST PATH FROM THE ARRAY

TO THE DC COMBINER BOX.

11.12.2.2.4.3 DC COMBINER BOXES SHALL BE LOCATED SO THAT CONDUIT

RUNS ARE MINIMIZED IN THE PATHWAYS BETWEEN ARRAYS.

11.12.2.2.4.4 DC WIRING SHALL BE RUN IN METALLIC CONDUIT OR RACEWAYS

WHERE LOCATED WITHIN ENCLOSED SPACES IN A BUILDING.

11.12.2.2.4.4.1 WHERE DC WIRING IS RUN PERPENDICULAR OR PARALLEL TO

LOAD-BEARING MEMBERS, A MINIMUM 10 IN. (254 MM) SPACE BELOW ROOF

DECKING OR SHEATHING SHALL BE MAINTAINED.

FIRE SAFETY INDICATIONS:

1. ROOF ACCESS POINT, PER NFPA 1 11.12.2.2.1.3

2. PV MODULES INSTALLED ON ROOF WITH ALUMINUM SOLARMOUNT

MOUNTING SYSTEM. THE MOUNTING SYSTEM IS CLASS A FIRE RATED

ON A 1/12 SLOPED ROOF WHEN INSTALLED WITH TYPE 1, 2, 3, OR 10

MODULES. THE LONGI SOLAR LR6 - 365W IS TYPE 1.

3. 4.0 FT. WIDE FIRE ACCESS PATHWAY, PER NFPA 1 11.10.2.2.2.1.3 AND

NFPA 1 11.10.2.2.2.1.2

4 RAPID SHUTDOWN (2014 NEC 690.12) FRONIUS INVERTER TO

TRIGGER BASED ON THE STATE OF AC GRID. IF AC VOLTAGE IS LOST,

I.E. DUE TO GRID FAILURE, OR MANUAL DISCONNECT, INVERTER

WILL SHUT DOWN, INTERRUPTING THE FLOW OF POWER FROM

THE PV ARRAY TO THE AC COLLECTION PANEL.

5. PHOTO VOLTAIC AC (MAIN SERVICE) DISCONNECT.
