WARN NG: ELECTR CAL HAZARD
All instructions should be read and understood before attempting to install,
wire, operate, and maintain the module. Contact with electrically active parts
of the module such as terminals can result in burns, sparks, and lethal shock
whether the module is connected or disconnected. Modules produce electricity when
sunlight or other sources illuminate the front face. The voltage from a single module
is not considered a shock hazard. When modules are connected in series, voltages are
additive. When modules are connected in parallel, current is additive. Consequently, a
multi-module system can produce high voltages and current, which constitute an increased
hazard and could cause serious injury or death.

GENERAL SAFETY
Follow All Permit, Installation, and Inspe tion Requirement
• Before installing a module, contact appropriate authorities to deter-
mine permit, installation, and inspection requirements that should be
followed. This should be done not only for installations in conjunc-
tion with buildings, but also for marine and motor vehicle applica-
tions for which additional requirements may apply.
• Electrically ground metal parts for all systems of any voltage.
• f not otherwise specified, it is recommended that the latest National
and nternational Electrical Code requirements be followed.
• The word "module" as used in this Guide refers to one or more solar
electric modules.
• Avoid electrical hazards when installing, wiring, operating and main-
taining the module.
• A module generates DC electricity when exposed to sunlight or
other light sources.
• Do not touch terminals while module is exposed to light or during in-
stallation. Provide suitable guards to prevent contact with 30VDC or
greater. As an added precaution, use properly insulated tools only.
• When installing or working with module or wiring, cover module face
completely with opaque material to halt production of electricity.
• t is recommended that the module remains packed in the box until
time of installation.
• Work only under dry conditions, with a dry module and tools.
• Do not drop module or allow objects to fall on module.
• Do not stand or step on module.
• Since sparks may be produced, do not install module where flam-
mable gases or vapors are present.
• Special construction may be required to help provide proper installa-
tion. When installing modules on any structure above ground, avoid
any possible falling safety hazards by following appropriate safety
practice(s) and using required safety equipment. Both roof construc-
tion and module installation design have an effect on the fire resist-
ance of the building. mproper installation may contribute to hazards
in the event of fire. Additional devices such as ground fault, fuses,
and disconnects may be required.
• Do not use modules of different configurations in the same system.
• Follow all safety precautions of other used components.
• Never leave a module unsupported or unsecured. f a module
should fall, the glass can break. A module with broken glass cannot
be repaired and must not be used.
• Keep back surface free from foreign objects.
• t must be assured that other system components do not generate
any hazard of any mechanical or electrical nature to the module.
• Do not artificially concentrate sunlight on the module.
• Avoid sharp edges.
• Module installation and operation should be performed by qualified
personnel only. Children should not be allowed near the solar elec-
tric installation.
• f not otherwise specified, it is recommended that requirements of
the latest local, national or regional electrical codes are followed.
• Use module for its intended function only. Follow all module manu-
facturers’ instructions. Do not disassemble the module, or remove
any part or label installed by the manufacturer. Do not treat the back
of the module with paint or adhesives.
• Retain this instruction booklet for future reference

The electrical characteristics are within ±5% of the indicated values of sc, Voc and Pmax under Standard Test Condi-
tions (STC)1. Depending on ambient conditions, time of day, time of year, and shading, the modules may produce
more current and/or voltage than reported at STC. Accordingly, the rated values of sc and Voc should be multiplied
by a factor of 1.25 when determining component voltage ratings, conductor ampacities, fuse size and the size of
controls connected to the PV output.

General Guidelines
When installing the m dules, be sure t :
1. Use only the provided cable for module interconnection. For all other use stranded copper single-conductor
type USE-2 cable, rated sunlight resistant. Refer to the National Electric Code and local requirements for
proper wiring.
2. Observe the requirements described under Module Ele tri al Chara teristi s in the Module Spe ifi ations
section of this Guide.
3. The module is non-framed and grounding of the module is not required, however all metallic parts used in the
installation have to be properly grounded. Refer to NEC articles 690 and 250.
4. All modules should be handled with care using proper safety equipment. Due to the weight of the module one
should never try to move a module without safety precautions and glass lifting equipment. Any glass lifting/han-
dling equipment can be used that is designed for the proper module weight and size.
5. Follow recommendations made by the licensed structural engineer or architect providing the project and
installation details.
6. Use only approved hardware. All hardware used to support the module has to be approved by a licensed
structural engineer for the specific project.
7. Make sure that two modules will never physically touch each other. Never use the module’s outer edges for
support, this may damage the module and void warranty.
8. When handling glass always wear safety glasses and follow all safety instructions in this manual.
Roof Preparation
Before installation of the solar modules, the roof needs to be properly prepared according to all local building
codes. Ensure that damaged/rotting plywood is repaired and that roofing felt (min. 30 lb) is installed for water-
proofing.
Basi Components
The Nu-lok SolarRoof™ modules are installed by integrating them directly into the Nu-lok slate support system.
The basic hardware for the solar panel installation consists of the same Nu-lok™ Link Channel, clip (Figure 2) and
the primary batten (Figure 3), that hold the roofing slate .
Figure 2 - Nu-lok™ Link Channel and Clip Figure 3 - Nu-lok™ Primary Battens

Rev 1.7 11/10/2010
Ins alla ion Procedure
Counter Battens
Before laying the Nu-lok™ Primary Battens, vertical counter battens must be installed. This prevents moisture
from collecting between the horizontal primary battens. t is recommended that a cedar lath or a 3/8” rubber shim
is used for the vertical counter battens. The counter battens must be nailed directly into the rafters.
Nu-lok™ Primary Battens
The horizontal primary battens are fastened into the counter battens at a distance of 12 1/4” center-to-center.
SolarRoof™ module installation using Nu-lok™
Link Channels and Clips
The link channels slide onto the primary battens as shown in Figure 4.
Three link channels should be used to support the center of each
solar module, while an additional two link channels should be used to
support the ends of the module (Figure 5). Adjacent modules will share
one link channel at the boundary between the two modules. The total
number of link channels needed for any given row of solar modules is
equal to: [4 x (# of modules in the row)] + 1

SolarRoof™ module installation using Nu-lok™ Link Channels and Clips (ontinued)
To install a SolarRoof™ module, simply slide it into the wire clips at the bottom of the link channels (Figure 6).
Because the modules overlap, it is best to start at the bottom row and work your way up the roof. An example
diagram of a SolarRoof™ layout is shown in Figure 7.

Wiring
Cables for module-to-module interconnections will be provided with your
SolarRoof™ modules. The cables are constructed of 10 gauge USE-2
sunlight resistant wire and Tyco SOLARLOK connectors (Figure 8).
n addition to module-to-module cables, home run cables are needed to
connect the series strings to a combiner/splice box. Home run cables are
available upon request. Please determine required length/quantity of home
run cables and contact your Nu-lok™ Roofing System sales
representative for a quote.
WARNING
Unplugging Under Load: PV plug connections must NOT be unplugged while under load. They can
be placed in a no load state by switching off the DC / AC converter or breaking the AC circuit.
Plugging and unplugging while under voltage is permitted. Make sure that the “DO NOT D SCON-
NECT UNDER LOAD” label is properly attached to each cable. Always use the provided cables, if custom cables
are required please contact the manufacturer or your local distributor for assistance.
